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

1. Turn the ignition switch ON (II).

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.

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 ).

Is there about 5 V?

YES -Repair open in the wire between APP sensor B and the ECM/PCM (A23), then go to step 10.

NO -Go to step 15.

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 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.

17. 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 ).

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

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.

NOTE:

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

Is there continuity?

YES -Go to step 12.

NO -Substitute a known-good throttle actuator control module (see THROTTLE ACTUATOR
CONTROL MODULE REPLACEMENT ), then go to step 16 and recheck. If DTC P2135 is not
indicated, replace the original throttle actuator control module (see THROTTLE ACTUATOR
CONTROL MODULE REPLACEMENT ), then go to step 16.
