Chrysler Intrepid (1993-2004) Automatic Transmission Output Speed Sensor Guide
Experiencing a dead speedometer or getting stuck in gear? A faulty output speed sensor is a very common and fixable issue on your Intrepid.
- A bad output speed sensor is a very common cause of limp mode and a dead speedometer on the 1993-2004 Intrepid.
- It is highly recommended to replace both the input and output speed sensors at the same time to prevent future issues.
- This is an easy and inexpensive DIY repair that most owners can do in under an hour with basic tools.
- Reputable aftermarket brands like NGK (NTK) and Standard Ignition (SMP) offer reliable, cost-effective alternatives to OEM parts.
Is a Bad Output Speed Sensor Causing Your Intrepid's Problems?
If your Chrysler Intrepid suddenly starts shifting hard, the speedometer drops to zero while driving, or the transmission gets stuck in second gear, a bad output speed sensor is the most likely cause. This is a very common failure point on these cars due to age and constant exposure to heat from the transmission. When the sensor fails, the transmission's computer gets confused and triggers a protective mode called "limp mode" to prevent damage. This locks the transmission in a single gear (usually second), allowing you to drive slowly to a safe location.
Input vs. Output Sensors
Your Intrepid uses both an input and an output speed sensor. The output sensor controls the speedometer, while the input sensor measures the speed of the transmission's input shaft. While they can be bought and replaced separately, it is highly recommended by mechanics and experienced owners to replace them as a pair. If one has failed from age, the other is likely not far behind. Replacing both at the same time saves you from doing the same job twice.
Choosing the Right Aftermarket Sensor
You don't need to buy an expensive OEM Mopar part for this repair. Several aftermarket brands offer reliable replacements that meet or exceed factory quality. Given the low cost of the part, it's wise to choose a reputable brand to avoid premature failure.
- Premium Aftermarket (OEM Quality): Brands like NGK (NTK) and Standard Ignition (SMP) have a strong reputation for producing high-quality electronic sensors that are built to last. They are trusted choices for both DIYers and professional shops.
- Standard Replacement: Brands such as ATP are well-known in the transmission parts industry and offer a good balance of quality and value.
- Budget-Friendly: Brands like Pioneer Cable, Skyward, and True Tech are typically more affordable. While they can be a good option for a budget-conscious repair, long-term reliability may be less certain compared to premium brands.
Cost of Replacing the Output Speed Sensor
| Part/Service | Typical Cost |
|---|---|
| New Aftermarket Sensor | $13.98 - $38.64 |
| Shop Labor | $75 - $150 |
| Total Professional Repair | $90 - $190 |
DIY Savings
This is a very DIY-friendly job. The output speed sensor is located on the outside of the transmission on the driver's side and is held in by a single bolt or simply threaded into place. With basic hand tools like a 1-inch socket and a ratchet, most owners can replace it in under an hour, saving significantly on labor costs.
Frequently Asked Questions (FAQ)
Where is the output speed sensor located on a 1993-2004 Intrepid?
The output speed sensor is on the driver's side of the transmission, toward the rear of the vehicle, often near the exhaust pipe. The input sensor is located nearby, but closer to the front of the car. You will need to safely get under the vehicle to access them.
What is "limp mode"?
Limp mode is a safety feature that activates when the transmission computer detects a serious problem, like a failed speed sensor. It locks the transmission into a single gear (usually 2nd) to prevent further damage and allow you to drive slowly to a repair shop. You will have very slow acceleration and won't be able to reach highway speeds. Restarting the car can sometimes temporarily reset it.
Are there any recalls for the Intrepid's speed sensors?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no specific recalls for the transmission speed sensors on the 1993-2004 Chrysler Intrepid. Failures are considered normal wear and tear for a vehicle of this age.
Do I need to reset the computer after replacing the sensor?
While a professional scan tool can clear the codes, a simple way to reset the system is to disconnect the battery for about 10-15 minutes after the new sensor is installed. This will clear the fault codes from the transmission computer's memory.
