Symptoms of a Faulty or Faulty Power Steering Pressure Sensor

If you notice your engine slowing down, stalling, or accelerating and then slowing down, check and replace the power steering pressure sensor.

The power steering pressure sensor communicates with the computer, sending information about the fluid in the vehicle's power steering pressure system. From there, the computer regulates the engine as needed. The switch has two electrical sensors as well as a diaphragm that is exposed to daily heat. Over time, this heat can cause the pressure switch to fail. Below are a few symptoms to look out for if you suspect a bad power steering pressure sensor:

1. Engine deceleration

Once the power steering pressure sensor begins to fail, the computer will not be able to keep up with the demands of the power steering system and make proper adjustments. One symptom of this is that the engine slows down when you turn a corner or when you drive at low speed.

2. Engine stalls

Along with slowing down, the engine may stall when turning the steering wheel. Again, this is because the computer is unable to meet the changing demands of the power steering system, causing the engine idle to drop too low. The engine computer does not recognize the need for power and therefore cannot compensate for it, causing the engine to stall. If this happened to you, contact AvtoTachki specialists to diagnose the power steering pressure switch. You cannot drive a vehicle if it has stalled.

3. Acceleration and deceleration

As the computer tries to keep up with the power steering system, you may notice the engine slow down and then compensate by accelerating at an erratic idle. This can be dangerous because a sudden increase in speed in a traffic jam could result in an accident or loss of vehicle control.

4. Check Engine light comes on.

If the computer detects that the pressure switch is not working properly, the Check Engine light will illuminate on the instrument panel. Once this light comes on, it is important to have your vehicle inspected by a mechanic as soon as possible. The Check Engine Light can mean many different things, so it could be a problem with the power steering pressure sensor, or it could be a combination of problems.

As soon as you notice your engine slowing down, stalling, or accelerating and then slowing down, check and replace the power steering pressure sensor. Also, every time the Check Engine light comes on, your car needs to be inspected by a mechanic.
