Camshaft position sensor B is the exhaust camshaft sensor (bank 1 = side with cylinder 1), usually a Hall sensor on the exhaust cam phaser. The engine module holds the signal line at about 5 V and the sensor pulls it to ground with each tooth. P0367 means the line stays low without edges – typically a short to ground of the signal wire or a sensor shorted internally. A code-specific manufacturer description exists only from GM: on the Saab 9-4X 2.8 turbo V6 (LAU) the signal must stay low without pulses for more than 1 s, or 10 s cumulatively, after more than 10 crank revolutions and below 2,520 rpm, and the code follows after two trips; with the sensor disconnected the signal wire should show 4.8–5.2 V. GM's other engines of 2014–2019 and Ford report such faults under P0365. The consequence is as for P0365: exhaust cam timing in its base position, longer cranking.

Likely causes

Signal wire chafed through to ground
Sensor shorted internally
Oil or water in the connector
Engine module

Symptoms

  • Check engine light on
  • Longer cranking before the engine starts
  • Loss of power or rough idle (exhaust cam timing in its base position)
