APP Sensor Signal Inspection: Inspection
NOTE:
- This procedure checks the APP sensor in its fully closed position. In any other position, the APP sensor stores DTCs which are covered in other troubleshooting procedures.
- Check for Pending or Confirmed DTCs with the HDS before doing this procedure. If any DTCs are indicated, troubleshoot them first, then do this procedure.
- Press the accelerator pedal several times, to check its operation. If it does not operate smoothly, check the pedal. If you find a problem, replace the accelerator pedal module .
- HDS - Connect
1. Turn the vehicle to the ON mode. 2. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting - Refer to: DLC Circuit Troubleshooting(PGM-FI System) (2014 2015), or DLC Circuit Troubleshooting(PGM-FI System) (2017)
.
- APP Sensor Signal - Inspect
1. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS. - If it is 0 %, the APP sensor is OK.
- If it is not 0 %, update the PCM if it does not have the latest software , or substitute a known-good PCM - Refer to: PCM Removal and Installation (2014 2015), or PCM Removal and Installation (2017) , then go to step 2.
