Multiple Cylinder Misfire With Fuel Cut-off
Causes
- Faulty ignition components (coils, spark plugs, wiring)
- Insufficient fuel delivery (low rail pressure, clogged pump/filter, faulty pressure regulator)
- Multiple clogged or leaking fuel injectors
- Mechanical problems (low compression, valve timing issues, head gasket leak)
- Intake or vacuum leaks affecting multiple cylinders
- Camshaft/crankshaft position sensor fault or timing correlation error
Symptoms
- Illuminated Check Engine Light with misfire/DTC present
- Rough idle and pronounced vibration
- Loss of power, hesitation or stumbling under load
- Poor fuel economy and increased emissions
- Possible limp-home behavior or reduced performance (fuel cut active)
- Intermittent or persistent stalling
What to check
- Read freeze frame and stored misfire counts with a capable scan tool
- Observe live data: per-cylinder misfire counters, fuel rail pressure, injector pulse width, ignition coil driver status
- Check short-term and long-term fuel trims and O2 sensor activity
- Perform a visual inspection of ignition coils, spark plugs and wiring harness connectors
- Measure fuel rail pressure (static and while cranking/running)
- Compression or cylinder leak-down test on all cylinders
Signal parameters
- Per-cylinder misfire counters (counts/min or total misfires)
- Crankshaft RPM stability / variation trace
- Fuel rail pressure (bar or psi) at idle and under load
- Injector pulse width (ms) and duty cycle
- Ignition coil primary/secondary waveforms (volts/mV)
- Short-term and long-term fuel trim (%)
Diagnostic algorithm
- Connect a qualified scan tool. Record freeze frame, misfire counts per cylinder, fuel rail pressure, fuel trims and related codes.
- Verify whether fuel cut-off was commanded (note fuel cut status in live data). Do not assume cause—treat as protective action.
- Perform a visual inspection: check for loose/disconnected vacuum lines, damaged ignition leads/coils, oil/fuel contamination on plugs.
- Check fuel system: measure static and dynamic fuel rail pressure vs. manufacturer spec; inspect fuel filter and pump operation.
- Test ignition: check spark plugs condition and gaps, swap coils between affected and known-good cylinders to see if misfire follows coil.
- Test injectors: monitor injector pulse and fuel spray (or swap injectors) to identify a faulty injector or driver channel.
- Mechanical checks: perform compression or leak-down test across all cylinders to rule out low compression or valve timing issues.
- Verify cam/crank sensors and timing: capture crank and cam sensor waveforms and check phase/timing consistency; inspect timing chain/belt and phasers if applicable.
- Inspect wiring and connectors to ECM/injector/coil circuits for corrosion, shorts, opens, or high resistance. Wiggle-test harness with scope if intermittent.
- Clear codes and perform a controlled road or dyno test while monitoring live parameters to confirm repair or reproduce fault.
- If no hardware fault found, check for software updates/TSBs and consider ECM/driver module testing or replacement as a last resort.
Likely causes
- Weak or failing ignition coils affecting several cylinders
- Fuel rail pressure low or intermittent (fuel pump or regulator issue)
- Timing chain/belt jump or cam/phaser failure causing multiple misfires
- Severe vacuum leak or intake manifold gasket failure
- Multiple injector fouling or ECM driver circuit failure

#1 ION CIRCUIT
Causes
- Faulty ignition components (coils, spark plugs, wiring)
- Insufficient fuel delivery (low rail pressure, clogged pump/filter, faulty pressure regulator)
- Multiple clogged or leaking fuel injectors
- Mechanical problems (low compression, valve timing issues, head gasket leak)
- Intake or vacuum leaks affecting multiple cylinders
- Camshaft/crankshaft position sensor fault or timing correlation error
Symptoms
- Illuminated Check Engine Light with misfire/DTC present
- Rough idle and pronounced vibration
- Loss of power, hesitation or stumbling under load
- Poor fuel economy and increased emissions
- Possible limp-home behavior or reduced performance (fuel cut active)
- Intermittent or persistent stalling
What to check
- Read freeze frame and stored misfire counts with a capable scan tool
- Observe live data: per-cylinder misfire counters, fuel rail pressure, injector pulse width, ignition coil driver status
- Check short-term and long-term fuel trims and O2 sensor activity
- Perform a visual inspection of ignition coils, spark plugs and wiring harness connectors
- Measure fuel rail pressure (static and while cranking/running)
- Compression or cylinder leak-down test on all cylinders
Signal parameters
- Per-cylinder misfire counters (counts/min or total misfires)
- Crankshaft RPM stability / variation trace
- Fuel rail pressure (bar or psi) at idle and under load
- Injector pulse width (ms) and duty cycle
- Ignition coil primary/secondary waveforms (volts/mV)
- Short-term and long-term fuel trim (%)
Diagnostic algorithm
- Connect a qualified scan tool. Record freeze frame, misfire counts per cylinder, fuel rail pressure, fuel trims and related codes.
