Camshaft Position Sensor B Circuit Bank 1
What it means
P0365 means the engine computer has detected a fault in the circuit for the 'B' camshaft position sensor on bank 1. This sensor reports camshaft position for fuel and spark timing, so a faulty signal can cause hard starting, rough running, and — on some engines — stalling or a no-start.
Can I keep driving? Often drivable, but a lost cam signal can cause hard starting, stalling, or a no-start on some engines — repair it promptly.

How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the cam-sensor connector and wiring for damage, oil intrusion, or corrosion.
- Check the sensor tip for debris and confirm the reluctor ring is intact.
- Test the sensor's signal, power, and ground while cranking.
- Replace the camshaft position sensor if testing confirms it. Clear and re-test.
