Crankshaft Position–Camshaft Position Correlation Error - Lotus Evora Service Notes

Lotus Service Notes
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.
Monitor:
• Continuous
Enable Criteria:
• Engine running (from cranking up to 4 seconds)
Disable Criteria:
• None
Malfunction Criteria:
• Camshaft out of phase with crankshaft > 16 degrees
Potential failure modes:
• Static valve timing is incorrect
• VVT camshaft actuator failure
• VVT control valve stuck open / closed
• VVT control valve filter
Diagnostic Mask:
• The MIL will be illuminated if the faults are present for 2 consecutive trips
