DTC 43: Throttle Position (TP) Sensor
- Check Power Supply
- Turn ignition off. Disconnect TP sensor harness connector. See Fig 1
. Turn ignition on. Measure voltage between TP sensor connector terminal "a" (Red/Yellow wire) and ground. See Fig 2
. If voltage is about 5 volts, go to next step. If voltage is not about 5 volts, repair harness or connectors as necessary.
- Check Ground Circuit
- Turn ignition off. Check continuity between TP sensor connector terminal "c" (Black wire) and engine ground. See Fig 3
. If continuity is present, go to next step. If continuity is not present, repair harness or connectors as necessary.
- Check Input Signal Circuit
- Disconnect ECM harness connector. See Figure
. Check continuity between ECM connector terminal No. 20 and TP sensor connector terminal "b" (White wire). See Figure
and Fig 4
. If continuity is present, go to next step. If continuity is not present, repair harness or connectors as necessary.
- Check Component
- Inspect TP sensor. See I - SYS/COMP TESTS article. Replace TP sensor if necessary and perform FINAL CHECK
in this article. If TP sensor is okay, repair ECM pin terminals or wiring harness connector.
