What Does P0367 Mean?
The camshaft position sensor B on bank 2 is reporting a low input signal to the ECM. The voltage is below the minimum expected threshold for normal sensor operation. On DOHC V-configuration engines, this is the exhaust cam sensor on the opposite bank. The engine may exhibit hard starting, rough idle, misfires on the affected bank, and default to degraded fuel injection timing.
Safety Warning
If the engine runs in degraded mode, limit driving to short trips to a repair facility. Without the CMP B bank 2 signal, the ECM cannot properly sequence fuel injection on that bank. Stalling is possible. Some vehicles may not start without this signal.
Common Causes
35%
Failed CMP sensor B on bank 2 with weak or non-functional Hall-effect element
25%
Open circuit or high resistance in the CMP sensor B signal wire on bank 2
20%
Oil-soaked CMP sensor B connector due to bank 2 valve cover gasket leak
10%
Missing or low 5V reference voltage to the CMP sensor B due to shared reference circuit fault
10%
Short to ground on the signal wire between the CMP sensor B and ECM
Diagnostic Steps
1
Measure voltage at the CMP sensor B (bank 2) connector with key on — verify the 5V reference and ground circuit are present and within specification.
2
Disconnect the sensor and check the signal wire for short to ground by measuring resistance from the signal pin to chassis ground — should read infinite (OL).
3
Inspect the CMP sensor B connector on bank 2 for oil contamination — check for visible oil leaking from the valve cover area toward the sensor connector.
4
Measure the signal wire continuity from the CMP sensor B connector to the ECM pin — an open or high-resistance connection will prevent the signal from reaching the ECM.
5
If the 5V reference is missing, check other sensors sharing the same reference circuit — a shorted sensor on the shared line will pull down the reference voltage for all connected sensors.

Typical repair costs for P0367 range from $80 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
