Shop replacement vehicle sensors, relays and electronic control units used across modern automotive systems. Electronic components monitor operating conditions, control functions and communicate information between different vehicle systems.

Depending on the vehicle, components can include engine sensors, ABS sensors, temperature sensors, pressure sensors, oxygen sensors, relays, electronic control modules and other control units.

A diagnostic fault code does not always mean that the named sensor or control unit has failed. Wiring, connectors, power supply, communication faults and other components can produce similar symptoms. Proper diagnosis is therefore important before replacing electronic parts.

When ordering sensors or control units, exact fitment is essential. Use the vehicle VIN, registration number, make, model, engine and year. For electronic modules, the original part number and software or hardware version may also be important.

Some control units may require coding, programming or configuration after installation. Check the product information and vehicle requirements before ordering.
