Honda Element. Manual - part 456

 

 

YES -Check for poor connections or loose terminals at APP sensor B 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 P2128: APP SENSOR B (TP SENSOR E) CIRCUIT HIGH VOLTAGE

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

Is there about 4.0 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 B 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. 1 and No. 2.

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 P2128 indicated?  

YES -Check for poor connections or loose terminals at APP sensor B 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

15. Turn the ignition switch OFF.  

16. Reconnect all connectors.

DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING

DTC P2135: TP SENSOR A/B INCORRECT VOLTAGE CORRELATION 

1. Turn the ignition switch ON (II).  

2. Clear the DTC with the HDS.  

3. Do the ETCS TEST in the INSPECTION MENU with the HDS.  

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

Is DTC P2135 indicated?  

YES -Go to step 5. 

NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at 
the throttle body and the throttle actuator control module. 

5. Turn the ignition switch OFF.  

6. Disconnect the intake air duct from the throttle body.  

7. Turn the ignition switch ON (II).  

8. Visually check the throttle valve operation while you clear the DTC with the HDS. 

Does the valve temporarily move to its fully closed position?  

YES -Go to step 14. 

NO -Go to step 9. 

9. Turn the ignition switch OFF.  

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.
