P0367 — Camshaft Position Sensor B Circuit Low Bank 1

Generic OBD-II · all makesPowertrain (engine & transmission)

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.

Symptoms

What causes it — most likely first

1. Failed camshaft position sensor

The sensor itself has malfunctioned internally, producing an abnormally low output voltage that the PCM interprets as a circuit fault.

2. Wiring harness damage

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.

3. Corroded or damaged connector

The sensor connector pins are corroded, bent, or loose, creating high resistance or intermittent connections in the circuit.

4. Short to ground in signal circuit

The camshaft position sensor signal wire has shorted to chassis ground, pulling the voltage low and triggering the code.

5. Loss of sensor ground or power

The sensor is not receiving proper reference voltage or ground due to a failed circuit, often from prior wiring issues.

6. PCM/ECM failure (rare)

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.

How it's diagnosed

  1. Connect an OBD-II scan tool, record the P0367 code and any freeze frame data, and check for additional related codes such as sensor circuit power issues.
  2. Locate the Camshaft Position Sensor B on Bank 1 (consult vehicle-specific repair information for exact location, typically near the cylinder head).
  3. Perform a visual inspection of the sensor, wiring, and connector for obvious damage, corrosion, chafing, or disconnected plugs.
  4. With key on and engine off, back-probe the sensor connector to check for proper reference voltage (typically 5V) and ground circuit integrity.
  5. Test the sensor output signal using a multimeter or oscilloscope while cranking the engine to verify the signal changes appropriately.
  6. Check the wiring harness for shorts to ground or open circuits using a continuity tester, and verify all related fuses and relay circuits.

Frequently asked

Is the camshaft position sensor the most common cause of P0367?

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.

Do I need to replace the PCM for 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.

Can I still drive my vehicle with P0367?

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.

Will this code clear itself if I disconnect the battery?

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.
