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) 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.

A factor other than the HO2S can be considered the cause of the malfunction.
•  Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
6
PURPOSE: VERIFY FLUCTUATION OF HO2S INPUT SIGNAL AT START OF FUEL CUT
•  Start the engine and warm it up completely.
•  Access the HO2S_OUT_VOLT PID using the M-MDS.
•  Drive the vehicle under the following conditions.
Warning
•  When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.
•  While performing this step, always operate the vehicle in a safe and lawful manner.
―  After increasing the engine speed to 4,000 rpm, decelerate using engine braking.
