Understanding the Power Steering Pressure Switch on Your Taurus
If you own a 1987-2002 Ford Taurus, you have a hydraulic power steering system. A key part of this system is the Power Steering Pressure Switch. Its main job is to prevent the engine from stalling when you turn the steering wheel at idle or low speeds. It does this by detecting the pressure increase from the power steering pump and telling the engine computer to bump up the idle, compensating for the extra load. When this switch fails, it can cause a few distinct and annoying problems.
Symptoms of a Failing Switch
A bad power steering pressure switch can cause symptoms that might seem unrelated to steering. The most common issues include:
- Engine Stalling During Turns: The most classic symptom. When you turn the wheel in a parking lot and the engine stumbles or dies, this switch is a likely culprit.
- Rough or Erratic Idle: The engine might idle roughly or surge up and down as the computer tries to guess the right idle speed.
- Power Steering Fluid Leaks: The switch itself can fail, leaking fluid from its housing or the electrical connector. This is a common failure point.
- Check Engine Light: A failing switch can trigger a Check Engine Light. A common trouble code is P0551, which points to a problem in the power steering pressure switch circuit.
Don't Ignore Leaks
A leaking power steering pressure switch will not only cause driveability problems but will also lead to a low fluid level. Running the power steering pump dry can cause permanent damage to the pump, leading to a much more expensive repair.
Choosing the Right Aftermarket Part
For a vehicle like the 1987-2002 Taurus, aftermarket parts offer a great balance of value and quality. The original OEM parts can be expensive or hard to find. Aftermarket brands like Standard Ignition and True Tech 🎬 Watch a detailed overview of the Standard Motor Products pressure switch. provide reliable alternatives.
- Standard Ignition (Standard Motor Products): Often considered a premium aftermarket brand, Standard parts are known for their quality control and durability. They often use high-quality materials like Viton seals to withstand harsh engine conditions. For a critical sensor like this, spending a little more on a trusted brand is often a good investment.
- True Tech: Often positioned as a more budget-friendly option, True Tech is a brand line from Standard Motor Products. While it may not have all the premium features of the main Standard line, it provides a functional replacement that meets original specifications and can be a good choice for a budget-conscious repair.
Check the O-Ring
Some replacement switches come with a new O-ring or thread sealant, while others do not. The original Ford switch often used a straight thread with an O-ring to seal. Always check if the new part requires an O-ring and ensure the sealing surface on the power steering line or pump is clean before installation to prevent leaks.

Frequently Asked Questions (FAQ)
Can I drive my Taurus with a bad power steering pressure switch?
Yes, but with caution. If the only symptom is a fluid leak that you keep topped up, it is less urgent. However, if the engine is stalling when you turn, it can be dangerous in traffic or during low-speed maneuvers. It is best to get it repaired soon.
Is this a difficult part to replace myself?
For most DIY mechanics, this is a straightforward job. It typically involves unplugging the electrical connector and unscrewing the switch from the power steering high-pressure line or pump. You will need a wrench (often 9/16" or similar) and something to catch a small amount of fluid that will leak out. The job usually takes less than 30 minutes.
Where is the power steering pressure switch located on my Taurus?
It is usually screwed into the high-pressure power steering hose. Look for a small sensor with a two-wire electrical connector attached to one of the metal power steering lines between the pump and the steering rack.
Are there any recalls for this part on my 1987-2002 Taurus?
No. Searches for recalls on the 1987-2002 Ford Taurus for the power steering pressure switch did not find any relevant results. Later model Taurus vehicles (2011-2013) had recalls related to electric power steering systems, but this does not apply to the hydraulic systems in the 1987-2002 models.
