WSG-1068 ENGINE CONTROLS
Crankshaft Position (CKP) Sensor
The Crankshaft Position (CKP) Sensor provides a
signal used by the Engine Control Module (GCP) to
calculate the ignition sequence. The sensor initiates the
reference pulses which the GCP uses to calculate RPM
and crankshaft position.
Camshaft Position (CMP) Sensor
The Camshaft Position (CMP) Sensor uses a variable
reluctor sensor to detect camshaft position. The CMP
signal is created as piston #1 is a pre-determined
number of degrees after top dead center on the power
stroke.
The Camshaft Position (CMP) Sensor sends a CMP
signal to the GCP. The GCP uses this signal as a “sync
pulse” to trigger the injectors in the proper sequence.
The GCP uses the CMP signal to indicate the position
of the #1 piston during its power stroke. The CMP uses
a Hall Effect sensor to measure piston position. This
allows the GCP to calculate true sequential fuel
injection (SFI) mode of operation. If the GCP detects an
incorrect CMP signal while the engine is running, DTC
245 will set.
If the CMP signal is lost while the engine is running, the
fuel injection system will shift to a calculated sequential
fuel injection mode based on the last fuel injection
pulse, and the engine will continue to run. As long as the
fault (DTC 244) is present, the engine can be restarted.
It will run in the previously established injection
sequence.
