Emission Control Information label affixed to the underside of the hood.
Introduction
Some 2009 – 2012 model year RAV4 and 2010 – 2011 model year Camry vehicles equipped with
2AR-FE (non-PZEV) engines may exhibit a MIL ON condition with Diagnostic Trouble Code
(DTC) P0138 (Oxygen Sensor Circuit High Voltage [Bank 1 Sensor 2]). This condition may be
caused by incorrect air fuel ratio sensor response. The Engine Control Module/ECM (SAE Term:
Powertrain Control Module/PCM) logic has been modified to reduce the possibility of this
condition occurring. Follow the Repair Procedure in this bulletin to address this condition.
