GeoBrakes stocks OEM-grade vehicle speed sensors confirmed to fit the Gmc G1500, the components that supply vehicle speed data to the G1500 transmission control module, ABS system, speedometer, and cruise control simultaneously. Every Gmc G1500 sensor is direct-fit, calibrated to the correct signal frequency
The vehicle speed sensor on the Gmc G1500 is a single component whose data feeds multiple vehicle systems at once on your G1500. When it fails on the Gmc G1500, the effects appear across your G1500 speedometer, transmission, cruise control, and ABS simultaneously, making diagnosis less straightforward than a fault that affects only one system on the Gmc G1500.
On older Gmc G1500 vehicles and most rear-wheel-drive designs, a dedicated transmission-mounted speed sensor monitors output shaft speed on the G1500 and serves as the primary reference for the G1500 speedometer and transmission control module. On modern Gmc G1500 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 G1500, one sensor feeding multiple Gmc G1500 systems from a single mounting point.
Signal accuracy is the defining specification for a Gmc G1500 vehicle speed sensor. A sensor that generates the wrong pulse frequency for your G1500 control modules produces incorrect speedometer readings, mis-timed transmission shifts, and inaccurate ABS calibration on your Gmc G1500, 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 G1500 exact year, make, model, and sensor position.
Can a faulty speed sensor affect the transmission on my Gmc G1500?
Yes. The Gmc G1500 transmission control module relies on vehicle speed data to calculate correct shift timing. A failed G1500 speed sensor can cause erratic shifting, delayed upshifts, incorrect downshifts, or trigger G1500 limp mode.
Will a bad vehicle speed sensor turn on the check engine light on my Gmc G1500?
Yes. A failed Gmc G1500 vehicle speed sensor typically stores fault codes P0500, P0501, or P0502. Depending on the G1500, 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 G1500?
On many modern Gmc G1500 vehicles, yes, wheel hub sensors serve both the ABS system and vehicle speed sensing simultaneously on your G1500. On older G1500 vehicles with transmission-mounted speed sensors, they are separate components. Use the GeoBrakes vehicle selector to confirm the correct sensor type for your Gmc G1500.
