P0110

COMPONENT DESCRIPTION
The intake air temperature sensor is mounted to the intake air duct. The sensor detects intake air temperature and transmits a signal to the ECM.

The temperature sensing unit uses a thermistor, which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise.

CAUTION: Do not use ECM ground terminals when measuring voltage.
Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals such as the body ground.

On Board Diagnosis Logic:

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE
Perform "Procedure for malfunction A" first.
If 1st trip DTC cannot be confirmed, perform "Procedure for malfunction B".

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.




Procedure for malfunction A

With Consult
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT-II.
3. Wait at least 5 seconds.
4. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

With Generic Scan Tool
Follow the procedure "With CONSULT-II" above.







Procedure for malfunction B

CAUTION: Always drive vehicle at a safe speed.

TESTING CONDITION:
This test may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a road test is expected to be easier, it is unnecessary to lift the vehicle.

With Consult
1. Wait until engine coolant temperature is less than 90 °C (194 °F).
a. Turn ignition switch "ON".
b. Select "DATA MONITOR" mode with CONSULT-II.
c. Check the engine coolant temperature.
d. If the engine coolant temperature is not less than 90 °C (194 °F), turn ignition switch "OFF" and cool down engine.

- Perform the following steps before engine coolant temperature is above 90 °C (194 °F).

2. Turn ignition switch "ON".
3. Select "DATA MONITOR" mode with CONSULT-II.
4. Start engine and turn TCS switch "OFF".
5. Hold vehicle speed more than 70 km/h (43 MPH) for 100 consecutive seconds.
6. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".

OR

With Generic Scan Tool
Follow the procedure "With CONSULT-II" above.
