This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks there's a problem with the sensor that checks how hard you're turning the steering wheel. It's like when a video game controller isn't working right.
The P0552 code is triggered when the engine control module (ECM) detects a low voltage signal from the power steering pressure sensor circuit.
The power steering pressure sensor/switch monitors the hydraulic pressure in the power steering system. The ECM uses this information to adjust engine idle speed and fuel delivery for optimal performance. A low circuit signal indicates that the sensor is reporting a pressure lower than expected, which could be due to a wiring issue, a faulty sensor, or a mechanical problem in the power steering system.
• Check Engine Light is on
• Hard steering at low speeds
• Engine stalls when turning
• Faulty power steering pressure sensor
• Damaged or corroded wiring/connectors
• Low power steering fluid level

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check power steering fluid levels.
• Inspect and maintain wiring and connectors.
• Schedule routine vehicle maintenance.
Sensor Issue
• Avoid making sharp turns until the issue is resolved.
• Drive cautiously and have the vehicle inspected soon.
This repair may be covered under the vehicle's powertrain warranty if applicable.
This code has been commonly reported in vehicles with high mileage or those with a history of power steering issues.
Moderate – It is advisable to address this issue soon to prevent possible steering difficulties.
Driving with impaired steering can be dangerous. Ensure the vehicle is safe to operate before driving.
• Vehicle must be running.
• Steering wheel should be turned to simulate steering pressure.
The power steering pressure sensor is typically located on the power steering pump or the steering rack.
Q: Can I drive with a P0552 code?
A: It's possible to drive with this code, but it may affect steering performance, especially at low speeds. Get it checked soon.
Q: How do I reset the P0552 code?
A: After fixing the issue, use an OBD-II scanner to clear the code. If the problem persists, the code may return.
