Diagnosis & Repair
- Disconnect throttle control motor connector. Throttle control motor is located between accelerator cable and throttle body. Using an ohmmeter, measure resistance between throttle control motor connector terminals No. 1 (Green wire) and No. 2 (Red wire). Resistance should be .3-100.0 ohms at 68°F (20°C). If resistance is not as specified, replace throttle control motor. If resistance is as specified, go to next step.
- Visually inspect throttle valve for foreign material. Clean throttle valve as necessary. If throttle valve is clean, replace throttle body.
