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.
