P0365: Camshaft Position Sensor "B" Circuit (Bank 1)
2 vehicles · 2 makes · $120-$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, and 2010-2018 Kia Forte (LX, EX, SX, Koup, Forte5), with repair costs ranging from $120 to $450.

Diagnostic Tools
This is a powertrain code, so a basic OBD-II reader can read it. These read P0365.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
