PAT Wheel Speed Sensor WSS-364
The PAT Wheel Speed Sensor WSS-364 is designed for the front of the vehicle and plays a crucial role in various modern vehicle systems beyond just ABS. - Essential for intelligent safety systems and other vital vehicle functions - Utilises advanced data transmission systems like the Controller Area Network (CAN) - Influences systems such as ABS, TCS, ESC, ADAS, and ACC - Supports engine management, transmission control, and navigation systems - Impacts vehicle dynamics, driving comfort, safety, emissions, and fuel consumption **Types of Wheel Speed Sensors:** **Passive/Inductive Wheel Speed Sensors:** - Inductive analogue type, no external power supply needed - Consists of a wire coil wound around a soft iron core, connected to a permanent magnet - Detects wheel rotation through changes in the magnetic field - Can become inaccurate at low speeds and sensitive to positioning and damage **Active Wheel Speed Sensors:** - Digital hall sensor type with integrated electronics, requires power supply from ABS module - Two types: magneto-resistive and hall sensors - Generates a digital signal, can have 2 or 3 terminals - Triggered by opposing magnets around a multipole ring (encoder) or a toothed ring - Encoders can be located inside the wheel bearing, on the wheel bearing, or on the wheel carrier **Advantages of Active Sensors:** - Accurate wheel speed detection from stationary - Smaller and lighter design - Insensitivity to vibration and temperature fluctuations - Less sensitivity to changes in air gap - Reduced electromagnetic interference - Ability to detect forward and reverse movement **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 **Note:** - For correct fitment, ensure the vehicle is listed in the compatibility list and read any notes associated with the product.

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.
