System Wiring Diagram

• Not applicable



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-II 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.

Inspection

Results

Action

1
PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
• Verify related Service Bulletins, on-line repair information, or Service Information availability.
• Is any related Information available?
Yes
Perform repair or diagnosis according to the available information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the freeze frame data/snapshot data and diagnostic monitoring test results (A/F sensor, HO2S related).

Note
• Recording can be facilitated using the screen capture function of the PC.
Go to the next step.
3
PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY DTC RELATED TO A/F SENSOR RESPONSIVENESS
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Are any of the following DTCs displayed?
― P0133:00
Yes
Go to the next step.
No
Go to Step 6.
4
PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY DTC RELATED TO PURGE SOLENOID VALVE
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Are any of the following DTCs displayed?
― P0443:00
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
Go to the next step.
No
Go to the next step.
5
PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY DTC OCCURRING FROM FUEL SYSTEM RELATED PART
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
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. (See PID/DATA MONITOR INSPECTION.)
• 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.
• Can a fluctuation in the displayed PID value be verified?
Yes
Go to Troubleshooting Diagnostic Procedure to perform the repair completion verification.
• If a malfunction occurs, perform diagnosis from Step 1 of the malfunction diagnostic procedure.
No
HO2S signal can be considered the cause.
• Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 4.
