Troubleshooting High Idle in Honda: Throttle Body TPS Repair

Make: Honda | Model Example: 2012 CR-V | Avg. Mileage: 146747 | Job Number: 502259

Repair Issue:

Power Steering High Pressure Switch – Reset Throttle Position Sensor (TPS)

Customer Concern:

The throttle body was cleaned and now the engine has a high idle and sets a code P0507, the problem can be intermittent and we have tried the idle relearn and it does not help.

Test/Procedure:

1. Follow this procedure using the proper scan tool next to see if the idle is OK.

2. Just cleaned or replaced the throttle body and now you’ve got one or more of these symptoms?

• Fluctuating idle

• MIL on with DTC P2279 (intake air system leak)

• MIL on with P0507 (idle control system RPM higher than expected)

What’s probably happened is the throttle plate is now in a different position from the one the ECM/PCM had learned.

To fix this problem, the ECM/PCM has to relearn the current closed throttle position. Here’s how to do it:

1. Go to INSPECTION MENU in the HDS, and select ETCS TEST.

2. Select TP POSITION CHECK, and clear the throttle position learned value.

3. Turn off the ignition, then, turn it back on.

4. Reset the ECM/PCM.

5. Do the idle learn procedure.

6. Recheck for DTCs. If DTC P2279 or P0507 doesn’t reset, you’re done. If either one does, continue with normal troubleshooting.

Tech Tip:

In some aftermarket scan tools, the reset is found under functional tests.

Important Take-A-Way:

In many cases information found online about idle relearn procedures may be slightly incorrect or be correct but for a slightly different vehicle. The benefit of this archive is that it gives the proper relearn procedure for a technician to perform and in many cases is a simple fix to restore a normal idle after a maintenance service of cleaning the throttle body.
