Diesel Governor Control Lever Position Sensor: Description and Operation

Fuel Injection Pump Lever (FIPL) Sensor:

The Fuel Injection Pump Lever (FIPL) sensor is used on vehicles equipped with an automatic transmission. It is bolted to the fuel injection pump and is actuated by the throttle lever.

The FIPL sensor provides an electrical signal, which is proportional to the amount of fuel being delivered, as an input to the Transmission Electronic Control Assembly (TECA). Based on this information, the TECA provides the proper shift scheduling and torque capacity.

Should a malfunction occur in the FIPL sensor circuit, the electrical signal sent to the TECA will be recognized as erroneous. When this out of specification signal is detected, the TECA will provide a high capacity operating mode that protects the transmission from potential damage.
