PAT Air Mass Meter: Your Reliable Mass Air Flow Sensor
Ensuring the smooth operation of your vehicle's engine management system, the PAT Air Mass Meter is a crucial component. Positioned between your air filter and throttle body, this Mass Air Flow Sensor measures incoming air and often incorporates the Intake Air Temperature Sensor (ATS). The data it collects is vital for your engine's ECU to accurately determine the fuel mix, ignition timing, and sometimes even transmission shifting.
- Functionality: The Mass Air Flow Sensor houses a small, electrically heated wire. Another sensor nearby monitors the wire's temperature. The amount of electricity needed to maintain the wire's heat directly represents airflow volume, providing your ECU with the information it needs for precise fuel injection.
- Potential Issues: A faulty Mass Air Flow Sensor can lead to a range of issues including rough idle, sluggish performance, black exhaust smoke, poor fuel economy, and even a warning light on your dashboard. The main issue is usually contamination of the hot wire by dust, dirt, or oil gunk, which prevents accurate airflow readings.
- Diagnosis: To identify any issues, check the sensor's signal with the appropriate scan tool or oscilloscope and compare it to your vehicle's specifications. Warning codes on your dashboard can also indicate a problem. Additionally, intake leaks or faulty wiring can affect the Mass Air Flow Sensor.
- PAT Emission: PAT Emission offers over 340 high-quality Air Flow Meters and sensors, suitable for a wide range of vehicles across Australia and New Zealand. Choosing PAT means choosing parts built to your car manufacturer's standards, ensuring the perfect fit and function.

Packaging note: PAT products may be supplied in PAT Premium packaging instead of the manufacturer's original box.
PAT sources EFI and engine-management parts from established OE-type manufacturers and repackages some of them in Australia. The manufacturer inside can change between batches as supply changes — for example, a part once made by Hitachi may now come from Bosch. Every unit is an OE-type part from a recognised manufacturer.
Packaging: Manufacturers periodically update their packaging and labelling. You may receive the current or a previous design — the product, formulation and part number are unchanged.
Fitment (vehicle-specific products): Vehicle fitment is based on manufacturer and supplier catalogue data and is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant, and parts on older vehicles may have been replaced with non-original or different-style components.
Before you buy, compare the product images with the part currently fitted to your vehicle — check shape, size, connectors and mounting points. If the part on your vehicle looks different, please contact us before purchasing. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing.
Not sure? Message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm fitment before you buy.
Parts returned because they do not suit the vehicle, where the listing matches the manufacturer's catalogue, are treated as a change of mind and must be unused, uninstalled and in original packaging. Nothing in this notice affects your rights under the Australian Consumer Law.
