|
|
|
Drive cycle
|
• 2
|
|
|

|
|
|

|
• A/F sensor
|
|
|
Fail-safe function
|
• Fixes duty value of A/F sensor heater
• Stops fuel feedback control of A/F sensor
|
|
|
Vehicle status when DTCs are output
|
• Not applicable
|
|
|
Possible cause
|
• A/F sensor signal malfunction
• A/F sensor deterioration
• A/F sensor heater malfunction
• PCM malfunction
|
|
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.
