A Guide to the Fuel Injection Throttle Body for the 2013-2019 Ford Taurus
Understanding the common and sudden throttle body failures in your Ford Taurus and how to choose the right replacement part.
- The original throttle body on 2013-2019 Taurus models has a very high failure rate, causing a dangerous 'limp mode'.
- Ford's extended warranty program (13N03) for this part has expired, so you will have to pay for the replacement.
- Replacement is a simple DIY job that takes about an hour with basic tools.
- After installation, a simple 'relearn' procedure is required and can be done without any special tools.
A Widespread and Sudden Problem
If you own a 2013-2019 Ford Taurus, you should be aware of a very common issue with the original electronic throttle body (ETB). Many owners have experienced a sudden and alarming loss of engine power while driving. The vehicle unexpectedly enters a reduced power state known as "limp home mode," making it unable to accelerate properly. This happens because the internal electronic contacts within the throttle body can become contaminated, leading to a poor electrical connection.
Ford's Customer Satisfaction Program 13N03
Ford acknowledged this issue by creating Customer Satisfaction Program 13N03, which extended the warranty on the throttle body to 10 years or 150,000 miles. However, this program has since expired for all eligible vehicles. This means that if your original throttle body fails now, the repair is no longer covered by this extended warranty.
Symptoms of a Failing Throttle Body
The signs of a bad throttle body on your Taurus are hard to miss. The most dramatic symptom is the sudden activation of "limp mode," but other signs can appear first. Look out for:
- Sudden Loss of Power: The vehicle abruptly loses the ability to accelerate, and a wrench icon appears on the dashboard. 🎬 Watch: How to diagnose and replace a Taurus throttle body.
- Check Engine Light: The Malfunction Indicator Lamp (MIL) or a wrench-shaped light will illuminate.
- Rough or Unstable Idle: The engine may idle too high or fluctuate unpredictably.
- Hesitation or Stalling: The car may hesitate when you press the gas pedal or stall completely, especially when coming to a stop.
- Error Codes: A code scanner will often show DTCs like P2111 (Stuck Open) or P2112 (Stuck Closed). 🎬 See what causes a P2112 code and how to fix it.
Choosing the Right Aftermarket Throttle Body
When replacing the throttle body, you have the choice between an original equipment (OEM) part from Ford and several aftermarket brands. For this specific part, a new aftermarket unit can be a reliable and cost-effective choice, as many are designed to fix the flaws of the original part.
- Premium Aftermarket (e.g., Hitachi): Hitachi is a known OEM supplier for many car brands and has a reputation for high-quality electronics. Choosing a brand like this often means you are getting a part that meets or exceeds the original's quality.
- Quality Aftermarket (e.g., Standard Ignition, Dorman): These brands are well-known in the aftermarket and produce entirely new parts, not remanufactured ones. They are designed as direct-fit replacements and often provide a good balance of quality and value.
- Remanufactured (e.g., Cardone): Remanufactured parts can be a budget-friendly option. They are original units that have been disassembled, cleaned, and rebuilt with new components. However, for a critical electronic part like this, some mechanics prefer a 100% new unit to ensure all potential failure points are addressed.
Pro Tip: Perform a Relearn Procedure
After installing a new throttle body, you must perform a relearn procedure so the car's computer can calibrate to the new part. You can do this without special tools. Turn the ignition to the 'ON' position (without starting the engine), slowly press the accelerator pedal all the way to the floor over 10 seconds, and then slowly release it over another 10 seconds. Turn the ignition off, and the procedure is complete.

Frequently Asked Questions (FAQ)
Is it difficult to replace the throttle body myself?
No, this is a job many DIYers can handle. It is easily accessible at the top of the engine. The process involves removing the air intake hose, disconnecting one electrical connector, and removing four 8mm bolts. The entire job can typically be done in under an hour with basic hand tools.
Should I buy a new or a remanufactured throttle body?
For this specific part, a new unit is generally recommended. Because the original failure is electronic, a new part from a quality aftermarket brand like Hitachi or Standard Ignition ensures that all components are fresh and potentially updated to prevent the original issue from recurring.
What happens if I don't replace a failing throttle body?
Continuing to drive with a faulty throttle body is not recommended. The vehicle can enter limp mode at any time, which is dangerous in traffic or on a highway. Ignoring the problem can lead to stalling and unpredictable engine behavior, making the vehicle unreliable and unsafe.
Can I just clean my throttle body instead of replacing it?
While cleaning can solve some issues related to carbon buildup causing a sticky throttle plate, it will not fix the common electronic failure in these Ford units. If your car is going into limp mode and showing codes like P2111 or P2112, the internal electronics have likely failed, and the entire unit must be replaced.
