Our emissions expert has put together the following information about the P0113 code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
Trouble Code:
P0113 – Intake Air Temperature Circuit High Input
P0113 Code Definition:
The Intake Air Temperature Sensor converts the air temperature into a voltage that is high when the Intake Air is cold and low as the engine warms up. P0113 indicates a high voltage input from the Intake Air Temperature to the Powertrain Control Module.
Symptoms:
- Check Engine Light will illuminate
- In many cases, no abnormal symptoms may be noticed
- In some cases, the engine may be hard starting and/or get poor fuel economy
Possible Problems:
- Defective Intake Air Temperature Sensor
- Dirty air filter
- Defective Mass Air Flow Sensor
- Faulty or corroded Intake Air Temperature wiring or connections
Possible Misdiagnoses
- Intake Air Temperature Sensor is replaced when the real cause is a dirty air filter
- Intake Air Temperature Sensor is replaced when the real cause is a poor connection or chafed wiring
