Automatic Transmission

Throttle Position Sensor Resistances:

Throttle Sensor:

1. Disconnect throttle sensor connector.
2. Using an ohm meter, check resistance across terminals A and B.
Resistance value should change smoothly, without any glitches as the throttle is moved from idle to Wide Open Throttle (WOT).
3. Replace sensor if it fails the above test.

Throttle Position Switch Connector:

Closed Throttle Position Switch (idle position)-(A/T model only)
1. Warm up engine sufficiently.
2. Make sure fast idle cam holds cam follower lever released.
3. Disconnect Throttle Position Switch harness connector.
4. Check continuity between terminals 1 and 2.
^ Accelerator pedal released: Continuity
^ Accelerator pedal depressed: No Continuity

Throttle Position Switch Connector:

Wide Open Throttle Position Switch
1. Disconnect Throttle Position Switch harness connector.
2. Check continuity between terminals 2 and 3.
^ Accelerator pedal released: NO Continuity
^ Accelerator pedal depressed: Continuity
