Throttle Position Sensor: Testing and Inspection

INSPECTION





1. Apply vacuum to the Throttle Opener.
2. Disconnect the Throttle Position Sensor connector.
3. Insert a thickness gauge between the throttle stop screw and stop lever.








4. Using an ohmmeter measure the resistance between each terminal.

Clearance between Between Resistance
lever and stop screw terminals

0 mm (0 in) VTA - E2 0.28 - 6.4 k ohms
0.35 mm (0.014 in) IDL - E2 0.5 k ohms or less
0.70 mm (0.028 in) IDL - E2 Infinity
Wide open throttle VTA - E2 2.0 - 11.6 k ohms
Always VC - E2 2.7 - 7.7 k ohms

If necessary adjust Throttle Position Sensor and retest.
5. Reconnect the sensor connector.
