Throttle Position Sensor: Service and Repair

Removing TP Sensor:

Comp. Loc:

Measuring TP Sensor Resistance:

Inserting Feeler Gauge:

REMOVE OR DISCONNECT
1. Negative (-) battery cable.
2. Throttle Position (TP) sensor electrical connector.
3. Two bolts and TP sensor from throttle body.

INSTALL OR CONNECT
1. Align TP sensor onto throttle body so that sensor pickup lever can engage with throttle body lever; secure with two bolts. Do not tighten fully.

Adjust
A. Connect a DVOM to TP sensor connector terminal "1" to "2" (TP sensor side). Measure resistance.

NOTICE: Throttle valve must be closed.

B. Insert a 0.65 mm (0.026 inch) feeler gage between throttle stop screw and throttle lever and with retaining screws loosely installed, turn TP sensor fully counterclockwise, then slowly clockwise gradually to find the position where ohmmeter reading changes from continuity to no continuity. Tighten TP sensor bolts to 2.5 - 4.5 Nm (22.8 - 38.4 lb. in.).
C. Remove feeler gage. DVOM should still indicate continuity.
D. Insert 0.8 mm (0.032 inch) feeler gage between throttle stop screw and throttle lever. DVOM should now indicate an open circuit.
E. Insert 0.5 mm (0.020 inch) feeler gage between throttle stop screw and throttle lever. DVOM should indicated continuity. If steps C, D or E are unsatisfactory, return to step A and repeat entire procedure.

2. TP sensor electrical connector
3. Negative (-) battery cable. Tighten Negative (-) battery cable-to-negative (-) battery terminal retainer to 15 Nm (11 lb. ft.).
