MONITOR DESCRIPTION
These DTCs are stored when there is an open or short in the air fuel ratio sensor (sensor 1) circuit, or the air fuel ratio sensor (sensor 1) output value is abnormal. The voltage of the air fuel ratio sensor (sensor 1) is monitored while the ignition switch is ON, and the impedance (impedance is an electrical term that indicates the difficulty of flow of current) is checked while engine running. If the voltage of the air fuel ratio sensor (sensor 1) is outside the normal range, or the impedance is outside the normal range, the ECM illuminates the MIL and stores a DTC.

CAUTION / NOTICE / HINT
HINT:
-
Sensor 1 refers to the sensor closest to the engine assembly.
-
Sensor 2 refers to the sensor farthest away from the engine assembly.

Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
