- This is an easy and affordable DIY repair, typically taking less than 30 minutes.

Symptoms of a Failing Power Steering Switch on a Bronco
When this switch fails, it can't tell the engine's computer to adjust the idle for the extra load of the power steering pump. The symptoms are most obvious at low speeds.
- Engine Stalling or Stumbling: The most common sign is the engine nearly stalling or dying completely when you make sharp turns, like when parking or navigating a tight trail.
- Rough or Erratic Idle: The engine idle may become unstable, dropping low or surging when you turn the steering wheel.
- Fluid Leaks: The switch itself can develop leaks. You might see power steering fluid dripping from the sensor or its electrical connector.
- Check Engine Light: A failed switch can trigger a Check Engine Light. On these OBD-I era trucks, you might get a Code 52, which points to an issue with this circuit.
Don't Mistake It for Other Problems
Idle issues on these Broncos can also be caused by a dirty Idle Air Control (IAC) valve, vacuum leaks, or ignition problems. However, if the problem happens specifically when you turn the steering wheel, the power steering pressure switch is a primary suspect.
Choosing the Right Aftermarket Switch
For a vehicle like the 1987-1996 Bronco, using a new aftermarket switch is a practical and cost-effective choice. The original Ford parts can be hard to find and expensive. Quality aftermarket brands offer reliable performance for this component.
Brand Quality Tiers
- Tier 1: Reputable Aftermarket (Standard Ignition): Brands like Standard Motor Products (SMP) are well-regarded in the industry. They have a long history of making quality electrical components and sensors that meet or exceed original equipment (OE) specifications. Forum discussions often recommend SMP as a reliable choice for replacement parts.
- Tier 2: Standard Aftermarket (True Tech): True Tech is another available brand that provides a functional replacement part. While there is less specific owner feedback available for this brand on the Bronco, it serves as a budget-friendly option that will restore the function of the system.
Pro Tip: Check the Connector
Over the years, the electrical connector on the harness side can become brittle or contaminated with fluid. While you're replacing the switch, inspect the connector and its wires. If it's cracked or damaged, it's a good idea to replace it at the same time to ensure a solid connection.

Frequently Asked Questions
Where is the power steering pressure switch located on a 1987-1996 Bronco?
You will find the switch threaded into the high-pressure power steering hose, which runs from the power steering pump to the steering gear box. It has a two-wire electrical connector attached to it.
Is this a difficult part to replace myself?
No, this is a good DIY job for a beginner. It typically requires basic hand tools like a wrench to unscrew the old switch. You will lose a small amount of power steering fluid, so have a rag ready and be prepared to top off the fluid level when you're done.
Are there any recalls for the power steering on my 1987-1996 Bronco?
No, there are no active recalls or Technical Service Bulletins (TSBs) from Ford or the NHTSA for the power steering pressure switch on the 1987-1996 Ford Bronco. Recalls you may see online are for much newer Bronco models.
Do I need to bleed the power steering system after replacing the switch?
A full system bleed is usually not necessary. Since you only lose a small amount of fluid, you can typically just top off the reservoir. After starting the engine, turn the steering wheel from lock to lock a few times to work out any air that may have entered the line.
