What is the P0553 fault code The description of an Input malfunction is Power Steering Pressure Sensor Circuit High How do I fix the P0553 fault code What are the symptoms and causes for the P0553 fault code
What is the P0553 fault code? What does it signify?
If the voltage signal from power steering pressure sensor circuit is higher than the manufacturer’s maximum level, the code P0553 will trigger. This problem is most common at low speeds. The check engine light will be triggered. Most vehicles will have the check engine light set if the fault occurred over multiple driving cycles.
Before electrically and hydraulically assisted steering systems were developed, manufacturers used rack and pin steering systems. These systems were inefficient and laborious, making steering the vehicle at low speeds very difficult. This is why power steering was invented.
What causes the P0553 Fault code?
These are the most common reasons that P0553 is triggered:
- – Damaged or melted wires, snapped, corroded, shorted or open wires, and/or loose, corrosion-prone connectors to power steering pressure sensor
- – A faulty relay or fuse.
- – Use low or no power steering fluid
- – Do not use power steering fluid that is not specified
- Fluid leaks in power steering system
- – Defective power steering pressure sensor/switch
- Defective power steering pump
- – Worn or defective rack or pinion gears
- Faulty PCM, or other control modules (rarely).
What are the Symptoms of P0553 Troublecode?
You may experience the following symptoms if your vehicle has the code P0553:
- – Illumination for the check engine light
- – Power steering fluid leaks
- Low engine speeds may cause engine to stall.
- Low speeds or when parking the vehicle can cause hydraulic assistance to be lost, making it difficult to turn the steering wheel.
- – An increase in fuel consumption
- – Uneven idle speed
- – The power steering makes a whistling, moaning and knocking sound.
How do I fix the P0553 fault code?
When fixing this code, the most common error is to assume that the idle air controller is responsible for the engine’s stalling when driving or turning at low speeds. The problem lies in the power steering pressure sensor circuit, or the power steering system.
There are several repairs that can resolve the P0553 fault code.
- – Topping up and checking the power steering fluid
- – Replacing dirty, or incorrect, power steering fluid
- – Repairing or replacing damaged, melted or snapped connectors or cables to the PSP sensor
- – Test and replace the power steering pump if necessary
- – Fixing power steering fluid leaks
- – Replacing a blown fuse, or faulty relay
- – Inspect the rack and pinion gears, and replace them if necessary
- Repairing a damaged power steering pressure sensor
- – Test the PCM and replace it if necessary
How Serious Is the P0553 Fault Code
A vehicle with fault code P0553 can experience severe problems, such as loss of hydraulic support or the vehicle becoming manual. The manual steering is often difficult for inexperienced drivers. These codes can cause vehicles to stop at low speeds. It is best to have the fault fixed quickly and promptly.
