FUEL SYSTEM

THROTTLE POSITION SENSOR (TPS)

OPERATION OVERVIEW TPS RESISTANCE TESTS
The throttle position sensor (TPS) is used to indicate The TPS is a non-serviceable item. If it is faulty, it must
throttle plate angle to the ECU. Mounted on the throttle be replaced. It can be tested using the following method:
body and operated directly off the end of the throttle With the test leads connected and the meter set to the
shaft, the TPS works like a rheostat, varying the voltage ohms scale, observe the reading at the following pin
signal to the ECU in direct correlation to the angle of the locations of the TPS:
throttle plate. This signal is processed by the ECU and
compared to the internal pre-programmed “maps” to
determine the required fuel and ignition settings for the
amount of engine load.

The correct position of the throttle body stop screw is
established and set at the factory.DO NOT loosen the
throttle body stop screw or alter its position in any
manner. The stop screw controls the air flow calibration
of the throttle body. If the stop screw is repositioned or
