When the sensor detects a high input signal, it means that the pressure in the power steering system is higher than the expected range, which can lead to issues with steering performance.
Common Causes of P0553 Mercedes-Benz
- Faulty power steering pressure sensor
- Damaged or corroded wiring in the sensor circuit
- ECM malfunction
- Low power steering fluid level
- Power steering pump failure
Symptoms of P0553 Mercedes-Benz
- Stiff or heavy steering feel
