Throttle Position Sensor

Disconnect throttle position sensor connector. On 1.5L, 1.6L and 2.0L, measure resistance between terminals No. 1 (Black wire) and No. 4 (Green/Red wire); on 3.0L, measure resistance between terminals No. 2 (Black wire) and No. 3 (Green/Red wire). See Fig 1 or Fig 2 . Resistance should be 3500-6500 ohms.
On 1.5L, 1.6L and 2.0L, use an analog ohmmeter to measure resistance between terminals No. 1 (Black wire) and No. 3 (Light Green/Yellow wire on 1.5L and 1.6L; Green/White on 2.0L). On 3.0L, measure resistance between terminals No. 2 (Black wire) and No. 4 (Green/Red wire). Slowly operate throttle valve from closed to wide open throttle.
Ensure resistance changes smoothly throughout entire range. Resistance should change from 500 ohms to 3500-6500 ohms. If resistance is not within specification, replace TPS.
