What is a Power Steering Pressure Sensor (PSPS)?
The power steering system must maintain the correct pressure in order to work properly. The pressure regulating valve for power steering builds up pressure. However, this pressure must always be monitored. This is the function of the power steering pressure sensor.
The power steering pressure sensors are responsible for monitoring pressure levels and sending this information to an electronic control module (ECU). It also sends information to ECU about power steering requests. The ECU adjusts idle speed to compensate for the extra load caused by power steering. The engine and steering pump are subject to additional loads, particularly when parking the vehicle or driving at low speeds. The PCM uses information from the pressure sensor in order to control engine speed. It will illuminate a warning light on the instrument panel if it senses too much pressure.
The life expectancy of the power steering pressure sensor is not set. The power steering pressure sensor is active every time the ignition switch is turned on. It fails to work, and the vehicle’s power steering assist is lost.
Power Steering Pressure Sensor Malfunction Symptoms
The steering fluid is directly in contact with the power steering pressure sensor. The sensor can become damaged by these chemicals or excessive heat over time. These symptoms could be noticed in this situation:
- – A power steering fault lamp illuminates on your instrument panel
- – Illumination and operation of the engine fault lamps
- – Complete loss in power steering assistance
- – Intermittent Power Steering Support
- – Lower engine speed
- Engine stalling while idling, at low speeds or right/left turns
- Faulty gasket can cause fluid leakage from the pressure sensor
These symptoms can be detected by checking the power steering pressure sensor. Check for leaks in the power steering fluid hoses if it is absent. The high pressure side of your system is where the pressure sensor is located.
