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.
1. Make sure all electrical items (A/C, audio unit, defogger, lights, etc.) are off.
2. Start the engine with the shift lever in P, parking brake on, and hold the engine speed at 3,000 rpm until the radiator fan comes on.
3. Let the engine idle for 10 minutes with the throttle fully closed.
