Throttle Position Sensor Check
- Disconnect throttle position sensor. Measure continuity between throttle position sensor terminals No. 1 and 2. See Fig 1.
- Continuity should be infinite (open circuit), with throttle valve fully opened. Continuity should be present (less than 2 ohms), with throttle valve fully closed. If continuity is correct, go to WIRING HARNESS CHECK. If continuity is not correct, replace throttle position sensor.
