Function Explanation (DTC Detection Outline)

•  If there is communication error between the A/F signal control driver and the CPU, the PCM 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.
Note
•  Match the engine coolant temperature in the recorded FREEZE FRAME DATA (Mode 2)/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.
3.  Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the FREEZE FRAME DATA (Mode 2)/snapshot data.

PID Item/Simulation Item Used In Diagnosis

•  Not applicable

Troubleshooting Diagnostic Procedure
