Mass air flow sensors – choosing the correct part

Mass air flow sensors measure air entering the engine to help determine fuel delivery. Models differ in design, dimensions and application. Check fitment against the exact vehicle version, not just make and model.

How to select a mass air flow sensor

Compare OE number, sensor technology, housing, connector and engine version with the manufacturer's catalogue and vehicle documentation.

What may indicate a fault?

Rough running, loss of power and engine control fault codes call for diagnosis, but can have other causes. Inspect related parts before replacing the sensor.

Installation advice

Follow service instructions and any specified checks or adjustments. See engine sensors and controls and compare part numbers.
