This bulletin applies to 2007-2011 Toyota Camry HV vehicles equipped with a 2AZ-FE engine. An updated throttle body has been released.
This bulletin applies to 2012 Acura RDX models. If the throttle body was recently cleaned or replaced, DTC P2279 (intake air system leak) or P0507 (idle control system rpm higher than expected) and a fluctuating idle exists, it’s likely that the throttle plate is now in a different position from the one that the PCM/ECM had previously learned. To fix the problem, the ECM/PCM must be relearned to the new throttle plate position.
