PAT Front Left Wheel Speed Sensor — WSS-337
The PAT WSS-337 is an ABS wheel speed sensor for the front left (FL) position, supplied individually. Wheel speed sensors were introduced for Anti-Lock Braking Systems (ABS) and are now used by many other vehicle safety and driveline systems.
- Accurate wheel speed detection from stationary, which traction control and hill descent control rely on
- Smaller and lighter design
- Insensitive to vibration and temperature fluctuations
- Less sensitive to changes in air gap
- Reduced electromagnetic interference
- Detects forward and reverse movement
- Backed by a 12 month warranty
Symptoms of a faulty wheel speed sensor:
- Multiple warning lights displayed on the dashboard
- Wheels locking during braking
- Pulsation of the brake pedal
- Erratic or no speedometer operation
- Other seemingly unrelated system failures
Troubleshooting and diagnostics:
- Use a suitable diagnostic tool to read fault codes
- Inspect the wiring for damage or breaks
- Inspect the mechanical assemblies for issues
- Check the output signal using a scope or suitable diagnostic tool
- Check the supply voltage for active sensors
- Check the sensor resistance for inductive sensors
* For correct fitment ensure the vehicle is listed in the compatibility list AND read any notes associated with the product. If there are no vehicle details listed, please send a message.
Packaging note: This item 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.
