Code 7 - Throttle Position (TP) Sensor

  1. Turn ignition off. Remove BACK-UP fuse (7.5-amp) from underhood fuse/relay box for 10 seconds to reset ECM. Retrieve codes. If Code 7 does not appear, problem is intermittent. Inspect for poor or loose connections at throttle position sensor, TCM (if equipped), left and right shock towers, and ECM connectors. Test-drive vehicle and retest.
  2. If MIL is on and indicates Code 7, turn ignition off. Unplug 3-pin connector from throttle position sensor. Turn ignition on. Measure voltage between Yellow/Blue (+) and Green/Blue (-) wire terminals. If voltage is not about 5 volts, go to step 6). If voltage is about 5 volts, turn ignition off. Reconnect sensor wiring. Connect ECM Test Harness (07LAJ-PT3010A ) between ECM and ECM harness. See Figure .
  3. Turn ignition on. Measure voltage between test terminals D11 (+) and D22 (-). Voltage should be about 0.5 volt at closed throttle, and about 4.5 volts at wide open throttle. Transition from 0.5 to 4.5 volts (as throttle is opened) should be smooth. If voltage and operation is correct, temporarily substitute known good ECM, then retest system.
  4. If sensor voltages are not correct on M/T models, go to next step. If sensor voltages are not correct on A/T models, unplug 22-pin connector from Transmission Control Module (TCM). Again measure voltages. If voltages and operation are not correct, go to next step. If voltages and operation are correct, temporarily substitute known good TCM, then retest system.
  5. On all models, replace throttle position sensor or repair Red/Blue wire between ECM terminal D11, TCM (if equipped), and throttle position sensor.
  6. If voltage between Yellow/Blue (+) and Green/Blue (-) wire terminals in step 2) was not about 5 volts, measure voltage between Yellow/Blue wire terminal (+) and body ground. If voltage is about 5 volts, repair open in Green/Blue wire between ECM terminal D22 and throttle position sensor.
  7. If voltage is not about 5 volts, turn ignition off. Connect ECM Test Harness (07LAJ-PT3010A ) between ECM and ECM harness. Turn ignition on. Measure voltage between test terminals D20 (+) and D22 (-). If voltage is about 5 volts, repair open in Yellow/White wire terminal between ECM connector terminal D20 and throttle position sensor. If voltage is not about 5 volts, inspect for short in Yellow/Blue wire. If wire is okay, temporarily substitute known good ECM, then retest system.
