P0367 — Camshaft Position Sensor B Circuit Low (Bank 1)
Moderate severityWhat it means
P0367 is stored when the engine control unit sees a fault involving the camshaft position sensor B circuit on bank 1. Sensor B is the second camshaft position sensor on bank 1 (for example on the exhaust cam of a dual-VVT engine); the control unit uses it for valve-timing control and sequencing. A “low” reading means the signal is stuck near the bottom of its range, which usually points to a short to ground or an internally failed sensor.
Common symptoms
- The live reading sits abnormally low or at zero
- Hard starting or rough running
- Loss of power or VVT-related codes
- Possible stalling
Likely causes
- Signal wire shorted to ground
- Internally failed sensor pulling the signal low
- A faulty camshaft position sensor B
- A wiring/connector fault or a worn tone ring
What to check first
- Compare the live signal against a known-good range and check for a short to ground
- Inspect the sensor B connector and wiring
- Check for cam/crank correlation codes and timing noise
Can you keep driving?
May cause hard starting or stalling; if it runs poorly, avoid driving until it is checked.
Frequently asked questions
What is the most common cause of P0367?
The most likely cause is: Signal wire shorted to ground. Several other faults can set P0367 as well, so confirm the real cause with live data and the checks above before replacing any parts.
Can I just clear P0367 and keep driving?
Clearing P0367 with an OBD2 scanner turns the warning light off, but if the underlying fault has not been repaired the code will usually come back within a few drive cycles. Fix the cause first, then clear the code to confirm the repair worked.
How serious is P0367?
P0367 is a moderate-severity code. The car is often still drivable, but have it diagnosed soon — the underlying problem can get worse and it may fail an emissions test.
