System Wiring Diagram

•  Not applicable

Function Explanation (DTC Detection Outline)

•  The PCM detects the oxygen concentration in the exhaust gas based on the A/F sensor signal. The PCM monitors the response speed of the A/F sensor to sudden changes in the oxygen concentration just after fuel cut control starts/ends.
If the response speed of the A/F sensor is delayed, the PCM determines an A/F sensor malfunction and stores a DTC.

Repeatability Verification Procedure

1.  Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
2.  Start the engine and leave it idling for 1 min.
3.  Shift to 3rd gear and drive the vehicle for 10 min at an engine speed of 1,500 rpm or more and a vehicle speed of 50 km/h {31 mph} or more.
Note
•  Match the engine coolant temperature in the recorded freeze frame data/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.
4.  Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the freeze frame data/snapshot data.
