GeoBrakes stocks OEM-grade vehicle speed sensors confirmed to fit the Gmc K3500, the components that supply vehicle speed data to the K3500 transmission control module, ABS system, speedometer, and cruise control simultaneously. Every Gmc K3500 sensor is direct-fit, calibrated to the correct signal frequency
The vehicle speed sensor on the Gmc K3500 is a single component whose data feeds multiple vehicle systems at once on your K3500. When it fails on the Gmc K3500, the effects appear across your K3500 speedometer, transmission, cruise control, and ABS simultaneously, making diagnosis less straightforward than a fault that affects only one system on the Gmc K3500.
On older Gmc K3500 vehicles and most rear-wheel-drive designs, a dedicated transmission-mounted speed sensor monitors output shaft speed on the K3500 and serves as the primary reference for the K3500 speedometer and transmission control module. On modern Gmc K3500 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 K3500, one sensor feeding multiple Gmc K3500 systems from a single mounting point.
Signal accuracy is the defining specification for a Gmc K3500 vehicle speed sensor. A sensor that generates the wrong pulse frequency for your K3500 control modules produces incorrect speedometer readings, mis-timed transmission shifts, and inaccurate ABS calibration on your Gmc K3500, even if it passes a basic resistance test. Every speed sensor in the GeoBrakes catalogue is sourced to the correct signal frequency for the Gmc K3500 exact year, make, model, and sensor position.
Can a faulty speed sensor affect the transmission on my Gmc K3500?
Yes. The Gmc K3500 transmission control module relies on vehicle speed data to calculate correct shift timing. A failed K3500 speed sensor can cause erratic shifting, delayed upshifts, incorrect downshifts, or trigger K3500 limp mode.
Will a bad vehicle speed sensor turn on the check engine light on my Gmc K3500?
Yes. A failed Gmc K3500 vehicle speed sensor typically stores fault codes P0500, P0501, or P0502. Depending on the K3500, 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 Gmc K3500?
On many modern Gmc K3500 vehicles, yes, wheel hub sensors serve both the ABS system and vehicle speed sensing simultaneously on your K3500. On older K3500 vehicles with transmission-mounted speed sensors, they are separate components. Use the GeoBrakes vehicle selector to confirm the correct sensor type for your Gmc K3500.
