Causes
- Oil control valve (camshaft profile actuator) mechanically stuck or seized
- Short to battery or high-side short in the actuator control circuit
- Failed oil control valve (electrical coil open/shorted)
- Dirty or low engine oil preventing actuator movement
- Faulty connector, damaged wiring, or poor ground
- Defective Powertrain Control Module (PCM) or driver transistor
Symptoms
- Check Engine Light (MIL) illuminated
- Reduced engine performance or power
- Rough idle or hesitation, especially at low speed
- Poor fuel economy and increased emissions
- Noise from top end when VVT should be switching
- Possible hard starting or limp-home mode on some vehicles
What to check
- Read freeze frame and live data for camshaft actuator command and actual position for Bank 2
- Verify engine oil level, condition and service history
- Inspect actuator connector and wiring for damage, corrosion or shorts
- Measure voltage at actuator connector with key ON/engine running while commanding actuator
- Check resistance of the actuator/solenoid (compare to factory spec)
- Scan for additional cam/crank correlation or bank 1 codes
Signal parameters
- Control signal type: PCM-controlled solenoid — typically switched 12 V or PWM ground-switched (varies by vehicle)
- Expected ON voltage at connector: near battery voltage (~11–14 V) when driven high, or 0 V when driven to ground depending on design
- Expected OFF voltage: open or pulled to opposite side (consult OEM spec); you should not see constant battery voltage when command is OFF
- Typical actuator coil resistance: varies by manufacturer (commonly single-digit to few tens of ohms). Compare to factory spec before assuming failure
- Current draw: when activated may be hundreds of mA up to ~1–2 A depending on design; use manufacturer data
Diagnostic algorithm
- Verify code and record freeze-frame, then clear codes and attempt to reproduce the fault to confirm persistence.
- Check engine oil level and condition; if dirty or low, correct and retest (contaminated oil can jam VVT actuators).
- Visually inspect Bank 2 actuator connector and wiring from PCM to actuator for damage, chafing, corrosion, or pin push-out.
- With connectors disconnected, measure actuator coil resistance and compare to specification. If open/shorted or out of range, replace actuator/OCV.
- Backprobe the actuator connector while commanding the actuator ON/OFF with a scan tool. Verify the PCM command changes and that the harness delivers the expected voltage or ground.
- If the harness shows constant battery voltage or ground regardless of PCM command, trace harness for short to power/ground and repair as needed.
- If the harness signals are correct but the actuator does not respond (mechanical stuck), remove and bench-test the actuator/ocv. Replace if mechanically seized.
- If actuator and wiring check good but command remains ON and PCM output never changes, suspect PCM driver fault—verify with manufacturer procedures before replacing PCM.
- After repairs, clear codes and perform a road test and live data verification to ensure cam actuator follows commanded position and no further codes set.
Likely causes
- Oil contamination or sludge jamming the actuator/solenoid
- Wiring shorted to constant 12V (actuator commanded ON constantly)
- Corroded/loose connector at the actuator
- Actuator coil internal failure (stuck magnet or coil short)
- PCM output driver stuck ON (less common)
Fault status
Status
