Crankshaft Position–Camshaft Position Correlation Error
P0016 Crankshaft position – camshaft position correlation – bank 1 sensor A (Inlet)
P0017 Crankshaft position – camshaft position correlation – bank 1 sensor B (Exhaust)
P0018 Crankshaft position – camshaft position correlation – bank 2 sensor A (Inlet)
P0019 Crankshaft position – camshaft position correlation – bank 2 sensor B (Exhaust)
Description
The crankshaft position sensor is used to identify engine position and speed via a pole wheel mounted on the
front end of the crankshaft. The camshaft position sensor is used to determine camshaft position from a three
vane reluctor on the rear end of the inlet and exhaust camshaft. Fault codes P0016, P0017, P0018, P0019
indicate a mechanical timing error such as incorrectly set, or 'jumped' cam timing.
