WHEEL SPEED SENSOR
SKU: WSS-1021
WSS-1021 PAT Wheel Speed Sensor LHR
Wheel speed sensors, originally introduced for Anti-Lock Braking Systems (ABS), are now integral to numerous modern vehicle systems. With a focus on safety and customer demand, these sensors have become essential for the operation of intelligent safety systems and other vital vehicle functions.
- Supports multiple systems such as ABS, TCS, ESC, ADAS, and ACC
- Crucial for engine management, transmission control, and navigation systems
- Significantly impacts vehicle dynamics, driving comfort, safety, emissions, and fuel consumption
- Available in two types: passive (inductive) and active
- Passive sensors are inductive analogue types that do not require an external power supply
- Active sensors are digital hall sensor types with integrated electronics, requiring a power supply from the ABS module
- Active sensors offer accurate wheel speed detection from stationary, crucial for traction control and hill descent control
- Smaller and lighter design with insensitivity to vibration and temperature fluctuations
- Less sensitivity to changes in air gap and reduced electromagnetic interference
- Ability to detect forward and reverse movement
- Symptoms of a faulty wheel speed sensor include multiple warning lights on the dashboard, wheels locking during braking, pulsation of the brake pedal, erratic or no speedometer operation, and other seemingly unrelated system failures
- For effective diagnosis, use a suitable diagnostic tool to read fault codes, inspect the wiring and mechanical assemblies, check the output signal, supply voltage, and sensor resistance
Note: 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: 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.
