P0367 indicates the Powertrain Control Module (PCM) detected a voltage signal from the Camshaft Position Sensor B on Bank 1 that is below the expected range. This sensor monitors camshaft position and timing for engine operation; a low circuit voltage typically points to an electrical issue preventing proper signal communication.
The sensor itself has malfunctioned internally, producing an abnormally low output voltage that the PCM interprets as a circuit fault.
The signal, power, or ground wires are damaged, shorted to ground, or have excessive resistance due to wear, heat damage, or rubbing against engine components.
The sensor connector pins are corroded, bent, or loose, creating high resistance or intermittent connections in the circuit.
The camshaft position sensor signal wire has shorted to chassis ground, pulling the voltage low and triggering the code.
The sensor is not receiving proper reference voltage or ground due to a failed circuit, often from prior wiring issues.
The PCM itself has failed and is incorrectly reading the sensor circuit or not providing proper reference voltage; this is the least likely cause and should be diagnosed only after all other possibilities are ruled out.
Yes. While wiring issues are also common, the sensor itself fails frequently enough that it is typically the first component tested when diagnosing this code.
Almost never. The PCM is the least likely cause of P0367. Most shops and some guides incorrectly recommend PCM replacement, but in the vast majority of cases the fault lies in the sensor, wiring, or connectors.
Driving is not recommended. The camshaft position sensor is critical for proper engine timing and fuel injection. Failure can cause hard starting, stalling, and reduced power, potentially leaving you stranded.
No. The code will remain stored until the underlying fault is repaired and the code is cleared with a scan tool. Disconnecting the battery may also reset learned engine adaptations, potentially causing drivability issues.
