P0365 on Buick
Camshaft Position Sensor "B" Circuit (Bank 1)
P0365 on Buick vehicles indicates camshaft position sensor "b" circuit (bank 1). Au7o has documented this code across 1 Buick model — most commonly on Encore. This code means the engine computer detected a problem in the circuit for the 'B' camshaft position sensor on Bank 1 (typically the exhaust camshaft, or the second cam sensor on that bank). This sensor reports camshaft position so the PCM can correctly time fuel injection, ignition, and variable valve timing. A circuit fault here can cause hard starting, rough running, reduced power, or affect variable valve timing. While usually not an immediate breakdown risk, it should be addressed to avoid driveability and timing-related issues.
Common Causes of P0365
- •Faulty camshaft position sensor (Bank 1, sensor B)
- •Damaged wiring or connector at the sensor
- •Open or short in the sensor circuit
- •Corroded or loose connector pins
- •Reluctor/tone ring damage on the camshaft
- •Failing PCM (less common)
P0365 on Buick by Model
Buick Encore(1 issue)
- Exhaust Camshaft Reluctor Can Move Out of Phase (21-NA-268)2016-2022
GM Bulletin 21-NA-268 applies to 2016-2022 Buick Encore vehicles with the 1.4L LE2 engine. An exhaust-camshaft reluctor that moves out of phase can cause an extended crank or crank/no-start condition, illuminate the MIL and, in some cases, increase brake-pedal effort. The vacuum-pump drive lugs may also be damaged.

What does P0365 mean on Buick?▼
P0365 stands for "Camshaft Position Sensor "B" Circuit (Bank 1)."
