1 vehicles · 1 makes · $180-$450 repair
Most Reported On
P0365 is an OBD-II diagnostic trouble code meaning “Camshaft Position Sensor "B" Circuit (Bank 1).” 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. This code is most commonly reported on 2011-2013 Infiniti M37, with repair costs ranging from $180 to $450.
