P0552 severity depends on the specific fault. While some causes are minor (e.g., sensor failure), others can affect performance or emissions. Diagnosis is recommended.

Can I drive with P0552?

Short trips may be possible, but prolonged driving with P0552 active is not advised until the root cause is identified and repaired.

Will P0552 clear itself?

P0552 may clear if the fault is intermittent, but it will likely return if the underlying issue is not resolved. Use a scanner to monitor pending and confirmed codes.

P0552 - Power Steering Pressure Sensor Circuit Low Input

P0552 is a Diagnostic Trouble Code (DTC) indicating a fault related to Power Steering Pressure Sensor Input. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles. When P0552 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the Power Steering Pressure Sensor Input circuit or system.

What is P0552?

P0552 is a Diagnostic Trouble Code (DTC) indicating a fault related to Power Steering Pressure Sensor Input. This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles.

When P0552 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the Power Steering Pressure Sensor Input circuit or system.

Common Symptoms

Check Engine Light on
Component not functioning
Intermittent operation
Related system failure

Possible Causes

Open, short, or high resistance in wiring
Failed component/sensor/actuator
Corroded or loose connector
ECM internal driver fault

Step-by-Step Diagnosis

Connect an OBD2 scanner and confirm the code is present. Note any additional codes.
Review freeze frame data to understand engine conditions when the code was set.
Visually inspect the Power Steering Pressure Sensor Input and related wiring harness for damage, corrosion, or loose connections.
Perform a wiggle test on wiring while monitoring live data (if applicable).
Use a multimeter to check sensor/actuator resistance, voltage, and ground integrity.
Compare live data readings to factory specifications.
If circuit-related, trace the wiring diagram and test for opens, shorts, or high resistance.
Clear the code and perform a road test to verify repair.

Recommended Repairs

Replace or repair the faulty Power Steering Pressure Sensor Input if testing confirms failure.
Repair any damaged wiring, connectors, or terminals. Ensure proper routing and secure mounting.
Clean components (throttle body, MAF sensor, EGR valve) if contamination is present.
Update ECM/TCM software if a technical service bulletin (TSB) applies.
Replace related fluids (transmission fluid, coolant) if degraded or incorrect.
Verify repair by clearing codes and completing an extended road test under various conditions.
