Throttle Position Sensor: Testing and Inspection

Throttle Sensor Test:

1. Disconnect throttle sensor connector.
2. Using an ohm meter, check resistance across terminals 1 and 2.
Resistance value should change smoothly, without any glitches, from approximately 2 to approximately 10 ohms as the throttle is moved from idle to Wide Open Throttle (WOT).
Replace sensor if it fails the above test.
