Throttle Position Sensor: Testing and Inspection

Throttle Position Sensor Connector:

1. Turn ignition switch to "OFF".
2. Disconnect throttle sensor connector.
3. Measure resistance between throttle sensor connector terminals.

Terminal/Specified value
No. 1 - No.3/5 ohms

4. Measure resistance between terminals while slowly opening throttle valve from the "close" position.

Terminal/Specified value
No. 2 - No. 3/10 - 12 k ohms [Fully close]
No. 2 - No. 3/3 - 5 k ohms [Fully open]
Ensure resistance increases in response to throttle valve opening.
