THROTTLE POSITION SENSOR (TPS)
Operation 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.
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 adjusted, the throttle
body assembly must be replaced.
