P0345: Camshaft Position Sensor Circuit Malfunction (Bank 2)

Most Reported On
P0345 is an OBD-II diagnostic trouble code meaning “Camshaft Position Sensor Circuit Malfunction (Bank 2).” P0345 means the engine computer detected a malfunction in the camshaft position sensor circuit on bank 2 (the cylinder bank not containing cylinder number one). The camshaft position sensor tells the computer where the camshaft is in its rotation, which it uses for precise fuel injection and ignition timing and to manage cylinder identification. When the signal is missing, erratic, or out of range, the computer can't reliably track cam position, which may cause hard starting, rough running, stalling, or a no-start. The fault is usually in the sensor, its wiring, or the connector rather than the camshaft itself. This code is most commonly reported on 2002-2009 GMC Envoy, 2011-2017 Hyundai Elantra, and 2019-2023 Honda Passport, plus 6 other vehicles, with repair costs ranging from $40 to $4,000.
