Camshaft Position Sensor B Circuit Low Input (Bank 2)
The camshaft position sensor on bank 2 is sending a signal that's too weak or stuck low, like a dimmer switch stuck at minimum brightness. The engine computer can't properly track the cam timing, which throws off fuel injection and spark timing.
The ECM monitors the voltage signal from the camshaft position sensor B on bank 2, expecting it to toggle between high and low states as the cam rotates. When the voltage stays abnormally low or fails to rise above the minimum threshold, the ECM registers a low-input fault. This prevents proper cam timing synchronization with the crankshaft.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Sensor voltage | 0.5–4.5 volts (oscillating) | Below 0.3 volts or stuck low |
| Signal switching | Clean transitions at cam rotation | No transition or continuous low signal |
Code P0367 is a moderate fault. You can generally drive to a workshop, but avoid long trips or high-load driving (motorway, uphill towing) until it is diagnosed. If the code keeps returning after clearing, or if you notice the symptoms listed above worsening, do not delay professional diagnosis. Many moderate codes have multiple possible root causes — a mechanic with live OBD data can identify the exact fault more efficiently than part-by-part trial and error.
Once the fault is repaired, P0367 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
