Function Explanation (DTC Detection Outline)

P013A:00

If the rate at which the HO2S output voltage is lowered is slow during fuel cut, a DTC is stored.

P013B:00

Repeatability Verification Procedure

Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
Verify that OBD-II information (such as FREEZE FRAME DATA) has been obtained and recorded.
Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.0)].)
Switch the ignition off.
Drive the vehicle for 15 min at a speed of 40 km/h {25 mph} or more.
Shift to 3rd gear and rapidly accelerate the vehicle to 60 km/h {37 mph}.
Release the accelerator pedal and decelerate the vehicle to 40 km/h {25 mph}.
Repeat Step 5 to 7 operations above 5 times.
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.
