Throttle Position Sensor: Testing and Inspection

Fig. 153 Throttle Sensor Inspection:

1. Disconnect throttle sensor connector.
2. Using an ohm meter, check resistance across terminals e and f.
Resistance value should change smoothly, without any glitches, from approximately 1 to approximately 9 ohms as the throttle is moved from idle to WOT.
Replace sensor if it fails the above test.
