 HO2S Heater Control Bank 1 Sensor 1 Circuit Short to Battery (P003012,P003013,P101A9E)

DESCRIPTION The air fuel ratio sensor (sensor 1) generates current that corresponds to the actual air fuel ratio. This sensor current is used to provide the ECM with feedback so that it can control the air fuel ratio. The ECM determines the deviation from the stoichiometric air fuel ratio level, and

 Engine Coolant Temperature / Intake Air Temperature Signal Compare Failure (P011B62)

DESCRIPTION The engine has two temperature sensors, an engine coolant temperature sensor and an intake air temperature sensor (for mass air flow meter sub-assembly), to detect temperature while the engine is operating. A thermistor, whose resistance value varies according to the temperature, is buil
