P0553 OBD-II: Power Steering Pressure Sensor/Switch Circuit High
P0553 Severity
Will P0553 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0553?
The Power Steering Pressure Sensor tells the engine control module (PCM) that the engine idle speed needs to to be held at a specified level while the driver is operating the Power Steering System at slow vehicle speeds. This is because high levels of hydraulic pressure are needed from the Power Steering Pump in order for the Power Steering system to steer the vehicle at slow speeds. Creating this pressure puts additional load on the engine and commonly occurs when parking the vehicle. When the PCM detects an inaccurate or irrational signal, it sets code P0553.
