P0019-CRANKSHAFT/CAMSHAFT TIMING MISALIGNMENT - BANK 2 SENSOR 2










NOTE: The CMP sensor is a dual read sensor reading both camshafts of it's correlating bank.






For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Engine cranking and Engine running

- Set Condition:
Powertrain Control Module (PCM) detects an error when the camshaft position is out of phase with the crankshaft position. One Trip Fault. Three good trips to turn off the MIL.
