Where is the pressure sensor on a power steering pump?
Fortunately, the power steering pressure switch will prove relatively easy to replace. You can find it by following the lines from the power steering pump to the steering rack or steering gearbox. You will find the pressure sensor attached to the line near the rack or gearbox.
What does the power steering pressure switch do?
The system pressure drops, the pressure no longer overcomes the spring pressure on the diaphragm, and the switch opens. The power steering pressure switch feeds information about demand on the power steering system to the vehicle’s computer.
How do you replace a power steering sensor?
Secure one side of the end wrench to the bottom of the hydraulic line and the other to the actual sensor switch. Hold the bottom wrench in place as you loosen the top power steering pressure switch. Once you get it loose, you should be able to hand screw the power steering pressure switch off the hydraulic line.
What causes a power steering switch to fail?
The switch has two electrical sensors, as well as a diaphragm, which are subjected to heat on a daily basis. Over time, this heat can cause the pressure switch to fail. The following are a few symptoms to look for if you suspect a failing power steering pressure switch:
What does the high pressure side of the steering pump do?
The high-pressure side feeds fluid from the power steering pump to the power steering gearbox or the power steering rack. Most heavy-duty trucks and many older cars were designed with a power steering gearbox, but front wheel drive vehicles and most new light duty trucks utilize a power steering rack.
How does the power steering pressure switch work?
The power steering pressure switch communicates with the computer by sending information about the fluid in the power steering pressure system of the vehicle. From there, the computer adjusts the engine’s operation as needed. The switch has two electrical sensors, as well as a diaphragm,…
What are the symptoms of a bad power steering pump?
The most common symptom you will experience is when you have difficulty turning the steering wheel. When you go to make a turn, the steering wheel will feel very stiff and you’ll have to use a lot of strength and force just to make a basic turn. This should prompt you to check the power steering pump because it could mean that it needs replacing.
