TPS (throttle position Sensor) is a variable potentiometer! Is is connected to the throttle shaft on the throttle body. The ECM/PCM (computer) uses the voltage from the TPS to determine fuel delivery based on the angle of the throttle shaft or valve (driver demand)
A loose or broken TPS can cause an unstable idle or intermittent bursts of fuel from the fuel injectors, because the ECM/PCM is fooled into thinking the throttle is moving.
The throttle position switch (tps) is located on the throttle body.
You can not change just the TPS for this car. You have to replace the entire throttle body.
A TPS is a variable resistor that tells the engine computer the absolute throttle opening percentage. A switch tells the system when the throttle is wide open for enrichment purposes.
The TPS (throttle position switch) is attached directly accross from where the throttle cable attaches to the throttle body. It is held on with 2 torx type screws.
The TPS is part of the throttle body and is only serviced with the throttle body.The TPS is part of the throttle body and is only serviced with the throttle body.
GM. did not start using TPS / THROTTLE POSITION SENSORS until they switch to the fuel injection fuel system. Your truck has a carburetor, TPS was not used on that type of fuel system.

Disconnect the negative battery cableRemove the air intake duct and disconnect the TPS and wide open/closed throttle switch electrical connectorsRemove the two retaining screws and separate the TPS from the throttle body
The tps is on the throttle body opposite of where the cables attach.The tps is on the throttle body opposite of where the cables attach.
Your TPS will be located on the throttle body.
Throttle Position Sensor ( located on the throttle body )
Throttle Position Sensor/Switch A Circuit Low Input You need to test the wiring to the TPS, check the computer, and maybe replace the tps
