Intake Resonance Switchover Valve Circuit
Causes
- Open or shorted wiring in the resonance/runner valve control circuit
- Corroded, loose, or damaged connector or terminals at the valve
- Failed intake resonance switchover valve (solenoid/actuator)
- Blown fuse or faulty relay supplying the circuit (if applicable)
- Water intrusion or debris in connector/wiring
- ECM driver fault (rare) or poor ground
Symptoms
- Check Engine Light (MIL) illuminated
- Reduced engine performance or diminished midrange torque
- Hesitation or stumble on acceleration
- Erratic idle or mild roughness
- Possible reduced fuel economy
- Intake runner resonance not engaging (may be noticed as changed engine sound)
What to check
- Scan for stored/active codes and capture freeze-frame data
- Check live data / commanded state for the intake resonance valve with a scan tool
- Perform a careful visual inspection of the valve, connector, and wiring for damage or corrosion
- Backprobe the connector with key ON and engine OFF to verify supply voltage and ground reference
- Measure coil resistance of the valve solenoid and compare to specification
- Check continuity and resistance between valve connector and ECM pin (with power removed)
Signal parameters
- Supply voltage at valve harness pin: approximately battery voltage with key ON (check spec)
- Control signal: ECM typically switches ground/pulse to control solenoid — expect pulsed ground when commanded
- Solenoid coil resistance: check service information; typical intake solenoids often measure in the low tens of ohms (verify before replacing)
- No continuity to ground on the control pin when valve is not commanded (depends on design)
- Commanded state should change live-data bit/position when valve is driven by scan tool
Diagnostic algorithm
- Retrieve codes and freeze frame with a scan tool; note when the fault occurred (conditions).
- Visually inspect the valve, mounting, connector, and harness for damage, corrosion, or water entry. Repair obvious damage.
- With key ON (engine OFF) backprobe the connector: verify battery supply at the power feed pin and check the control pin for correct reference/ECM connection.
- Measure solenoid coil resistance (with harness disconnected). Compare to the vehicle/service specification; replace if open or out of spec.
- Check continuity between the valve connector pins and the ECM connector pins with power off. Repair any open or high-resistance wiring.
- If wiring checks OK, command the valve ON/OFF using a scan tool while monitoring voltage at the connector to verify the ECM is switching the circuit and the valve responds.
- If the valve does not respond to commanded activation but bench-testing the valve (apply proper voltage/ground) operates it, focus on harness/ECM wiring repair.
- If bench-tested valve fails, replace the resonance switchover valve/solenoid and re-test.
- After repairs, clear codes, perform operational test drive and re-scan to confirm the fault does not return and readiness is restored.
- If wiring and valve test good but code returns, check fuses/relays and consider ECM driver fault — consult advanced diagnostics/service manual before ECM replacement.
Likely causes
- Broken/chafed harness wire to the valve
- Corroded or worn connector causing intermittent contact
- Failed solenoid coil (open or high resistance)
- Valve stuck mechanically and drawing abnormal current
- Short to battery/ground caused by damaged insulation
- Faulty ECM output transistor (last resort after harness/valve verified)

P1113
Intake Resonance Switchover Valve Circuit
Causes
- Open or shorted wiring in the resonance/runner valve control circuit
- Corroded, loose, or damaged connector or terminals at the valve
- Failed intake resonance switchover valve (solenoid/actuator)
- Blown fuse or faulty relay supplying the circuit (if applicable)
- Water intrusion or debris in connector/wiring
- ECM driver fault (rare) or poor ground
Symptoms
- Check Engine Light (MIL) illuminated
- Reduced engine performance or diminished midrange torque
- Hesitation or stumble on acceleration
- Erratic idle or mild roughness
- Possible reduced fuel economy
- Intake runner resonance not engaging (may be noticed as changed engine sound)
What to check
- Scan for stored/active codes and capture freeze-frame data
- Check live data / commanded state for the intake resonance valve with a scan tool
- Perform a careful visual inspection of the valve, connector, and wiring for damage or corrosion
- Backprobe the connector with key ON and engine OFF to verify supply voltage and ground reference
- Measure coil resistance of the valve solenoid and compare to specification
- Check continuity and resistance between valve connector and ECM pin (with power removed)
Signal parameters
- Supply voltage at valve harness pin: approximately battery voltage with key ON (check spec)
- Control signal: ECM typically switches ground/pulse to control solenoid — expect pulsed ground when commanded
- Solenoid coil resistance: check service information; typical intake solenoids often measure in the low tens of ohms (verify before replacing)
- No continuity to ground on the control pin when valve is not commanded (depends on design)
- Commanded state should change live-data bit/position when valve is driven by scan tool
Diagnostic algorithm
- Retrieve codes and freeze frame with a scan tool; note when the fault occurred (conditions).
