What is the P0552 fault codes? What is the description of Power Steering Pressure sensor circuit low input malfunction? How do I fix the P0552 fault code What are the causes and symptoms for the P0552 fault code
What is the P0552 fault code? What does it signify?
A code P0552 is triggered when the powertrain control module, (PCM), receives a voltage signal via the power steering pressure circuit at a voltage below the manufacturer’s set parameters. This problem is most common at low speeds. The check engine light will be triggered. The check engine light must be activated if the fault occurs on more than one occasion in order for it to work.
Before the invention of hydraulic and electrically assisted steering, manufacturers used rack-and-pinion steering systems. The vehicle’s ability to steer at low speeds with these systems was inefficient and extremely laborious. This is why power steering was invented.
What causes the P0552 Fault code?
The following are the most frequent causes of the P0552 fault code:
- – Damaged or melted wires, snapped, corroded, shorted, open, or shorted and/or loose, corrosioned connectors to power steering pressure sensor
- – A blown fuse, or faulty relay
- – Use low or no power steering fluid
- – Power steering fluid not according to specification
- Fluid leakage in the power steering system
- – Defective pressure sensor/switch for power steering
- – A defective power steering pump
- – Broken or worn rack and pinion gears
- – Faulty PCM and other control modules (rarely).
What are the symptoms of P0552 malfunction code?
You may experience the following symptoms if your vehicle has the code P0552:
- – Illumination for the check engine light
- – Power steering fluid leaks
- When the engine speed is low, the engine could stall.
- Hydraulic assistance can be lost at low speeds, and it may become difficult to turn the steering column.
- – Increased fuel consumption
- – Uneven idle speed
- – Wistling, moaning, and knocking sounds coming from the power steering
How to Fix the P0552 Fault Code
It is common to mistakenly believe that the engine is stalling at low speeds while you drive and turn. The problem is in either the power steering pressure sensor circuit of the power steering systems.
Some of the possible repairs that can resolve the P0552 fault codes are:
- – Topping up and checking the power steering fluid
- – Replacing inaccurate or dirty power steering fluid
- Repair damaged, snapped or corroded cables or connectors to PSP sensors
- – Check the power steering pump and replace it if necessary
- – How to fix power steering fluid leaks
- – Replacing a faulty relay or fuse
- – Inspect the rack and pinion gears, and replace them if necessary
- – Replacing a defective power steering pressure sensor
- – Check the PCM for damage and replace it if necessary
How serious is the P0552 fault code?
A vehicle with a P0552 fault codes can experience the most serious problems, such as loss of hydraulic support or the vehicle becoming manual. Manual steering can be difficult for most drivers because they are not familiar with it. These codes can cause vehicles to stop at low speeds. It is important to address the problem as soon as possible and get it fixed as soon as possible.
