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

Is DTC P2135 indicated?  

YES -Check for poor connections or loose terminals at the throttle body and the throttle actuator control 
module, then go to step 1 

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

1. Turn the ignition switch ON (II).  

2. Clear the DTC with the HDS.  

3. Press the accelerator pedal to the floor.  

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

Is DTC P2138 indicated?  

YES -Go to step 5. 

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

5. Check APP SENSOR A and APP SENSOR B in the DATA LIST with the HDS. 

Are they the same voltage?  

NOTE:

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

step 1. 

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

21. Reconnect all connectors.  

22. 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 ).  

23. Turn the ignition switch OFF.  

24. Turn the ignition switch ON (II).  

25. Press the accelerator pedal to the floor.  

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

Is DTC P2138 indicated?  

YES -Check for poor connections or loose terminals at the APP sensor and the ECM/PCM. If the 
ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE 
ECM/PCM ), then go to step 23. 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 P2176: THROTTLE ACTUATOR CONTROL SYSTEM IDLE POSITION NOT LEARNED 

1. Turn the ignition switch ON (II).  

2. Clear the DTC with the HDS.  

3. Turn the ignition switch OFF.  

4. Turn the ignition switch ON (II), and wait 10 seconds.  

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

Is DTC P2176 indicated?  

CAUTION: Do not insert your fingers into the installed throttle body when you turn 

the ignition switch ON (II) or while the ignition switch is ON (II). If you do, 
you will seriously injure your fingers if the throttle valve is activated.

NOTE:



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



If DTC P2135 is stored at the same time as DTC P2176, troubleshoot DTC 
P2135 first, then recheck for DTC P2176.
