Starting at $51.95, AutoBuffy stocks 3 vehicle speed sensors from Dorman, Standard Ignition, and GPD that fit the Dodge B1500. The vehicle speed sensor (VSS) measures how fast your wheels or transmission output shaft are turning and feeds that data to the ECU, ABS module, and speedometer. A failing sensor triggers erratic speedometer readings, transmission shift problems, and ABS faults that won't clear.
The Dodge B1500 may use one or more speed sensors depending on whether it has an ABS system, all-wheel drive, or an electronically controlled automatic transmission. Before ordering, identify whether you need the transmission output shaft sensor, a wheel-mounted ABS/VSS sensor, or both — they are different parts with different connectors. OE-equivalent sensors are the safest choice for vehicles where the VSS also feeds the ABS and transmission control modules.
| Option | Best for | What you get |
|---|---|---|
| OE-Equivalent (direct-fit) | Daily drivers and vehicles where VSS feeds ABS, TCM, or cruise control | Plug-and-play fitment, matched magnet ring teeth count, and reliable signal accuracy out of the box |
| OEM (dealer-sourced) | High-mileage vehicles already on second or third sensor, or when prior aftermarket parts failed quickly | Exact original specification, factory warranty support, highest cost |
| Transmission Output Shaft Sensor | Vehicles with electronically shifted automatics showing shift quality codes alongside P0500 series codes | Dedicated sensor reading transmission tail-shaft speed rather than a wheel hub; resolves shift-specific faults |
| Wheel Speed Sensor (ABS/VSS combined) | Vehicles where a single reluctor-ring sensor at each hub handles both ABS and speedometer input | Integrated bearing or ring design specific to hub position; must match axle side (front left, front right, rear) |
A transmission output shaft VSS is typically a single-bolt sensor that unplugs and threads straight out from the transmission housing — the main challenge is access and breaking a corroded sensor free. Wheel-mounted ABS/VSS sensors bolt to the steering knuckle or hub and require safely raising the vehicle; on driven axles the axle nut may need to be removed first. Always clear codes and verify the fault is resolved with a test drive before considering the job complete.
