FUEL SYSTEM

THROTTLE POSITION SENSOR (TPS)

TPS - 325 TPS OVERVIEW
The throttle position sensor (TPS) is used to indicate
throttle plate angle to the ECU. Mounted on the throttle
body and operated directly off the end of the throttle
shaft, the TPS works like a rheostat, varying the voltage
signal to the ECU in direct correlation to the angle of the
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.

CAUTION
The correct position of the throttle body stop screw q 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
1 IAC repositioned or adjusted, the throttle body assembly
must be replaced.
