GeoBrakes stocks OEM-grade vehicle speed sensors confirmed to fit the Chevrolet R20 Suburban, the components that supply vehicle speed data to the R20 Suburban transmission control module, ABS system, speedometer, and cruise control simultaneously. Every Chevrolet R20 Suburban sensor is direct-fit, calibrated to the correct signal frequency
The vehicle speed sensor on the Chevrolet R20 Suburban is a single component whose data feeds multiple vehicle systems at once on your R20 Suburban. When it fails on the Chevrolet R20 Suburban, the effects appear across your R20 Suburban speedometer, transmission, cruise control, and ABS simultaneously, making diagnosis less straightforward than a fault that affects only one system on the Chevrolet R20 Suburban.
On older Chevrolet R20 Suburban vehicles and most rear-wheel-drive designs, a dedicated transmission-mounted speed sensor monitors output shaft speed on the R20 Suburban and serves as the primary reference for the R20 Suburban speedometer and transmission control module. On modern Chevrolet R20 Suburban 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 R20 Suburban, one sensor feeding multiple Chevrolet R20 Suburban systems from a single mounting point.
Signal accuracy is the defining specification for a Chevrolet R20 Suburban vehicle speed sensor. A sensor that generates the wrong pulse frequency for your R20 Suburban control modules produces incorrect speedometer readings, mis-timed transmission shifts, and inaccurate ABS calibration on your Chevrolet R20 Suburban, even if it passes a basic resistance test. Every speed sensor in the GeoBrakes catalogue is sourced to the correct signal frequency for the Chevrolet R20 Suburban exact year, make, model, and sensor position.
Can a faulty speed sensor affect the transmission on my Chevrolet R20 Suburban?
Yes. The Chevrolet R20 Suburban transmission control module relies on vehicle speed data to calculate correct shift timing. A failed R20 Suburban speed sensor can cause erratic shifting, delayed upshifts, incorrect downshifts, or trigger R20 Suburban limp mode.
Will a bad vehicle speed sensor turn on the check engine light on my Chevrolet R20 Suburban?
Yes. A failed Chevrolet R20 Suburban vehicle speed sensor typically stores fault codes P0500, P0501, or P0502. Depending on the R20 Suburban, 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 Chevrolet R20 Suburban?
On many modern Chevrolet R20 Suburban vehicles, yes, wheel hub sensors serve both the ABS system and vehicle speed sensing simultaneously on your R20 Suburban. On older R20 Suburban vehicles with transmission-mounted speed sensors, they are separate components.