- Verify whether fuel cut-off was commanded (note fuel cut status in live data). Do not assume cause—treat as protective action.
- Perform a visual inspection: check for loose/disconnected vacuum lines, damaged ignition leads/coils, oil/fuel contamination on plugs.
- Check fuel system: measure static and dynamic fuel rail pressure vs. manufacturer spec; inspect fuel filter and pump operation.
- Test ignition: check spark plugs condition and gaps, swap coils between affected and known-good cylinders to see if misfire follows coil.
- Test injectors: monitor injector pulse and fuel spray (or swap injectors) to identify a faulty injector or driver channel.
- Mechanical checks: perform compression or leak-down test across all cylinders to rule out low compression or valve timing issues.
- Verify cam/crank sensors and timing: capture crank and cam sensor waveforms and check phase/timing consistency; inspect timing chain/belt and phasers if applicable.
- Inspect wiring and connectors to ECM/injector/coil circuits for corrosion, shorts, opens, or high resistance. Wiggle-test harness with scope if intermittent.
- Clear codes and perform a controlled road or dyno test while monitoring live parameters to confirm repair or reproduce fault.
- If no hardware fault found, check for software updates/TSBs and consider ECM/driver module testing or replacement as a last resort.
Likely causes
- Weak or failing ignition coils affecting several cylinders
- Fuel rail pressure low or intermittent (fuel pump or regulator issue)
- Timing chain/belt jump or cam/phaser failure causing multiple misfires
- Severe vacuum leak or intake manifold gasket failure
- Multiple injector fouling or ECM driver circuit failure

P1341
Camshaft Position Sensor B Range / Performance
Causes
- Faulty ignition components (coils, spark plugs, wiring)
- Insufficient fuel delivery (low rail pressure, clogged pump/filter, faulty pressure regulator)
- Multiple clogged or leaking fuel injectors
- Mechanical problems (low compression, valve timing issues, head gasket leak)
- Intake or vacuum leaks affecting multiple cylinders
- Camshaft/crankshaft position sensor fault or timing correlation error
Symptoms
- Illuminated Check Engine Light with misfire/DTC present
- Rough idle and pronounced vibration
- Loss of power, hesitation or stumbling under load
- Poor fuel economy and increased emissions
- Possible limp-home behavior or reduced performance (fuel cut active)
- Intermittent or persistent stalling
What to check
- Read freeze frame and stored misfire counts with a capable scan tool
- Observe live data: per-cylinder misfire counters, fuel rail pressure, injector pulse width, ignition coil driver status
- Check short-term and long-term fuel trims and O2 sensor activity
- Perform a visual inspection of ignition coils, spark plugs and wiring harness connectors
- Measure fuel rail pressure (static and while cranking/running)
- Compression or cylinder leak-down test on all cylinders
Signal parameters
- Per-cylinder misfire counters (counts/min or total misfires)
- Crankshaft RPM stability / variation trace
- Fuel rail pressure (bar or psi) at idle and under load
- Injector pulse width (ms) and duty cycle
- Ignition coil primary/secondary waveforms (volts/mV)
- Short-term and long-term fuel trim (%)
Diagnostic algorithm
- Connect a qualified scan tool. Record freeze frame, misfire counts per cylinder, fuel rail pressure, fuel trims and related codes.
- Verify whether fuel cut-off was commanded (note fuel cut status in live data). Do not assume cause—treat as protective action.
- Perform a visual inspection: check for loose/disconnected vacuum lines, damaged ignition leads/coils, oil/fuel contamination on plugs.
- Check fuel system: measure static and dynamic fuel rail pressure vs. manufacturer spec; inspect fuel filter and pump operation.
- Test ignition: check spark plugs condition and gaps, swap coils between affected and known-good cylinders to see if misfire follows coil.
- Test injectors: monitor injector pulse and fuel spray (or swap injectors) to identify a faulty injector or driver channel.
- Mechanical checks: perform compression or leak-down test across all cylinders to rule out low compression or valve timing issues.
- Verify cam/crank sensors and timing: capture crank and cam sensor waveforms and check phase/timing consistency; inspect timing chain/belt and phasers if applicable.
- Inspect wiring and connectors to ECM/injector/coil circuits for corrosion, shorts, opens, or high resistance. Wiggle-test harness with scope if intermittent.
- Clear codes and perform a controlled road or dyno test while monitoring live parameters to confirm repair or reproduce fault.
- If no hardware fault found, check for software updates/TSBs and consider ECM/driver module testing or replacement as a last resort.
Likely causes
- Weak or failing ignition coils affecting several cylinders
- Fuel rail pressure low or intermittent (fuel pump or regulator issue)
- Timing chain/belt jump or cam/phaser failure causing multiple misfires
- Severe vacuum leak or intake manifold gasket failure
- Multiple injector fouling or ECM driver circuit failure
