Guide to the 1990-1998 Eagle Talon Automatic Transmission Output Speed Sensor
Solve your Talon's erratic shifting and dead speedometer by understanding this critical sensor.
- A bouncing speedometer and harsh automatic shifting are the most common symptoms of a bad output speed sensor on a Talon.
- Always inspect the sensor's wiring and connector for damage before buying a new part.
- A quality aftermarket brand like Standard Ignition is a reliable choice, while brands like ATP and Pioneer offer a functional, budget-friendly alternative.
- Replacing the sensor is a DIY-friendly job that can prevent more serious transmission damage.
Understanding the Speed Sensor in Your 1990-1998 Talon
If you're dealing with a speedometer that's acting up or your automatic transmission is shifting hard, a bad output speed sensor is a likely culprit. On the 1990-1998 Eagle Talon, also known as a DSM (Diamond-Star Motors) car, this part is a common failure item due to age. The sensor's job is simple but vital: it tells the car's computers how fast you're going. This signal is used for everything from the speedometer on your dash to the shift points in your automatic transmission. When it fails, it can cause a variety of noticeable and annoying problems.
Don't Ignore Shifting Problems
Driving with a bad speed sensor can cause the transmission to shift harshly. Over time, this can cause excess wear and tear on internal transmission components, leading to more expensive repairs down the road. It's best to address this issue as soon as symptoms appear.
Choosing the Right Aftermarket Sensor
For a vehicle this age, finding a new OEM sensor from Mitsubishi is difficult and often unnecessary. Quality aftermarket parts provide a reliable and cost-effective solution. Aftermarket brands generally fall into a few tiers:
- Premium Brands (Standard Ignition): Standard Motor Products (SMP), sold under the Standard Ignition brand, is a well-regarded manufacturer in the aftermarket community. They are known for producing parts that meet or exceed OE specifications and undergo extensive testing. This is often the top choice for reliability.
- Value Brands (ATP, Pioneer Cable): Brands like ATP and Pioneer offer a more budget-friendly option. They are designed to be direct-fit replacements and can be a good choice for a daily driver or if cost is a major concern. While they may not have the same long-standing reputation as premium brands, they offer a functional replacement.
- Economy/Store Brands (Skyward, True Tech): These often represent the most affordable tier. Quality can be variable, but they meet the basic need for a functional sensor at the lowest price point.
Check the Connector First!
Before you order a new part, take a minute to find the sensor on your transmission and inspect the wiring connector. After decades of heat and vibration, these plastic connectors can become brittle, and the wires can get corroded or frayed. Sometimes, just cleaning the contacts and ensuring a tight connection can fix the problem for free.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $13.98 - $38.64 |
| Shop Labor | $90 - $150 |
| New OEM | Discontinued / Hard to Find |
| Used OEM | $25 - $60 |
Frequently Asked Questions (FAQ)
Where is the output speed sensor located on my Talon?
On automatic transmission DSMs, the output speed sensor is typically located on the top of the transmission housing, often under the battery tray or near the throttle body area. It will have a 2 or 3-wire electrical connector plugged into it.
Is this a difficult part to replace myself?
For a DIY mechanic, this is a very feasible job. It usually takes less than an hour and requires basic hand tools. The main challenge is accessing the sensor, which may be in a tight space. You will likely need to remove the battery and battery tray to get clear access.
Will a bad speed sensor cause a Check Engine Light?
Yes, especially on 1995-1998 (2G) models. A failing output speed sensor will often trigger a Check Engine Light with a diagnostic trouble code like P0720 (Output Speed Sensor Circuit Malfunction) or P0500 (Vehicle Speed Sensor Malfunction).
Are there any recalls for this issue?
No recalls were found specifically for the transmission speed sensor. There was a recall (NHTSA ID: 98V069002) for the transfer case on AWD models from 1990-1998 due to potential oil leaks, but this is unrelated to the electronic speed sensor itself.
Technical Specifications
The sensor is typically a 2 or 3-pin magnetic sensor that mounts to the automatic transaxle housing. It generates a signal based on the rotation of an internal gear. Note that sensors for 1G (1990-1994) and 2G (1995-1998) models may differ and are not interchangeable.
