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.
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 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.
What is the function of the power steering pressure switch?
The power steering pressure switch’s function is to tell the vehicle’s computer when the power steering system exceeds it normal operating hydraulic pressure. If the pressure is exceeded, the computer will raise the idle speed of the engine to prevent it from stalling.
What does the power steering pressure switch do?
The power steering pressure switch feeds information about demand on the power steering system to the vehicle’s computer. At low speed, such as during parking lot maneuvers, the engine produces little power.
What does a power steering pump sensor do?
The power steering pressure sensor, also referred to as a power steering pressure switch, gives your vehicle’s computer information about the demand being placed on the power steering system. The power steering system uses hydraulic pressure generated by a pump which is driven by the crankshaft via a belt.
Where is the power steering pressure switch located?
Ronald, The power steering pressure switch is located on the steering rack of the vehicle. Here is a link showing the location (number 13 in the diagram I believe) If you are getting fluid pumping out of the pump reservoir, then its either overfilled, or there is an air bubble present in the system.
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 to do if your power steering switch is faulty?
If this situation occurs, the faulty power steering pressure switch will give a few warning signs, such as the Check Engine Light coming on and sluggish steering when driving. Step 1: Disconnect the battery and lift the vehicle.

Why do I have to replace my power steering pump?
The reason for this likely has to do with a bad power steering pump that is making the belt inside the system slip. This means you must replace the pump and realign your belt. This is the worst noise of them all.
