Dodge Stratus Automatic Transmission Output Speed Sensor (1995-2006)
Fix your 1995-2006 Dodge Stratus's limp mode, erratic shifting, and speedometer issues by replacing a faulty output speed sensor.
- A faulty output speed sensor is the most common cause of limp mode and an erratic speedometer on a 1995-2006 Stratus.
- The Check Engine Light with code P0720 specifically points to this sensor.
- This is a DIY-friendly repair that can be done in about an hour with basic tools.
- It is highly recommended to replace both the input and output speed sensors at the same time for reliability.
Is Your Stratus Stuck in Gear or Shifting Hard?
A common problem on the 1995-2006 Dodge Stratus is the failure of the transmission speed sensors. These cars use an A604/41TE automatic transmission, which has both an Input Speed Sensor (ISS) and an Output Speed Sensor (OSS). When the output sensor fails, it can cause a Check Engine Light and very noticeable issues. The most common symptoms are the transmission getting stuck in second gear, known as "limp mode," harsh or slamming shifts, and a speedometer that bounces around or stops working completely.
Limp Mode is a Major Symptom
If your Stratus suddenly refuses to shift out of a low gear 🎬 Learn more about the causes and signs of limp mode., you are likely in "limp mode." This is a safety feature designed to protect the transmission from further damage when it loses a signal from a critical sensor, like the OSS. You will have limited speed and poor acceleration. This problem will not fix itself and requires replacing the faulty sensor.
Choosing the Right Aftermarket Sensor
For an older vehicle like the 1995-2006 Stratus, you don't need to pay high dealership prices for an OEM Mopar sensor. A quality aftermarket sensor offers excellent performance and value. However, not all aftermarket brands are created equal. Based on owner feedback and mechanic consensus, here is a breakdown of reliable choices:
- Top Tier (OEM Quality or Equivalent): Brands like NGK (NTK) and Standard Motor Products (SMP) have a strong reputation for producing reliable sensors that meet or exceed OEM specifications. Beck Arnley is also a great choice, as they often repackage the original factory parts.
- Reliable Value: Brands such as ATP and Pioneer Cable offer a cost-effective solution that is a significant step up from no-name online parts. They are a good balance of price and quality for a budget-conscious repair.
- Budget Brands: While brands like Skyward and True Tech are the most affordable, they may have a higher risk of early failure compared to more established brands. For a critical sensor that is relatively easy to replace, investing a few extra dollars in a better brand is often worth it to avoid doing the job twice.
Pro Tip: The Dodge Stratus has both an input and an output speed sensor. They are located near each other and often fail around the same time. Since the labor is the same, it is highly recommended to replace both sensors at the same time 🎬 Watch this step-by-step guide to installing both speed sensors. to prevent future issues.

Frequently Asked Questions
Where is the output speed sensor located on a Dodge Stratus?
The input and output speed sensors are located on the front side of the automatic transmission case. You can access them from the top of the engine bay, though they may be partially hidden by other components and wiring. They are each held in by a single bolt.
Can I replace the output speed sensor myself?
Yes, this is a good DIY job for a home mechanic. The most difficult part is usually reaching the sensor in the tight engine bay. You will need basic hand tools like a socket and ratchet. Be careful not to over-tighten the new sensor, as it is made of plastic.
Are there any recalls for the Stratus speed sensor?

My speedometer is dead, but the car shifts okay. Is it the output sensor?
Yes, most likely. An erratic or dead speedometer is the classic symptom of a failed *output* speed sensor 🎬 See other common signs of a bad vehicle speed sensor., as this sensor provides the signal for the speedometer. Shifting problems may appear later or be less noticeable at first.
What OBD-II code is for a bad output speed sensor?
The most common code for an output speed sensor circuit malfunction is P0720. You may also see a general transmission fault code, P0700, which often appears alongside more specific codes.
