Throttle Position Sensor: Service and Repair

NOTE
Since Throttle Position Sensor (TPS) configurations can be mounted interchangeably, be sure to order the correct one for your engine with identical part number of the one being replaced.

Throttle Position (TP) Sensor:

REMOVE/DISCONNECT
- Electrical connectors.
- TPS attaching screw assemblies and retainer, (if applicable).
- TPS from throttle body assembly.

NOTE Do NOT immerse in any type of liquid solvent or cleaner, as damage may occur.

INSTALL/CONNECT
- With throttle valve in normally closed position, install TPS on throttle shaft with seal and rotate counter clockwise to align mounting hole.
- Two attaching screw assemblies. Tighten screw assemblies to 2.0 Nm (18.0 lb-in).
- Electrical connector to TPS.
- Check for TPS output as follows:
- Connect an ALDL scanner to read TPS output voltage.
- With ignition "ON" and engine stopped, TPS voltage should be less than 1.25 volts. If more than 1.25 volts, replace TPS.
