GeoBrakes stocks OEM-grade vehicle speed sensors confirmed to fit the Mazda 626, the components that supply vehicle speed data to the 626 transmission control module, ABS system, speedometer, and cruise control simultaneously. Every Mazda 626 sensor is direct-fit, calibrated to the correct signal frequency
The vehicle speed sensor on the Mazda 626 is a single component whose data feeds multiple vehicle systems at once on your 626. When it fails on the Mazda 626, the effects appear across your 626 speedometer, transmission, cruise control, and ABS simultaneously, making diagnosis less straightforward than a fault that affects only one system on the Mazda 626.
On older Mazda 626 vehicles and most rear-wheel-drive designs, a dedicated transmission-mounted speed sensor monitors output shaft speed on the 626 and serves as the primary reference for the 626 speedometer and transmission control module. On modern Mazda 626 front-wheel-drive and all-wheel-drive platforms, wheel hub sensors serve the dual function of ABS speed sensing and vehicle speed data delivery on the 626, one sensor feeding multiple Mazda 626 systems from a single mounting point.
Signal accuracy is the defining specification for a Mazda 626 vehicle speed sensor. A sensor that generates the wrong pulse frequency for your 626 control modules produces incorrect speedometer readings, mis-timed transmission shifts, and inaccurate ABS calibration on your Mazda 626, even if it passes a basic resistance test. Every speed sensor in the GeoBrakes catalogue is sourced to the correct signal frequency for the Mazda 626 exact year, make, model, and sensor position.
Can a faulty speed sensor affect the transmission on my Mazda 626?
Yes. The Mazda 626 transmission control module relies on vehicle speed data to calculate correct shift timing. A failed 626 speed sensor can cause erratic shifting, delayed upshifts, incorrect downshifts, or trigger 626 limp mode.
Will a bad vehicle speed sensor turn on the check engine light on my Mazda 626?
Yes. A failed Mazda 626 vehicle speed sensor typically stores fault codes P0500, P0501, or P0502. Depending on the 626, it may also trigger ABS, traction control, or transmission warning lights simultaneously.
Is the vehicle speed sensor the same as the ABS wheel speed sensor on my Mazda 626?
On many modern Mazda 626 vehicles, yes, wheel hub sensors serve both the ABS system and vehicle speed sensing simultaneously on your 626. On older 626 vehicles with transmission-mounted speed sensors, they are separate components. Use the GeoBrakes vehicle selector to confirm the correct sensor type for your Mazda 626.
