Experienced mechanics share their insights in answering this question :
Hello. The pressure switch (or "sensor") on your vehicle supplies a signal to the engine computer to increase engine idle speed as the power steering line pressure increases. If the switch were bad, what you would notice is the engine stalling or idle speed dropping very low as you turn the wheel toward the extreme left or right position.
If the engine is not slowing or stalling when you turn the wheel, then the switch is probably OK. Among the causes of excessive steering effort are very low tire pressure, low power steering fluid or trapped air in the system, damaged or loose power steering belt, and damaged steering rack.

How to Identify and Fix Common car Problems ?

As soon as the power steering pressure switch starts to go bad, the computer will not be able to keep up with the demand of the power steering system and make proper adjustments. One symptom of this is the engine will slow down when you turn a corner, or while you are driving at low speeds.
If your vehicle is only hard to steer when you first turn it on, then you likely have a damaged steering rack. Often this problem will go away when the car warms up, and the rack becomes hot and well lubricated.
If a pressure sensor fails, it can cause the entire control system to fail and lead to inoperable equipment or system down time; depending on the type of system, significant damage can occur to the equipment and surrounding environment.
Your car`s power steering pressure switch monitors the amount of pressure in the system, and communicates that information to the car`s computer. If it notices a drop in pressure, the car`s computer may turn on a warning light in the dash.
While the engine is idling, turn the steering wheel to one side and measure the pressure. Then turn the steering wheel to the other side all the way and measure the pressure. Compare the obtained results with the specification. If the pressure is maximum at one end and low at the other end, replace the control box.
The steering angle sensor (SAS) determines where the driver wants to steer, matching the steering wheel with the vehicle`s wheels. Located within the steering column, the steering angle sensor always has more than one sensor packaged together in a single unit for redundancy, accuracy, and diagnostics.
The most common cause of a hard steering is there is not enough power steering fluid in the system. This will likely happen when there`s fluid leaking from a crack in the pressurized hose area, or if this area gets loose.
If power steering stiffness is still present after checking tires and fluids, you may have an issue with your steering rack. A sign of a bad steering rack is that steering improves the longer the vehicle has been running. A warmer vehicle is easier for lubricants to move around making the steering wheel easier to turn.
Symptoms of trapped air in the steering system can be a noisy, groaning pump or increased difficulty in turning the wheel. Running a power steering system with air in it is a good way to ruin a pump in a short amount of time.
While the engine is idling, turn the steering wheel to one side and measure the pressure. Then turn the steering wheel to the other side all the way and measure the pressure. Compare the obtained results with the specification. If the pressure is maximum at one end and low at the other end, replace the control box.
Driving isn`t recommended when you have a bad oil pressure sensor. You shouldn`t take it lightly, even if you`re confident it`s just an oil pressure sensor problem. Maintaining the correct oil pressure in your engine is critical to keep it functioning. A bad oil pressure sensor can give the wrong oil pressure readings.

power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.
Very loud pop when turning sharp left leaking transmission or power steering fluid where steering column meet rack
ANSWER : Hi there. If everything else has already been installed from the donor vehicle then it sounds like the high pressure hose is all that you need to install. The hardest part of doing this is the routing. One thing you may also want to double check is that the donor vehicle and your 2003 Escape have the same rack. There are different models depending on the model and the size of your wheels. You need to install the pressure line first, but if it does not line up then you may have the wrong rack installed.

Steering wheel is hard to turn – 2005 Nissan Maxim
ANSWER : As you may know, the power steering system is comprised of the power steering pump and the rack and pinion system down in the front underneath your car. These two systems work together with the use of hydraulic fluid being pumped through a series of valves in the rack and pinion system to create hydraulic pressure which is what you notice in the form of power steering assistance.
The rack and pinion pumps power steering fluid through a series of valves which then ultimately push the fluid to the power steering pump. When the fluid does not freely flow through the system, you may notice the steering to be a bit tough as you describe.
To avoid any unnecessary repairs, I would recommend having an expert from YourMechanic come to your location to diagnose your power steering system firsthand.
Steering wheel does not center
ANSWER : The problem to me sounds like you have worn out bushings that hold the power steering rack and pinion assembly. This is why your steering wheel gets off center in the direction of the turn. Have the steering inspected and the bushings replaced if they are bad. You should have no problems then.
Steering wheel is too hard to turn
ANSWER : The power steering gear box or the power steering pump are the two most likely causes of this issue. It is also possible that there could be a restriction in one of your power steering lines. A combination of these could also be possible. If the pump or gearbox failed, this can cause metal shavings to get into the fluid and could get trapped in the lines causing a restriction. I would recommend having your vehicle inspected by a qualified professional to determine the cause of your power steering issue. Consider YourMechanic as this can be completed at your home or office.
Hard to turn steering wheel when on park.
ANSWER : Hey there. There is a check valve in the power steering pump that quite often sticks after a rebuild. Since these are "restoration" components, they tend to sit on shelves longer than present-day parts. Tap lightly on the power steering pump housing and shaft with a hammer to "unstick" the check valve.
It is also possible that the control valve, which routes high pressure fluid to the "power assist" cylinder, is sticking or was not properly rebuilt. With this power assist system, which acts on the steering drag link to assist turning the front wheels, rather than through the gearbox itself – it is really irrelevant whether the steering gearbox is manual or power.
If you prefer some assistance with this issue, I would recommend having a steering system inspection conducted so that this issue can be repaired correctly.
power steering not working
ANSWER : You probably know this already, but I must mention that driving with the faulty power steering is very dangerous. This is definitely not an issue that can wait. The trouble could be in the power steering pump, belt/tensioner, or steering rack. Since you mention the previous mechanic was unable to find and fix the misfire, and unable to find and fix the power steering issue, it may be time for a new mechanic to take a look at the situation. A certified professional from YourMechanic can come to your car’s location to diagnose your power steering system and let you know exactly how to best proceed.