- Visually inspect the valve, mounting, connector, and harness for damage, corrosion, or water entry. Repair obvious damage.
- With key ON (engine OFF) backprobe the connector: verify battery supply at the power feed pin and check the control pin for correct reference/ECM connection.
- Measure solenoid coil resistance (with harness disconnected). Compare to the vehicle/service specification; replace if open or out of spec.
- Check continuity between the valve connector pins and the ECM connector pins with power off. Repair any open or high-resistance wiring.
- If wiring checks OK, command the valve ON/OFF using a scan tool while monitoring voltage at the connector to verify the ECM is switching the circuit and the valve responds.
- If the valve does not respond to commanded activation but bench-testing the valve (apply proper voltage/ground) operates it, focus on harness/ECM wiring repair.
- If bench-tested valve fails, replace the resonance switchover valve/solenoid and re-test.
- After repairs, clear codes, perform operational test drive and re-scan to confirm the fault does not return and readiness is restored.
- If wiring and valve test good but code returns, check fuses/relays and consider ECM driver fault — consult advanced diagnostics/service manual before ECM replacement.
Likely causes
- Broken/chafed harness wire to the valve
- Corroded or worn connector causing intermittent contact
- Failed solenoid coil (open or high resistance)
- Valve stuck mechanically and drawing abnormal current
- Short to battery/ground caused by damaged insulation
- Faulty ECM output transistor (last resort after harness/valve verified)

- If wiring and valve test good but code returns, check fuses/relays and consider ECM driver fault — consult advanced diagnostics/service manual before ECM replacement.
Likely causes
- Broken/chafed harness wire to the valve
- Corroded or worn connector causing intermittent contact
- Failed solenoid coil (open or high resistance)
- Valve stuck mechanically and drawing abnormal current
- Short to battery/ground caused by damaged insulation
- Faulty ECM output transistor (last resort after harness/valve verified)

Intake Resonance Switchover Valve Circuit
Causes
- Open or shorted wiring in the resonance/runner valve control circuit
- Corroded, loose, or damaged connector or terminals at the valve
- Failed intake resonance switchover valve (solenoid/actuator)
- Blown fuse or faulty relay supplying the circuit (if applicable)
- Water intrusion or debris in connector/wiring
- ECM driver fault (rare) or poor ground
Symptoms
- Check Engine Light (MIL) illuminated
- Reduced engine performance or diminished midrange torque
- Hesitation or stumble on acceleration
- Erratic idle or mild roughness
- Possible reduced fuel economy
- Intake runner resonance not engaging (may be noticed as changed engine sound)
What to check
- Scan for stored/active codes and capture freeze-frame data
- Check live data / commanded state for the intake resonance valve with a scan tool
- Perform a careful visual inspection of the valve, connector, and wiring for damage or corrosion
- Backprobe the connector with key ON and engine OFF to verify supply voltage and ground reference
- Measure coil resistance of the valve solenoid and compare to specification
- Check continuity and resistance between valve connector and ECM pin (with power removed)
Signal parameters
- Supply voltage at valve harness pin: approximately battery voltage with key ON (check spec)
- Control signal: ECM typically switches ground/pulse to control solenoid — expect pulsed ground when commanded
- Solenoid coil resistance: check service information; typical intake solenoids often measure in the low tens of ohms (verify before replacing)
- No continuity to ground on the control pin when valve is not commanded (depends on design)
- Commanded state should change live-data bit/position when valve is driven by scan tool
Diagnostic algorithm
- Retrieve codes and freeze frame with a scan tool; note when the fault occurred (conditions).
