THROTTLE POSITION SENSOR (TPS)

General Information

The throttle position sensor (TPS), mounted to the throttle body,
is used to indicate throttle plate angle to the ECM.
The correct position of the throttle body idle
stop is established and set at the factory.
Do not loosen the throttle body idle stop or
alter the stop position in any fashion. If the
stop is repositioned, the entire throttle body
assembly must be replaced.
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 ECM in direct correlation to the angle of the
throttle plate. This signal is processed by the ECM and
compared to the internal pre-programmed maps to determine the
required fuel and ignition settings for the amount of engine load.

Throttle Position Sensor Test

The throttle position sensor (TPS) is a non-serviceable item. If
it is faulty, it must be replaced. It can be tested using the
following method:

Using an ohmmeter-
With the test leads connected and the meter set to the ohms scale,
observe the reading at the following pin locations of the TPS:
