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
Check DTC.
Is there DTC(s) other than P0111?
YES
Go to applicable DTC(s).

3. IAT sensor signal circuit and ground circuit check
Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C01", "E01" and MAF & IAT sensor connectors.
Check for proper terminal connection to "C01", "E01" and MAF & IAT sensor connectors.
If connections are OK, check the following points.
Resistance of each "B1" and "B2" circuits: less than 1
Resistance of "B1" circuit between MAF & IAT sensor connector and ground: infinity
Resistance between "B1" circuit terminal and each terminal at MAF & IAT sensor connector: infinity
Resistance between "B2" circuit terminal and each terminal at MAF & IAT sensor connector: infinity
Are they in good condition?
YES
Go to Step 4.
NO
Repair or replace defective wire harness.
4. IAT sensor check
