1. Warm up the engine to normal operating temperature.
2. Using the M-MDS, monitor the following:
Vehicle speed (PID: VSS)
Engine speed (PID: RPM)
A/F sensor current (PID: O2S11)
3. Drive the vehicle and decelerate the engine speed by releasing the accelerator pedal fully
when the engine speed is 3,000 rpm or more.
4. Verify that the A/F sensor current (PID: O2S11) is 0.25 mA or more while decelerating as
shown in the figure.
