P0365

Camshaft Position Sensor B Circuit Bank 1

The engine computer is not getting the correct signal from camshaft position sensor B on bank 1. This can cause hard starting, rough running, misfires, and poor fuel economy. The problem may be the sensor, wiring, connector, or a timing-related issue.

Severity3/5 Moderate
Can I drive?⚠ With caution

You may be able to drive short distances, but the engine can run poorly or stall. If the check engine light is flashing, the engine is misfiring badly, or the car stalls, stop driving and repair it.

FAQ

Can I keep driving with P0365?

You can sometimes drive short distances, but it is not recommended if the engine runs rough, stalls, or misfires. Fix it soon to avoid getting stranded or causing more damage.

Is P0365 always a bad camshaft sensor?

No. Wiring, connectors, oil contamination, timing problems, and PCM issues can also cause this code.

What bank 1 means?

Bank 1 is the side of the engine that contains cylinder number 1.

Will clearing the code fix it?

Clearing the code only resets the warning light. If the fault is still present, the code will return.
