Is there about 5 V?  

YES -Repair open in the wire between APP sensor A and the ECM/PCM (A21), then go to step 20. 

NO -Go to step 25. 

18. Turn the ignition switch OFF.  

19. Replace the APP sensor (see APP SENSOR REPLACEMENT ).  

20. Reconnect all connectors.  

21. Turn the ignition switch ON (II).  

22. Reset the ECM/PCM with the HDS.  

23. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).  

24. Check for Temporary DTCs or DTCs with the HDS. 

If DTC P2122 is indicated?  

YES -Check for poor connections or loose terminals at APP sensor A and the ECM/PCM, then go to step 
1. 

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the 
INDICATED DTCS TROUBLESHOOTING. 

25. Turn the ignition switch OFF.  

26. Reconnect all connectors.  

27. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or 

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).  

28. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P2122 indicated?  

YES -Check for poor connections or loose terminals at APP sensor A and the ECM/PCM, then go to step

1. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE 
ECM/PCM ), then recheck. If the ECM/PCM was substituted, go to step 1. 

NO -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, 
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or 
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING. 

DTC P2123: APP SENSOR A (TP SENSOR D) CIRCUIT HIGH VOLTAGE 

1. Turn the ignition switch ON (II).  

2. Check APP SENSOR A in the DATA LIST with the HDS. 

Is there about 4.85 V or more?  

YES -Go to step 3. 

NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at 
APP sensor A and the ECM/PCM. 

3. Turn the ignition switch OFF.  

4. Disconnect the APP sensor 6P connector.  

5. Turn the ignition switch ON (II).  

6. Measure voltage between APP sensor 6P connector terminals No. 5 and No. 6.

Is there about 5 V?  

YES -Go to step 8. 

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot, and 
review the general troubleshooting information (see GENERAL 
TROUBLESHOOTING INFORMATION ).

8. Turn the ignition switch OFF.  

9. Replace the APP sensor (see APP SENSOR REPLACEMENT ).  

10. Reconnect the APP sensor 6P connector.  

11. Turn the ignition switch ON (II).  

12. Reset the ECM/PCM with the HDS.  

13. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).  

14. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P2123 indicated?  

YES -Check for poor connections or loose terminals at APP sensor A and the ECM/PCM, then go to step 
1. 

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the 
INDICATED DTCS TROUBLESHOOTING.
