P0365: Camshaft position sensor B circuit fault (bank 1)
Electrical fault in the camshaft sensor or its wiring. Usually the connector, a wire or the sensor, and the car takes longer to start.
| Code | P0365 |
|---|---|
| System | Engine and transmission |
| Group | P03xx, Ignition and misfires |
| Type | Generic: it means the same on every make |
| Can you keep driving? | With care |
What P0365 means
The camshaft sensor tells the ECU which stroke each cylinder is on, so it can inject at the right moment and control variable valve timing if fitted. This code means the sensor’s electrical circuit is not working or the signal is not arriving. Bank 1 is the side of the engine with cylinder 1; on inline engines it is the only bank. Which sensor is "B" is up to each manufacturer (often the intake cam is A and the exhaust cam is B).
Most common causes
- Loose, dirty or corroded sensor connector
- Broken or chafed wire
- No supply to the sensor (fuse or feed wire)
- Failed sensor
- ECU fault (rare)
Symptoms
- Longer cranking before the engine starts
- Less power or slower response
- Slightly rough idle
- Engine warning light on
Can you drive with P0365?
With care You can usually keep driving, as the ECU can manage using the crankshaft sensor, but the engine is down on power and may be hard to start. Get it checked soon.

How to check it
Notice how long it takes to start: if the engine now turns over noticeably longer than before it fires, that is the typical sign of the ECU starting without this sensor.
How to read and clear P0365 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0365 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0365?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0365 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
