Function Explanation (DTC Detection Outline)
• If the rate at which the HO2S output voltage is lowered is slow during fuel cut, a DTC is stored.
Repeatability Verification Procedure
1. Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
2. Verify that OBD-II information (such as freeze frame data) has been obtained and recorded.
3. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC.)
4. Switch the ignition off.
5. Drive the vehicle for 15 min at a speed of 40 km/h {25 mph} or more.
6. Shift to 3rd gear and rapidly accelerate the vehicle to 60 km/h {37 mph}.
7. Release the accelerator pedal and decelerate the vehicle to 40 km/h {25 mph}.
8. Repeat Step 5 to 7 operations above 5 times.
9. Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the freeze frame data/snapshot data.
-
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.
