TechASSIST: Product Support and Information

A Mass Airflow Sensor (MAF) plays a crucial role in engine management by measuring the precise volume of air entering the engine. This data allows the ECU to optimise the air-fuel ratio, ensuring efficient combustion, reduced emissions, and improved drivability.

Why Does It Fail?

MAF sensors typically fail due to:

  • Contamination by oil, dirt, or pollen (often from re-oiled aftermarket air filters)

  • Wiring damage or corrosion at the connector

  • Internal degradation of the sensing element due to age or vibration

  • Moisture ingress or condensation leading to signal distortion

Even small inaccuracies in airflow readings can significantly affect fuel injection, ignition timing, and emissions control.

What Are the Symptoms?

Common symptoms of a failing or faulty MAF sensor include:

  • Hesitation or surging during acceleration

  • Rough idle or stalling, particularly when cold

  • Decreased fuel economy

  • Black smoke from the exhaust under load

  • Check Engine Light (MIL) illuminated

  • Loss of engine power or limp mode activation

Note: A faulty MAF sensor may not always trigger a specific fault code, so live data analysis is often needed to confirm diagnosis.

Fitting Tips

  • Never clean a MAF sensor unless it’s specifically designed for cleaning. Many are non-serviceable.

  • Avoid touching or contaminating the sensing element during installation.

  • Ensure the air filter is clean and the air intake is free of oil residue or debris.

  • Check for air leaks downstream of the MAF sensor that could distort readings.

  • After replacement, clear any fault codes and allow the ECU to relearn idle and fuel trims.
