TechASSIST: Product Support and Information

The Air Intake Temperature (IAT) Sensor is a critical component within the engine management system. It measures the temperature of the air entering the engine, allowing the ECU to calculate the correct air-fuel mixture, ignition timing and emissions control strategies.

Accurate intake air temperature data helps optimise engine performance, fuel efficiency and emissions compliance across a wide range of operating conditions.

Why Does It Fail?

Intake air temperature sensors operate in a demanding environment and can fail for a number of reasons, including:

  • Heat-related deterioration affecting the sensor element and internal electronics over time.
  • Contamination from oil vapour, dirt or carbon deposits, reducing measurement accuracy.
  • Moisture ingress causing corrosion of the sensor or electrical connector.
  • Wiring or connector faults resulting in intermittent or incorrect sensor signals.
  • Physical damage caused during servicing, maintenance or component replacement.

What Are the Symptoms?

When an intake air temperature sensor fails or provides inaccurate readings, common symptoms may include:

  • Hard starting, particularly in cold weather conditions.
  • Poor throttle response or hesitation during acceleration.
  • Reduced fuel economy caused by incorrect fuel mixture calculations.
  • Increased exhaust emissions and reduced combustion efficiency.
  • Illuminated Engine Management Light (MIL) accompanied by diagnostic fault codes.
  • Reduced engine performance caused by inaccurate air temperature data being supplied to the ECU.

Fitting Tips

  • Inspect the sensor connector and wiring for signs of corrosion, damage or poor connections before replacement.
  • Handle the sensor carefully and avoid contaminating the sensing element during installation.
  • Check for intake system leaks that could affect sensor readings and overall engine performance.
  • Clear any stored fault codes and follow the vehicle manufacturer's relearn procedure where required.
  • Verify live data readings using a diagnostic tool to confirm correct operation after installation.
  • Allow the engine to reach operating temperature and check for stable sensor values under normal running conditions.
