A Mechanic's Guide to the 1991-1993 Dodge Stealth Vehicle Speed Sensor
Solve your erratic speedometer and shifting problems by understanding how to choose the right speed sensor.
- A faulty VSS is the primary cause of an erratic speedometer and poor automatic shifting on a 1991-1993 Stealth.
- Aftermarket brands like Standard Ignition and its True Tech line are reliable and cost-effective replacements.
- This is a good DIY project for a weekend mechanic; the main challenge is accessing the sensor by removing the battery tray.
- There are no known recalls for this specific part, so repair costs will not be covered by the manufacturer.
Is Your Dodge Stealth Speedometer Acting Up?
If you're dealing with a speedometer that jumps around, doesn't work at all, or if your automatic transmission is shifting hard and at the wrong times, a failing vehicle speed sensor (VSS) is a likely culprit. On the 1991-1993 Dodge Stealth, this sensor is a common wear item. Luckily, replacing it is straightforward and affordable with quality aftermarket parts.
Symptoms of a Bad Vehicle Speed Sensor
A bad VSS will give you some very clear signs. Here’s what to look for:
- Erratic or Dead Speedometer: The needle may bounce around unpredictably or just sit at zero, even when you're moving.
- Harsh Automatic Shifting: The transmission relies on the VSS to know when to shift. A bad signal can cause delayed, hard, or jerky shifts.
- Cruise Control Failure: If the car's computer doesn't know how fast you're going, it can't maintain your speed, so the cruise control won't engage.
- Check Engine Light: A failed VSS can trigger a Check Engine Light. You might see codes like P0500 if you scan the computer.
Don't Confuse VSS with Wheel Speed Sensors
Your Stealth also has wheel speed sensors for the Anti-lock Brake System (ABS). These are different parts located at each wheel. A bad wheel speed sensor will typically trigger an ABS light, not the transmission and speedometer issues caused by the main VSS.
Choosing the Right Aftermarket VSS
For a car like the 1991-1993 Stealth, finding a new OEM (Original Equipment Manufacturer) speed sensor from Dodge is nearly impossible. Aftermarket parts are your best bet. They are widely available, affordable, and work well. The key is to choose a brand with a good reputation.
Here’s a look at the brands available:
- Standard Ignition (SC Series): Standard Motor Products (SMP) has been making quality parts for a very long time. Their main line of sensors is known for reliable performance and proper fit, making them a solid choice that many professional mechanics trust.
- True Tech (T-Series): True Tech is a product line from Standard Ignition. It is designed to offer dependable, OE-grade components at a more budget-friendly price point. This is a great option if you're looking for a reliable repair without the higher cost.
Pro Tip: Both Standard Ignition and True Tech are good choices. Standard is often seen as the premium aftermarket option, while True Tech provides excellent value. For a vehicle of this age, either will serve you well. The most important thing is a new, functioning sensor.
