This sensor converts the hydraulic pressure, which in this case is produced by the steering oil pump, into an electrical signal that is recorded by the vehicle's computer to accelerate the engine when high pressure is required to move the engine. the wheels. It usually occurs when the car is stopped or moving at a very low speed.
There are two main types of pressure switches, normally open and normally closed. For this application, which is to measure the hydraulic pressure, the sensor is normally open.
The problems associated with this sensor are not serious, but quite annoying, and these are:
Oil cans: As the hydraulic oil pump raises much more pressure than the engine, these sensors if they are of good quality tend to leak usually by electrical contact. It is necessary to change the sensor.
The engine shuts down when we use the steering: This is why the pump draws power from the engine to raise the pressure to move the steering of the vehicle, and if we have few RPM, the engine will tend to shut off. To avoid this, this sensor sends the signal to the computer with the pressure requirement and it is responsible for accelerating the motor so that it does not turn off.
Check Engine or Steering Light: On some vehicle models, the engine or steering light comes on. For this case the Chery A1, does not apply.
In this video I show you how to change it in a Chery A1 or Arauca.
