DTC Confirmation Procedure

WARNING:

If you do not select a suitable route and take proper precautions when performing a road test, an accident can occur.

- Select a level road with no traffic to minimize the risk of accident.
- Perform the test extremely carefully.
- Perform the road test using 2 persons, a driver and an assistant.

NOTE:

- Be sure to troubleshoot first unexpected DTCs previously detected in "DTC Confirmation Procedure".
- Confirm that the following conditions are met in this "DTC Confirmation Procedure".

- DTC P0131, P0132, P0137, P0138 or P2237 is not detected.

1) Warm up engine to normal operating temperature.
2) Drive vehicle at 50 - 60 km/h (31 - 37 mile/h) (engine speed: 1,500 - 3,000 rpm) for 3 min. (Keep throttle valve opening constantly in this step.)

DTC Troubleshooting

1.
Was "Engine and Emission Control System Check" performed?
YES -
Go to Step 2.
NO -
Go to Engine and Emission Control System Check Engine and Emission Control System Check.

2. DTC check

Is there any DTC(s) other than P2195 and P2196?
YES -
Go to troubleshooting for applicable DTC.
NO -
Go to Step 3.

3. A/F sensor signal circuit check

Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C01", "E01" and A/F sensor connectors.
Check for proper terminal connection to "C01", "E01" and A/F sensor connectors.
Check the following points.
- Resistance of "A3" and "A4" circuits: less than 1 ohms
- Resistance between each of "A3" and "A4" circuits and ground: infinity
- Resistance between each of "A3" and "A4" circuit terminals and each terminal at A/F sensor connector: infinity
- Voltage of "A3" and "A4" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")

Are they in good condition?
YES -
Go to Step 4.
NO -
Repair or replace defective wire harness.

4. DTC recheck

Replace A/F sensor. Service and Repair
