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 information (such as FREEZE FRAME DATA (Mode 2)) has been obtained and recorded.
3.  Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
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 (Mode 2)/snapshot data.
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.
