Probe 2.2L
- Remove air duct from throttle body. Disconnect 3-wire connector at TPS, located at bottom of throttle body assembly. Remove plastic connector shield from male side of TPS connector. Reconnect unshielded connectors to TPS. Use extreme care not to ground the White wire.
- Turn on ignition. Ensure throttle valve is in fully closed position. Using a DVOM, check and record voltage at Red to Black wire. Move DVOM lead and check voltage at White to Black wire. Observe voltage reading. See PROBE 2.2L TPS VOLTAGE SPECIFICATIONS table. If voltage relationship of Red to White wire is not correct, loosen mounting screws and rotate TPS to achieve correct voltage range.
- If White wire voltage cannot be adjusted to specification, TPS must be replaced and adjustment procedure repeated on new TPS. Disconnect negative battery cable and depress brake pedal for at least 2 seconds to eliminate ECA malfunction memory.
