Exhaust Temperature Sensor
Temperature / Air Pressure Sensor (TBAP)
Crankshaft Position Sensors (CPS)
The 5 tooth crank position sensor picks up all 5 flywheel teeth.
The 2 tooth crank position sensor picks up 2 off set flywheel
teeth.
Both crank position sensors will have a gap to the flywheel pick
up of 0.031" (0.8mm).
These sensors must be in the correct position or the engine will
not run as expected. A sheared flywheel key will cause the
engine to not start or kill if running.
The 2 tooth pick up detects the crank angle and obtains minimal
information of the crank angle when control enters into limp
home mode.
5 tooth pickup is to obtain the following information in
combination with the 2 tooth pickup.
• Judge direction of rotation (forward and backward)
• Ignition advance angle control
• Injector drive angle control
• Excess advance ignition control at reverse
