Disconnect electrical connectors.
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.

Install TPS 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.
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.
