P2094

B Camshaft Position Actuator Control Circuit Low Bank 2

Q: Is it safe to drive with P2094?

For short trips, yes — the engine starts and runs, though it may idle rough or feel down on power. Prolonged driving isn't ideal since valve timing is off, so repair it soon.

Q: Can I just clear P2094?

It returns until the solenoid, wiring, or oil-flow issue is fixed. Check oil condition as part of the diagnosis.

Variable valve timing Generic OBD-II Medium

What it means

P2094 means the PCM detected low voltage on the control circuit for the B (exhaust) camshaft position actuator on bank 2 — the solenoid that adjusts variable valve timing. With the actuator held at its default position the engine typically idles rough and feels down on power, but it still starts and runs. The usual cause is a wiring short, the solenoid itself, or restricted oil flow.

Medium

Can I keep driving? Usually drivable — expect rough idle or reduced power; fix it soon to protect economy and avoid related timing faults.

How to diagnose & fix

Work through it in order

Read freeze-frame data and check for companion cam-actuator codes (P2095, P2090).
Inspect the actuator solenoid connector and wiring for a short to ground or corrosion.
Verify engine oil level and condition; a dirty oil or clogged screen can hobble the phaser solenoid.
Test the solenoid resistance against spec; replace it if faulty. Clear and re-test.
