2. DTC: P0113, Intake Air Temperature Sensor Temperature Too High (see Table 1-15)
Table 1-15
S/N Operation Test Results Actions
1
Connect the diagnostic instrument and adapter, and turn
the ignition switch to ON.
Next step
Yes Go to step 5
2
Check the “intake air temperature” as per the data flow.
Does it match with the temperature within the intake pipe
(related to the temperature of the engine at that moment)?
Note: If the temperature is often -40 , open circuit may ℃
occur.
No Next step
Yes Next step
3
Disconnect the intake air temperature sensor from the
harness. Measure the resistance between pin 1# and pin
2# of the sensor with a multimeter. Does the resistance
match with its temperature (refer to relevant part of the
manual)?
No Replace sensor
Yes Go to step 5
4
Disconnect the intake air temperature sensor from the
harness. Measure the voltage between pin 1# and pin 2#
with a multimeter. Is the voltage about 5V?
No Next step
Yes
Repair or replace
harness
5
Check for short to the ground between pin 17#, 40# of the
ECU and the pin 1#, 2# of the sensor with a multimeter.
No Next step
Yes Diagnosis help
6
Start the engine, and keep idle speed. Check the “intake
air temperature” on the diagnostic instrument. At this
moment, the temperature will increase with the rise of the
engine intake air temperature.
No Replace sensor
