P0550 - POWER STEERING PRESSURE SENSOR CIRCUIT MALFUNCTION

POST UPDATED IN November, 2020

Description of DTC code P0550 Generic

The hydraulically assisted system consists of a steering pump that is driven by a belt, plus a steering box, hoses or lines, and some sensors. The ECM (Engine Control Module) works in conjunction with the Power Steering Pressure Sensor (PSP) to control the pressure within the system. Besides, adjustments are made if necessary.

The Check Engine light is lit next to the DTC code setting P0550 OBDII when one or more conditions are identified which are outside the specified range for the PSP Sensor circuit. Usually, this code is due to electrical problems, but mechanical failures are not ruled out.

Symptoms of fault code P0550 Generic

  • MIL Lighting (Check Engine)
  • The engine is stagnant.
  • Driving problems.
  • Fluid leaks.
  • Difficulty in steering the vehicle.

Causes of OBD2 P0550 Generic

The reasons that influence the configuration of the error code P0550 OBD2 are

  • Electrical cables or connectors in poor condition.
  • Power steering can leak fluid.
  • Fuse or relay related to the burnt system.
  • Faulty Power Steering Pressure Sensor (PSP).

Possible solutions of the DTC code P0550 Generic

To solve the problems caused by the diagnostic code P0550 OBD2, you must take into account the following:

  • As a first step, check the level of the power steering fluid. If you notice that it is missing, you should reload it. Take into account if there are any leaks. Repair if there are any leaks present. You should also check the PSP Sensor for the presence of fluid that may contribute to fluid damage.
  • Check the status of the Power Steering Pressure Sensor (PSP). Check the service manual for indications. Use a DVOM (Digital Volt-Ohm Meter) to check each circuit. If you find inconsistencies, make the necessary repairs.
  • After locating the sensor, check the connector. If it has oil, it is due to leaks, clean it, and reconnect it. If the connector has corrosion, repair it.
  • Check the sensor for physical damage. If the lines are improperly adjusted, the sensor may be rubbing against another component causing an electrical problem.
