Causes
- Damaged or shorted wiring in the cam actuator control circuit (short to battery voltage)
- Poor or corroded connector/terminal at the actuator or PCM
- Faulty camshaft position actuator/solenoid (internal short or stuck)
- Low or contaminated engine oil causing actuator mechanical sticking
- Faulty PCM (rare)
- Blown or incorrect fuse or power supply issue to VVT circuitry
Symptoms
- Check Engine Light (MIL) illuminated
- Reduced engine performance or poor throttle response
- Rough idle, hesitation, or occasional misfire
- Degraded fuel economy
- Engine may run noisier or feel less smooth during acceleration
What to check
- Read freeze frame and stored data (confirm Bank 2 and B actuator circuit)
- Scan live data: camshaft position, commanded actuator duty, and actual response
- Visual inspection of wiring and connectors for damage, corrosion, pin push-out
- Check engine oil level and condition (dirty/thick oil can impede VVT)
- Measure voltage at actuator connector with key ON / engine OFF and during cranking
- Measure resistance of the actuator solenoid (compare to spec)
Signal parameters
- Supply voltage to actuator: approx. battery voltage (~11.5–14.5 V with engine running)
- Control signal: PCM typically switches ground or provides PWM — voltage may vary 0–12 V depending on duty
- Expected solenoid resistance (generic): commonly in the range ~6–30 ohms (consult vehicle spec)
- If open circuit: infinite/very high resistance. If short to battery: near 0 ohms between circuit and battery
Diagnostic algorithm
- Retrieve full code list, freeze frame, and live data. Confirm code P2095 is current and relates to Bank 2 B actuator.
- Visually inspect the cam actuator wiring harness and connectors on Bank 2 for damage, pin corrosion, or pushed-out terminals. Repair as needed.
- Check engine oil level and condition; top or change oil if low or contaminated. If sludge is present, consider VVT cleaning or service.
- Backprobe the actuator connector: with ignition ON (engine OFF) check for battery feed at the power pin and for the PCM control signal on the control pin. Note voltages.
- Measure solenoid coil resistance at the connector (unplugged). Compare to factory spec; replace solenoid if out of range, shorted, or open.
- Wiggle-test wiring while monitoring live data for intermittent changes. Repair broken/chafed wires or poor connections.
- If power and ground are present and solenoid checks good but circuit still shows high, check for shorts to battery on the control side (pin-to-battery voltage).
- If wiring and actuator are good, check PCM control using an oscilloscope (verify expected PWM pattern). If PCM outputs abnormal voltage and wiring/actuator verified good, consider PCM replacement only after thorough verification.
- Clear codes and road-test to confirm repair. Re-scan after warm-up and repeated cycles to confirm no return.
Likely causes
- Wiring shorted to battery voltage at the actuator connector
- Corroded connector or poor ground/power feed
- Failed camshaft actuator solenoid
- Oil sludge or low oil causing actuator to stick
Fault status
Status
Camshaft position actuator control circuit high — Bank 2, B actuator. PCM detects high voltage/abnormal condition on the VVT actuator control circuit causing improper cam timing control.
Repair difficulty: Medium
Diagnostic time: 1-3 hours
