Chrysler Sebring Vehicle Speed Sensor Guide: 1995-2000
Solve common speedometer, shifting, and cruise control problems by understanding this critical sensor.
- A bad VSS is a common cause of erratic speedometer readings and harsh shifting on the 1995-2000 Sebring.
- The output speed sensor is the one that controls the speedometer; it's located on the transmission and is accessible after removing the airbox.
- Before replacing the sensor, rule out issues with the alternator, as electrical interference can cause identical symptoms.
- Replacement is a simple DIY task for most, requiring basic tools and about an hour of time.
Is Your Sebring's Speedometer Acting Up?
A failing vehicle speed sensor (VSS) is a common issue on the first-generation Chrysler Sebring that can cause a host of confusing problems. Because this one sensor provides speed data to multiple systems, its failure can mimic more serious transmission issues. Understanding the symptoms can save you from an incorrect diagnosis.
Top 5 Symptoms of a Bad Vehicle Speed Sensor
- Erratic or Dead Speedometer: The most obvious sign is a speedometer that jumps around, reads incorrectly, or doesn't move at all. 🎬 Watch a demonstration of a Sebring speedometer acting up.
- Harsh or Incorrect Shifting: The automatic transmission may shift hard, late, or seem to hunt for the right gear because it doesn't know how fast the car is moving.
- Cruise Control Not Working: If the computer doesn't receive a reliable speed signal, it will not allow the cruise control to engage.
- Check Engine Light: A faulty VSS will often trigger the Check Engine Light and store a diagnostic trouble code, most commonly P0500. 🎬 See a breakdown of P0500 causes and how to fix it.
- Stalling or Hesitation: In some cases, a bad VSS signal can confuse the engine's computer during deceleration, leading to a rough idle or stalling when coming to a stop.
Input vs. Output Sensors
Your Sebring's automatic transmission has both an input and an output speed sensor. The output sensor is the one that measures the final speed sent to the wheels and controls the speedometer. While both can fail, the output sensor is the primary culprit for the symptoms listed above.
Choosing the Right Aftermarket VSS
Since the VSS is crucial for proper transmission function, choosing a quality replacement part is important. While an OEM Mopar part offers a guaranteed fit and function, several aftermarket brands provide reliable alternatives at a better price. Aftermarket parts can be grouped into tiers based on their reputation for quality and engineering.
- Premium Brands (Closer to OEM Quality): Brands like Delphi and Standard Ignition (SMP) have a strong reputation as original equipment suppliers for many automakers. They emphasize OE-level testing and calibration, making them a safe bet for reliability and longevity.
- Standard Quality Brands: Companies like Walker Products and Holstein produce a wide range of sensors that meet or exceed OE specifications and are often 100% factory tested. These offer a good balance of price and quality for most repairs.
- Economy Brands: Brands such as Crown Automotive, Skyward, True Tech, and URO Parts provide budget-friendly options. While they can get the job done, they may not have the same level of validation or long-term durability as premium brands.
Pro Tip: Check Your Alternator First!
A failing alternator can produce electrical interference or "noise" that disrupts the VSS signal, causing identical symptoms like a bouncing speedometer even when the car is stopped. If you also have a weak battery or a whining noise from the engine, have your charging system tested before replacing the speed sensor.
Typical Replacement Costs
The cost for a new aftermarket vehicle speed sensor is very reasonable. The biggest variable is whether you do the work yourself or have a shop perform the replacement.
| Part or Service | Estimated Cost |
|---|---|
| New OEM (Mopar) Sensor | $50 - $75 |
| New Aftermarket Sensor | $14 - $85 |
| Shop Labor | $60 - $120 |
Frequently Asked Questions
Can I replace the VSS myself?
Yes, this is a DIY-friendly job for most home mechanics. The output speed sensor is located on the outside of the transmission. Access usually requires removing the air filter box. 🎬 Watch this step-by-step guide on replacing the speed sensor. The sensor itself is held in by a single bolt or simply screws into the transmission case and can be removed with a 1-inch socket or wrench.
Is it safe to drive with a bad speed sensor?
It is not recommended. While the car may be drivable, you will not have a working speedometer, and the transmission may shift unpredictably, which can be a safety hazard. It's best to get it repaired as soon as possible to avoid unsafe driving conditions and potential damage to the transmission.
What does the P0500 code mean?
P0500 is the standard diagnostic trouble code for "Vehicle Speed Sensor Malfunction." It means the engine control module (ECM) is not receiving a proper signal, or the signal is erratic. While this usually points to a bad sensor, it can also be caused by wiring issues or, as mentioned, interference from a bad alternator.
Are there any recalls for this part?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any safety recalls specifically for the vehicle speed sensor on the 1995-2000 Chrysler Sebring.
