A Camshaft Position Actuator Control Circuit High Bank 2
What it means
P2093 means the engine computer detected high voltage on the control circuit for the "A" (intake) camshaft position actuator on bank 2 — the variable valve timing (VCT) solenoid that adjusts cam timing. The engine generally still starts and runs, but with the solenoid faulted you may notice rough idle, lost power, or a rattle. Common causes are wiring shorts, a failed solenoid, or dirty oil disrupting VCT operation.
Can I keep driving? Usually yes — the engine typically starts and runs but may idle rough, lose power, or rattle. Repair soon; letting the timing solenoid stay faulted can worsen driveability and economy.
Common symptoms
What you'll notice
- Check-engine light on
- Rough idle or hesitation
- Reduced power and poorer fuel economy
- Ticking or rattle at idle (from a VCT solenoid stuck by oil flow)
Common causes
Most likely first
- High voltage (short to power or open) in the camshaft actuator solenoid control circuitLikely
- Faulty variable camshaft timing (VCT) oil control solenoid on bank 2Common
- Damaged or corroded wiring/connector at the solenoidCommon
- Continuous or restricted oil flow to the VCT actuator (dirty oil, stuck valve)Less often
- Faulty powertrain control module (PCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the bank 2 camshaft actuator solenoid wiring/connector for a short to power or open.
- Check engine oil level and condition — dirty oil is a common cause of VCT solenoid problems.
- Measure the solenoid's resistance against spec and verify it gets the correct control signal.
- Replace the VCT oil control solenoid if faulty; repair any damaged wiring.
- Clear the code and re-test; if the circuit is good, have the PCM diagnosed.
