What vehicles are most commonly affected by P0553?
Commonly affected vehicles include the 2013-2017 Ford Fusion and 2014-2018 Chevrolet Malibu, among others.
How can I prevent P0553 from happening again?
Regular maintenance, including checking fluid levels and inspecting wiring for wear, can help prevent P0553 from recurring.
What is P0553?
DTC P0553 indicates a problem with the power steering pressure sensor circuit. This sensor monitors the hydraulic pressure in the power steering system, which is crucial for assisting with steering. When the system is functioning correctly, the sensor sends a voltage signal to the engine control unit (ECU) based on the pressure detected. If this signal is outside the expected range, the ECU will log P0553. This code is particularly common in vehicles like the 2013-2017 Ford Fusion and 2014-2018 Chevrolet Malibu. A malfunctioning power steering system can lead to difficult steering, increased effort to turn the wheel, and can even compromise vehicle safety. Ignoring this code could lead to further damage to the power steering system, resulting in costly repairs. Drivers should take it seriously, as unresolved issues can lead to complete steering failure, posing a significant hazard on the road. In summary, P0553 signifies that the power steering pressure sensor is not performing as it should, demanding immediate attention to ensure safe vehicle operation.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0553 is present:
- Check engine light illuminates and remains lit, indicating a fault in the power steering system.
- Steering feels heavy or stiff, especially when turning at low speeds, leading to an uncomfortable driving experience.
- Increased effort required to turn the steering wheel, often resulting in driver fatigue during longer trips.
- Unusual noises such as whining or groaning when steering, which may indicate power steering fluid issues or pump failure.
- Intermittent loss of power steering assist, making it unpredictable and potentially dangerous while driving.
Possible Causes
Most common causes of P0553 (ordered by frequency):
- The most common cause of P0553 is a faulty power steering pressure sensor, occurring in about 60% of cases.
- Another significant cause could be damaged wiring or connectors within the power steering circuit, which can lead to intermittent faults.
- A failed power steering pump can also result in improper pressure readings, so it’s vital to check its functionality.
- Less common but serious issues can include a malfunctioning ECU, which may not process sensor data correctly.
- Rarely, air trapped in the power steering system can lead to inaccurate pressure readings, necessitating a system bleed.
