Ford Taurus Fuel Pressure Sensor (2009-2019): A Guide to Symptoms and Replacement
Diagnose a failing fuel pressure sensor in your 2009-2019 Taurus and learn how to choose the right aftermarket part for the job.
- A bad fuel pressure sensor can cause stalling, hard starts, and poor performance.
- Always check for trouble codes first; P0190-P0194 are common for this issue.
- Taurus models with EcoBoost engines have two fuel pressure sensors (low and high pressure) that must be diagnosed separately.
- Check for an outstanding recall on the fuel pump module for 2013-2015 EcoBoost models, as it causes similar stalling symptoms.
Is Your Ford Taurus Stalling or Losing Power? It Could Be the Fuel Pressure Sensor
If your 2009 to 2019 Ford Taurus is experiencing issues like stalling, hard starting, or poor acceleration, a faulty fuel pressure sensor might be the cause. This sensor is critical for engine performance, and when it fails, it can cause a range of noticeable problems. Understanding these symptoms is the first step to getting your car running right again.
Top 5 Symptoms of a Bad Fuel Pressure Sensor
- Check Engine Light: An illuminated Check Engine Light is often the first sign. The PCM will store trouble codes, commonly in the P0190-P0194 range, when it detects a problem with the sensor's signal. 🎬 See how a mechanic diagnoses a P0191 trouble code.
- Hard Starting: The engine may take longer than usual to start or require multiple cranks to turn over. This happens because the PCM isn't getting an accurate pressure reading to provide the right amount of fuel for startup.
- Stalling and Rough Idle: The engine may stall unexpectedly, especially when coming to a stop or at idle. A fluctuating sensor signal can cause an unstable idle, making the engine feel rough or shaky.
- Poor Performance and Acceleration: You might feel like your Taurus is sluggish or hesitates when you press the gas pedal. The engine can't produce full power if the PCM limits fuel delivery due to an incorrect sensor reading.
- Worse Fuel Economy: If the sensor fails in a way that causes the system to run rich (too much fuel), you'll notice you're visiting the gas station more often.
Important Note for EcoBoost Owners: Fuel Pump Module Recall
Ford issued a recall (NHTSA Campaign 16V621000, Ford recall #16S31) for some 2013-2015 Ford Taurus models equipped with the 3.5L GTDI EcoBoost engine. The issue involves the fuel pump electronic module (PEM), which can overheat and cut power to the fuel pump, causing the engine to stall. These symptoms can be mistaken for a bad fuel pressure sensor. It is wise to check if your vehicle is affected by this recall.
Choosing the Right Aftermarket Fuel Pressure Sensor
When replacing the fuel pressure sensor, you have several aftermarket options. Quality can vary, so it's important to choose a brand that offers reliability.
- Premium Aftermarket (Bosch, Standard Ignition): Bosch is a well-regarded OEM supplier for many brands, including Ford, and their parts are known for quality and reliability. Standard Motor Products (Standard Ignition) is another established brand that generally provides a good fit and reliable function for this part. These brands are a solid choice for a long-lasting repair.
- Standard Aftermarket (Dorman): Dorman specializes in creating direct OE-replacement parts and sometimes even improves on the original design. While often a cost-effective solution, some user reviews for electronic sensors like this one suggest that OEM or premium aftermarket parts may have a longer service life.
- Economy Aftermarket (Global Parts, other private labels): These are typically the most budget-friendly options. While they can get your car back on the road, their long-term durability and the precision of their electronic components may not match that of higher-tier brands.
Pro Tip: EcoBoost Engines Have Two Sensors
If your Taurus has a 2.0L or 3.5L EcoBoost engine, it has a high-pressure direct injection fuel system. This system uses two fuel pressure sensors: a low-pressure sensor on the fuel line from the tank and a high-pressure sensor on the fuel rail on the engine. A diagnostic scan tool that can read live data is essential to determine which sensor has failed. Don't just replace one without proper diagnosis, as they are not interchangeable.
Cost of Replacing a Ford Taurus Fuel Pressure Sensor
| Part Type | Estimated Part Cost | Estimated Labor Cost |
|---|---|---|
| New OEM (Motorcraft) | $120 - $200 | $75 - $225 |
| New Aftermarket | $68 - $120 |
Note: Costs are estimates and can vary based on your vehicle's engine, your location, and the repair shop's labor rates.
Frequently Asked Questions (FAQ)
Where is the fuel pressure sensor located on my Ford Taurus?
The fuel pressure sensor is typically mounted directly on the engine's fuel rail. The fuel rail is the metal pipe that supplies fuel to the injectors. Depending on your engine (3.5L, 3.5L EcoBoost, 2.0L EcoBoost), its accessibility can vary. You may need to remove the engine cover or other components to see it.
🎬 Watch this video to help locate the fuel pressure sensor.Can I replace the fuel pressure sensor myself?
For a mechanically inclined person with the right tools, this is often a manageable DIY job. The process involves safely relieving the fuel system pressure, disconnecting the electrical connector, and removing two small bolts. 🎬 Watch this walkthrough on replacing the fuel rail pressure sensor. However, if the sensor is in a hard-to-reach spot, it might be a job best left to a professional.
My mechanic says my Taurus needs a high-pressure and low-pressure sensor. Is that right?
Yes, if you have an EcoBoost engine (2.0L or 3.5L), this is correct. These direct-injection engines have a more complex fuel system with two separate pressure sensors that monitor different parts of the system. The base 3.5L V6 engine without a turbo typically only has one sensor on the fuel rail.
What happens if I don't replace a bad fuel pressure sensor?
Ignoring a failing fuel pressure sensor can lead to more serious issues. You will experience persistent starting and performance problems. In a worst-case scenario, the engine could stall while driving, which is a serious safety risk. It can also lead to a rich or lean fuel mixture that, over time, could damage other components like your catalytic converter.
