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
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.
