P0552 Code: Meaning, Symptoms, Causes & Fix

Overview

Symptoms

• chassis warning indicator
• reduced stability control performance
• longer braking intervention

Common causes

• Open circuit in wiring affecting power steering pressure sensor circuit low input
• Broken terminal inside harness
• Connector pin damage/corrosion or harness stress near related components

How to diagnose P0552

1. Confirm P0552 and capture freeze-frame data with a professional scan tool.
2. Inspect wiring, connectors, and grounds related to power steering pressure sensor circuit low input for obvious defects.
3. Use a continuity test from module pin to component to identify opens/high resistance.
4. Check for related DTCs to identify the root-cause chain before replacing parts.
5. After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code P0552

Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.

Can you drive with P0552?

Most vehicles can be driven short-term with P0552, but postpone heavy load/highway driving until repaired.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

1. Repair obvious wiring/connector faults first to prevent repeat parts replacement.
2. Address the root fault mode (open) in the power steering pressure sensor circuit low input circuit/system.
3. Apply the required relearn/adaptation procedure if specified by service information.
4. Road-test and verify P0552 remains cleared under the conditions that originally set the code.

Fix options

• Repair open circuit and secure connector lock.
• Restore continuity and verify pin tension.
• Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$240-$1200

Common mistakes when diagnosing P0552

• Replacing parts without verifying voltage, ground, and signal integrity first.
• Ignoring related stored/pending codes that indicate upstream faults.
• Skipping post-repair verification drive cycle and readiness checks.

P0552 in common vehicles

P0552 appears across makes such as BMW, Mercedes-Benz, Audi, Volvo. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P0552?

P0552 is commonly set by open faults affecting power steering pressure sensor circuit low input.

How much does it cost to fix P0552?

For P0552, repair costs are typically $240-$1200 depending on exact root cause, labor rates, and part quality.

Can I clear P0552 without repair?

You can clear P0552 temporarily, but the code usually returns until the underlying fault is corrected.
