P0113 Code: Intake Air Temperature Sensor 1 Circuit High
P0113 means the intake air temperature signal is higher than expected, often from an open circuit or sensor issue. Learn the common symptoms, causes, severity, and typical repair costs.
The P0113 code means the intake air temperature signal is higher than expected, often from an open circuit or sensor issue. It is stored when the engine computer sees a signal or operating condition outside the expected range.
Air and fuel metering codes point to fuel mixture, intake sensor, oxygen sensor, or temperature data problems. The right fix depends on live data, freeze-frame information, service history, and whether other codes are present.
Symptoms
- Check engine light
- Hard starting in some weather
- Poor fuel economy
- Hesitation
- Rough idle
- Sometimes no noticeable symptoms
Common Causes
- Disconnected IAT sensor
- Failed intake air temperature sensor
- Damaged wiring
- Corroded connector
- Sensor contaminated by oil or debris
- Air intake modification or poor sensor fitment
Severity
Low to moderate. The car may run, but incorrect air temperature data can affect fuel mixture and drivability.
Typical Repair Costs
$50 to $300
- The lower end usually covers inspection, cleaning, wiring repair, or a simple sensor replacement.
- The higher end applies when parts are hard to access or when the code is caused by a larger mechanical, emissions, or transmission problem.
- Always diagnose before replacing parts, because one code can be triggered by several related systems.
Frequently Asked Questions
What does code P0113 mean?
P0113 means the intake air temperature signal is higher than expected, often from an open circuit or sensor issue. The exact cause should be confirmed with diagnostic data before replacing parts.
Can I drive with a P0113 code?
It depends on symptoms. If the car runs poorly, overheats, stalls, shifts harshly, or the check engine light flashes, limit driving and diagnose it promptly.
What is the most common fix for P0113?
Common fixes include addressing disconnected iat sensor, failed intake air temperature sensor, damaged wiring, but testing is needed to avoid replacing the wrong part.
