Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle. No comparison between manufacturers or models is implied. All trademarks belong to their respective owners; no affiliation or endorsement is implied.
Common symptoms
What you'll notice
- Inspect and clean the intake air temperature (IAT) sensor for any debris or dirt that may be affecting its accuracy.
- Check the wiring connections of the IAT sensor and ensure they are securely connected without any damages or loose connections.
- Perform a scan tool test to check the IAT sensor readings and compare them with the actual temperature to identify any discrepancies.
- Replace the intake air temperature sensor if it is found to be faulty or not responding correctly to temperature changes.
- Inspect the intake air duct and ensure there are no leaks or obstructions that may affect the accuracy of the IAT sensor readings.
Common causes
Most likely first
- Faulty intake air temperature sensor
- Wiring or connection issue with the intake air temperature sensor
- Faulty engine control module (ECM)
- Air intake leak or vacuum leak
- Restricted air flow to the intake manifold
How to diagnose & fix

- Check Engine Light (Malfunction Indicator Lamp) is illuminated
- Engine running rough or misfiring
