- Turn ignition on. Check TPS output voltage at center terminal. With throttle closed, voltage should be .20-1.5 volts.
- Slowly open throttle. Voltage should gradually increase to 4.1-4.8 volts at wide open throttle. If not, make sure 5-volt input and ground circuits between TPS and engine controller are okay. If TPS output voltages are not as described, replace TPS. TPS is not adjustable.