- Visually inspect the valve, mounting, connector, and harness for damage, corrosion, or water entry. Repair obvious damage.
- With key ON (engine OFF) backprobe the connector: verify battery supply at the power feed pin and check the control pin for correct reference/ECM connection.
- Measure solenoid coil resistance (with harness disconnected). Compare to the vehicle/service specification; replace if open or out of spec.
- Check continuity between the valve connector pins and the ECM connector pins with power off. Repair any open or high-resistance wiring.
- If wiring checks OK, command the valve ON/OFF using a scan tool while monitoring voltage at the connector to verify the ECM is switching the circuit and the valve responds.
- If the valve does not respond to commanded activation but bench-testing the valve (apply proper voltage/ground) operates it, focus on harness/ECM wiring repair.
- If bench-tested valve fails, replace the resonance switchover valve/solenoid and re-test.
- After repairs, clear codes, perform operational test drive and re-scan to confirm the fault does not return and readiness is restored.
- If wiring and valve test good but code returns, check fuses/relays and consider ECM driver fault — consult advanced diagnostics/service manual before ECM replacement.

P1113
Intake Air Temperature Sensor Signal Dynamic Chamber Circuit
Causes
- Open or shorted wiring in the resonance/runner valve control circuit
- Corroded, loose, or damaged connector or terminals at the valve
- Failed intake resonance switchover valve (solenoid/actuator)
- Blown fuse or faulty relay supplying the circuit (if applicable)
- Water intrusion or debris in connector/wiring
- ECM driver fault (rare) or poor ground
Symptoms
- Check Engine Light (MIL) illuminated
- Reduced engine performance or diminished midrange torque
- Hesitation or stumble on acceleration
- Erratic idle or mild roughness
- Possible reduced fuel economy
- Intake runner resonance not engaging (may be noticed as changed engine sound)
What to check
- Scan for stored/active codes and capture freeze-frame data
- Check live data / commanded state for the intake resonance valve with a scan tool
- Perform a careful visual inspection of the valve, connector, and wiring for damage or corrosion
- Backprobe the connector with key ON and engine OFF to verify supply voltage and ground reference
- Measure coil resistance of the valve solenoid and compare to specification
- Check continuity and resistance between valve connector and ECM pin (with power removed)
Signal parameters
- Supply voltage at valve harness pin: approximately battery voltage with key ON (check spec)
- Control signal: ECM typically switches ground/pulse to control solenoid — expect pulsed ground when commanded
- Solenoid coil resistance: check service information; typical intake solenoids often measure in the low tens of ohms (verify before replacing)
- No continuity to ground on the control pin when valve is not commanded (depends on design)
- Commanded state should change live-data bit/position when valve is driven by scan tool
Diagnostic algorithm
- Retrieve codes and freeze frame with a scan tool; note when the fault occurred (conditions).
- Visually inspect the valve, mounting, connector, and harness for damage, corrosion, or water entry. Repair obvious damage.
- With key ON (engine OFF) backprobe the connector: verify battery supply at the power feed pin and check the control pin for correct reference/ECM connection.
- Measure solenoid coil resistance (with harness disconnected). Compare to the vehicle/service specification; replace if open or out of spec.
- Check continuity between the valve connector pins and the ECM connector pins with power off. Repair any open or high-resistance wiring.
- If wiring checks OK, command the valve ON/OFF using a scan tool while monitoring voltage at the connector to verify the ECM is switching the circuit and the valve responds.
- If the valve does not respond to commanded activation but bench-testing the valve (apply proper voltage/ground) operates it, focus on harness/ECM wiring repair.
- If bench-tested valve fails, replace the resonance switchover valve/solenoid and re-test.
- After repairs, clear codes, perform operational test drive and re-scan to confirm the fault does not return and readiness is restored.
- If wiring and valve test good but code returns, check fuses/relays and consider ECM driver fault — consult advanced diagnostics/service manual before ECM replacement.
Likely causes
- Broken/chafed harness wire to the valve
- Corroded or worn connector causing intermittent contact
- Failed solenoid coil (open or high resistance)
- Valve stuck mechanically and drawing abnormal current
- Short to battery/ground caused by damaged insulation
- Faulty ECM output transistor (last resort after harness/valve verified)
