P0553 2007 Scion xB Code - Power Steering Pressure Sensor Circuit High Input

Quick Answer

The P0553 diagnostic trouble code (DTC) for a 2007 Scion xB indicates a problem with the Power Steering Pressure Sensor Circuit, specifically a high input signal. Common causes include Faulty power steering pressure sensor: The sensor may be sending incorrect signals to the ECM due to internal malfunctions, Wiring or connector issues: Damaged or corroded wiring connections can disrupt the signal between the sensor and the ECM, Power steering pump problems: A malfunctioning power steering pump can affect the pressure in the system, triggering the high input signal. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0553 2007 Scion xB Description

The P0553 diagnostic trouble code (DTC) for a 2007 Scion xB indicates a problem with the Power Steering Pressure Sensor Circuit, specifically a high input signal. The power steering pressure sensor is responsible for monitoring the pressure in the power steering system and sending this information to the vehicle's engine control module (ECM). A high input signal suggests that the sensor is detecting a pressure level that is above the normal operating range.
