Power Steering Pressure Switch Guides

Power Steering Pressure Switch Buyer's Guide

Summary

  • One of the components that are critical to the operation of a power steering system is the power steering pressure switch.
  • The power steering pressure switch, also known as the power steering pressure sensor, is a device that sends a signal to the powertrain control module (PCM) whenever it detects a high-pressure condition in the power steering system.
  • Inside the sensor is a spring and diaphragm mechanism.
  • The spring pushes on the diaphragm, keeping the switch in the open position. When the pressure from the power steering fluid overcomes the spring, the switch closes and sends a signal to the PCM.
  • The power steering pressure switch is typically attached to the line in the high-pressure side of the power steering system. This is where the fluid from the power steering pump flows to the power steering gearbox or power steering rack.
  • An increase in the demand on the power steering system corresponds to increased load on the engine. Because these incidents happen at low engine speed, the extra load may cause the engine to stall. The power steering pressure switch prevents this by alerting the PCM of the increased demand in the power steering system.
  • A replacement power steering pressure switch may cost you anywhere between $10 and $300. You may purchase it individually or as part of a kit.

Power steering systems are designed to help drivers turn the steering wheel with less effort. They do this by adjusting the steering ratio and offsetting the additional steering effort needed to change the front wheel’s angle with pressurized fluid.

The operation of the power steering system is extremely important during low-speed maneuvers. Without it, the vehicle will feel heavy and become difficult to maneuver while making a sharp turn or pulling into a tight parking spot.

One of the components that are critical to the operation of a power steering system is the power steering pressure switch. Here’s a quick overview of what you need to know about replacing this part.

What is a power steering pressure switch?

The power steering pressure switch, also known as the power steering pressure sensor, is a device that sends a signal to a vehicle’s primary computer or powertrain control module (PCM). It does this whenever it detects a high-pressure condition in the power steering system. The switch is actuated by the pressure from the fluid flowing through the power steering lines.

Inside the sensor is a spring and diaphragm mechanism. The spring pushes on the diaphragm, keeping the switch in the open position. When the pressure from the power steering fluid overcomes the spring, the switch closes and sends a signal to the PCM.

Power steering pressure switch location

The power steering pressure switch is typically attached to the line in the high-pressure side of the power steering system. This is where the fluid from the power steering pump flows to the power steering gearbox (in heavy-duty trucks and older car models) or power steering rack (in late-model front-wheel drive vehicles and light-duty trucks).

What is the power steering pressure switch for?

The power steering pressure switch alerts the PCM whenever the hydraulic pressure in the power steering system exceeds the normal range. An increase in the demand on the power steering system corresponds to increased load on the engine. Because these incidents happen at low engine speed, the extra load may cause the engine to stall. The PCM will respond by increasing the idle speed to support the power steering pump.

How to tell if your power steering switch is bad

Diagnosing a bad power steering pressure switch can be difficult without the proper automotive tools and knowledge. To avoid misdiagnosing your vehicle and replacing the wrong part, it’s best to seek the help of a professional and get your car checked by a mechanic.

Here are some symptoms that may tell you when it’s time to take your vehicle to the auto repair shop:

Check Engine Light is on

Most modern vehicles are equipped with on-board diagnostic systems that log error codes whenever the PCM detects a problem in different vehicle systems. A power steering sensor switch malfunction may trigger an OBD-II code, such as the code P0551, causing the Check Engine Light to illuminate.

Reminder: There are thousands of possible trouble codes that can activate the Check Engine Light. To be sure that it was triggered by a faulty power steering switch, you’ll need to connect your vehicle to an OBD scan tool to retrieve the specific error code.

Erratic engine speed

Another sign that your power steering pressure switch has gone bad is when your engine noticeably slows down while steering at low speeds or while turning the wheel at idle. You may also experience engine stalling as the engine is unaware of the sudden demand for power. The PCM may also do the opposite and suddenly overcompensate—increasing engine speed when it’s not needed.

How much is a power steering pressure switch?

The cost of a power steering pressure switch will vary depending on your vehicle’s year, make, and model. A replacement power steering pressure switch may cost you anywhere between $10 and $300. You may purchase it individually or as part of a kit.

While shopping for a replacement power steering pressure switch, you may encounter terms such as OEM and OE replacement parts. OEM or Original Equipment Manufacturer parts are components manufactured by the automaker or any of its official third-party manufacturers. Meanwhile, OE replacement parts are made by any other aftermarket parts company.

OEM and OE replacement power steering pressure switches are functionally equivalent. This means that they function and fit the same as the genuine part you are replacing. On one hand, OEM parts are generally more expensive and may take weeks to order from an authorized dealership or retailer. OE replacement parts, on the other hand, are a great alternative if you want to get your car back on the road faster at a more competitive cost.

Switching From Old to New: How to Change the Power Steering Pressure Switch

If there are people who can attest to the importance of a power steering pressure switch,that would be the outdoor enthusiasts, especially those who own a Ford Ranger. Driving this heavy-duty truck off rough terrains tests the driver's maneuvering skills. The rocky, muddy, and slippery routes of an off-the-road-driving often twitch the front wheels making them unaligned. In this situation, the power steering pressure switch turns on and gauges how much pressure is needed to put the wheels back on track. It would be then easier for the driver to twist and turn the steering wheel.

An old and worn-out switch can no longer perform that job so you have to install a new one. This article tells you how to replace the power steering pressure switch in your Ford Ranger.

Difficulty level: Moderate

Tools:

  • Set of wrenches
  • Power steering fluid
  • Plastic container

Step 1: It is advisable to do this task when the engine is cool. If you just came home after a drive, wait for a few minutes to cool the engine down.

Step 2: Open the car hood and find the power steering fluid container. Drain the old and used fluid by releasing the lock ring of the return fluid line. Let the old fluid flow into a bottle or jar before disposing.

Step 3: Detach the pressure hose from the switch. Use a wrench to loosen the nut that holds it in place. Pull the hose out of the system.

Step 4: Disconnect the switch from the compression fitting. Remove the compression fitting then remove the power steering pressure switch.

Step 5: Get the new power steering pressure switch and place it in the pump. Reattach the compression fitting and make sure that it is hand tight.

Step 6: Reconnect the pressure hose on top of the switch. Insert the compression fitting back to its place. Tighten the assembly using the wrench.

Step 7: Attach the fluid line. See to it that the lock ring is properly placed to prevent leaks.

Step 8: Refill the power steering tank with the new power steering fluid. Refer to your car's manual to know the exact amount of fluid to put.

Just a tip:

  • Choose a power steering pressure switch that is compatible to Ford Ranger. There is no standard switch so check the specifics in your car's manual.
  • Be careful with the hoses when removing and reconnecting them. There are metal tubes attached to them so avoid twisting them.
