ENGINE MANAGEMENT SYSTEM - V8
It is vital that the CKP sensor output wires are not reversed (i.e. the connector is fitted incorrectly) as this will cause
a 3° advance in ignition timing. This happens because the ECM uses the falling edge of the signal waveform as its
reference or timing point for each passing tooth on the reluctor.
Whenever a new crankshaft position sensor is fitted or the flywheel is removed, the adaptive values will have to be
reset, using TestBook.
Should a malfunction of the component occur, the following fault codes may be evident and can be retrieved by
TestBook:
