- Turn ignition on. Check TPS output voltage at sensor wiring harness center terminal. At idle, output voltage should be greater than .2 volt.
- Gradually open throttle plate. Output voltage should gradually increase as throttle plate is opened. At wide open throttle, output voltage must be less than 4.8 volts.
- If voltages are not as specified, make sure 5-volt input and ground circuits between TPS and engine controller are okay. Repair circuits, if necessary. If TPS output voltages are still not as specified, replace TPS. Adjustment is not required or possible.
