Causes
- Short to ground in the intake valve control solenoid control wire (Bank 2)
- Failed intake valve control/VVT solenoid (internal short or open)
- Poor or corroded connector or terminals at the solenoid
- Damaged wiring harness (chafing, pinched, broken conductor)
- Faulty ECM/PCM output driver or internal ground issue
- Low battery or poor battery/charging system voltage during test
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Reduced engine performance or power
- Rough idle or misfire-like symptoms
- Poor fuel economy
- Loss or reduced operation of variable valve timing on Bank 2
- Stored or pending related DTCs
What to check
- Scan for codes and read freeze frame data; note battery voltage and engine conditions when code set
- Visually inspect harness and connector at Bank 2 intake valve control solenoid for corrosion, damage, oil contamination or loose pins
- Check battery voltage and charging system; ensure battery is adequately charged (12.4–12.8 V at rest)
- Measure resistance of the solenoid coil (spec below) with connector disconnected
- Back-probe the control connector and check voltage while commanding the solenoid ON/OFF with a scan tool
- Perform continuity and short-to-ground checks on the control wire to the ECM
Signal parameters
- Expected when deactivated (command OFF): control/command circuit should be near battery voltage (roughly 11–14 V) if the ECM uses a low-side driver
- Expected when activated (command ON): control circuit should be near 0–1 V (ground) if ECM switches to ground
- Fault condition: voltage remains low (below the manufacturer's low-voltage threshold) when it should be at battery voltage — indicates short to ground or stuck-low
- Solenoid coil resistance typical range: ~6–30 ohms (varies by vehicle); consult service data for exact value
Diagnostic algorithm
- Safety: Park, key off, disconnect battery if required for connector inspection.
- Retrieve freeze frame and live data; note battery voltage and engine state when the code set.
- Visually inspect the Bank 2 intake control solenoid connector and wiring for damage, oil, and corrosion; repair as needed.
- With ignition off, disconnect solenoid and measure coil resistance between power and control pins; compare to spec. Infinite or very high = open coil; near 0 = short.
- Check for short to ground: with harness disconnected, measure continuity from the control wire to chassis ground. Low resistance indicates a short.
- Back-probe the solenoid connector. With key on (engine off) and using a scan tool, command the solenoid ON/OFF and observe voltage: OFF should be near battery voltage, ON should go to ~0–1 V (or the reverse depending on system).
Likely causes
- Corroded or loose connector at the Bank 2 intake valve control solenoid
- Control wire shorted to chassis ground (pinched harness)
- Failed solenoid (shorted coil or internal electronics)
- Faulty ECM driver (less common)
