TechASSIST: Product Support and Information

The Air Intake Temperature Sensor plays a key role in engine management by measuring the temperature of air entering the intake manifold. This information allows the ECU to optimise the air-fuel mixture, ignition timing, and emissions control systems for improved performance, efficiency, and compliance.

Why Does It Fail?

Intake air temperature sensors typically fail due to:

  • Heat and age-related degradation of internal electronics

  • Contamination from oil, dust, or carbon deposits

  • Moisture ingress or corrosion at the connector or sensor tip
    In some cases, damage may also result from incorrect handling during servicing or retrofit.

What Are the Symptoms?

When an IAT sensor fails or provides inaccurate readings, you may observe:

  • Hard or delayed starting, especially in cold conditions

  • Poor throttle response or engine hesitation

  • Reduced fuel efficiency

  • Increased emissions

  • Check Engine Light (MIL) illuminated
    Incorrect readings can lead the ECU to enrich or lean the mixture improperly, affecting both performance and emissions.

Fitting Tips

  • Always inspect the sensor connector and wiring harness for signs of corrosion or damage before replacement.

  • Avoid touching the sensing element with bare hands; oils can interfere with readings.

  • If integrated into the MAF sensor housing, ensure the entire unit is replaced if non-serviceable.

  • Clear any stored fault codes and perform an ECU reset if required to allow the system to relearn ambient inputs.

  • Allow the vehicle to idle and reach normal operating temperature to verify proper data input post-installation.
