AIR FLOW METER
SKU: AFM-319
PAT Air Flow Meter: The Essential Engine Management Component
Positioned between the air filter and throttle body, the PAT Air Flow Meter plays a pivotal role in your engine management system. This device measures the incoming air and often incorporates the Intake Air Temperature Sensor (ATS). The data collected by this sensor assists your engine's ECU in determining the correct fuel mix, ignition timing, and occasionally, transmission shifting.
Key Features:
- Contains a tiny, electrically heated wire that measures airflow volume
- Includes an additional sensor to monitor the wire's temperature
- Helps your ECU to precisely inject the right amount of fuel
- Can detect and indicate potential issues through warning codes on your dash
Potential Issues:
A faulty PAT Air Flow Meter can lead to a range of issues such as rough idle, sluggish performance, black exhaust smoke, poor fuel economy, and even trigger a warning light on your dash. The primary cause of these problems is contamination of the hot wire by dust, dirt, or oil gunk, which can prevent accurate airflow readings. While newer models are designed to minimise this issue, they are not completely immune. Oily aftermarket air filters are a common source of contamination.
Diagnosing the Issue:
Use the appropriate scan tool or oscilloscope to check the sensor's signal and compare it to the specifications for your vehicle. Warning codes on your dash can also indicate a problem (look out for codes starting with P0068, P0100, P0101, P0102, P0103, P0104). Basic issues such as intake leaks or faulty wiring can also affect the PAT Air Flow Meter.

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.
