Is Your Speedometer Acting Up? Signs of a Failing Vehicle Speed Sensor
A bad vehicle speed sensor on a Workhorse FasTrack chassis, which often uses a GM 4L80-E transmission, will cause several distinct problems. Because the sensor's signal is essential for both the speedometer and transmission function, you will likely notice issues with both. The symptoms often start intermittently before the sensor fails completely.
Common Failure Symptoms:
- Erratic or Dead Speedometer: The speedometer may jump around wildly, read an incorrect speed, or drop to zero while driving.
- Improper Transmission Shifting: Your transmission may shift harshly, at the wrong times, or refuse to shift out of a low gear.
- Cruise Control Not Working: The cruise control system relies on a steady speed signal from the VSS, so it will not engage if the sensor is faulty.
- Check Engine Light: A failing VSS will almost always trigger a Check Engine Light and store a diagnostic trouble code like P0500 or P0502.
Choosing the Right Aftermarket Speed Sensor
For the 2002-2005 FasTrack FT1061, the aftermarket is the most common source for a new Vehicle Speed Sensor. While an OEM part may exist, it can be difficult to source and more expensive. Aftermarket brands offer a reliable and affordable alternative.
Brand Tiers for Your Workhorse:
- Premium Aftermarket (Standard Ignition): Standard Motor Products (SMP), the company behind the Standard Ignition brand, has a long-standing reputation for producing quality electronic parts that meet or exceed OEM standards. For a critical sensor that affects drivability, choosing a premium brand like Standard is a solid investment in reliability.
- Standard Aftermarket (Dorman): Dorman is another widely available brand that produces a compatible sensor for this vehicle. These parts provide a functional replacement at a budget-friendly price point.
Pro Tip: The VSS for this chassis is often shared with many GM trucks and vans from the same era that use the 4L80-E automatic transmission. Verifying the part based on the transmission model can help ensure you get the correct sensor.
