- Remove the TPS attaching screw assemblies and retainer, (if applicable).
- Remove TPS from throttle body assembly.
NOTE: The TPS is an electrical component and must not be soaked in any liquid cleaner or solvent, as damage may result.

INSTALLATION:

- Install TPS, with seal, to throttle body assembly, while lining up TPS lever with TPS drive lever on throttle body.
- Install the two attaching screw assemblies. Tighten screw assemblies to 2.0 Nm (18.0 lb-in).
- Install electrical connector to TPS.

- 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.
