Introduction

Some 2004 - 2005 model year Camry vehicles equipped with the 2AZ-FE engine (California [PZEV] and Federal [non-PZEV] emissions specification) may experience a limp mode and MIL "ON" condition with DTC P2103, P2111, and/or P2112. The throttle body hose has been modified to address this condition on 2004 PZEV vehicles. The throttle body assembly has been modified to eliminate the throttle body hose on 2004 non-PZEV and all 2005 model year vehicles to address this condition.





NOTE

When these DTCs are stored, the Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) enters LIMP MODE or FAIL SAFE where the ECM cuts off current to the throttle control motor. The throttle control valve returns to a predetermined opening angle (approximately 16 degrees) by the force of the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing in accordance with the accelerator pedal opening angle to enable the vehicle to continue at a minimal speed. If the accelerator pedal is depressed firmly and slowly, the vehicle can be driven slowly.
