HO2S Inspection
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine on).
3. Warm up the engine to normal operating temperature.
4. Access the following PIDs using the M-MDS..
VSS (Vehicle speed)
RPM (Engine speed)
O2S12 (HO2S output voltage)
5. Drive the vehicle and decelerate the engine speed by releasing the accelerator pedal fully when the engine speed is 3,000 rpm or more
.
6. Verify that the HO2S output voltage (PID: O2S12) is 0.3 V or less
while decelerating as shown in the figure.
If not as specified, replace the HO2S..
