Is Your Dodge Shadow Hesitating or Stalling? It Could Be the TPS.
If your 1987-1994 Dodge Shadow is experiencing engine problems like stalling, poor acceleration, or erratic shifting, a failing Throttle Position Sensor (TPS) is a likely suspect. This sensor tells your engine's computer how much power you're asking for. When it fails, the computer gets bad information, leading to a host of drivability issues. Because these cars use older technology, the symptoms are often very noticeable.
Common Symptoms of a Bad TPS in a Dodge Shadow
- Hesitation or Stumbling: The engine may hesitate or stumble when you press the gas pedal.
- Stalling: The engine might stall unexpectedly, especially when idling or coming to a stop.
- Poor or No Acceleration: The car feels sluggish and lacks power, no matter how hard you press the gas.
- Incorrect Shifting (Automatic Transmission): The transmission may shift at the wrong times, or have trouble shifting gears at all.
- Unstable Idle: The engine idle may be rough, or it might surge up and down for no reason.
- Check Engine Light: A failing TPS can trigger the Check Engine Light.
Choosing the Right Aftermarket TPS
For a vehicle like the 1987-1994 Dodge Shadow, original Mopar parts are becoming scarce and expensive. The good news is that many quality aftermarket brands are available. Since the TPS is a critical sensor, it's wise to avoid the cheapest, no-name options, which can fail quickly.
Here’s a breakdown of the brands available in our inventory:
- Premium Aftermarket (Recommended): Brands like Delphi, NGK, and Standard Ignition (SMP) have a strong reputation for producing reliable sensors that meet or exceed original specifications. They use better materials and have stricter quality control, making them a solid choice for long-term reliability.
- Standard Aftermarket: Brands like Walker Products and Motorad offer a good balance of price and quality. They are a dependable option for daily drivers and are generally considered a step up from budget parts.
- Budget-Friendly: Brands like True Tech, Global Parts, and Replacement offer a low-cost alternative. While functional, they may not have the same durability or precise calibration as premium brands. They can be a solution for a tight budget, but be aware they may not last as long.
Pro Tip: Installation is a DIY Job
Replacing the TPS on a Dodge Shadow is one of the easiest repairs you can do. It is located on the side of the throttle body, held on by two T25 Torx screws, and has a simple electrical connector. Most owners with basic hand tools can complete this job in under 15 minutes. There is no complex calibration required for this vehicle; simply bolt on the new part, plug it in, and you're done. Some mechanics recommend disconnecting the battery for a few minutes to reset the computer after replacement.

Do I need to adjust or calibrate the new TPS?
