The P0554: Power Steering Pressure Sensor Circuit Intermittent code indicates that the engine control module (ECM) has detected an intermittent signal from the power steering pressure sensor. This sensor monitors the hydraulic pressure in the power steering system and helps adjust engine idle speed during low-speed maneuvers. An intermittent signal may result in inconsistent steering performance.
P0554 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0554: Power Steering Pressure Sensor Circuit Intermittent |
| Is it serious? | Yes, as it may cause erratic steering performance, especially during low-speed maneuvers. |
| Possible causes | – Faulty power steering pressure sensor – Loose or corroded connections – Faulty power steering pump |
| How to diagnose? | – Test the power steering pressure sensor – Inspect and secure connections – Check the power steering pump |
P0554 Meaning
The P0554: Power Steering Pressure Sensor Circuit Intermittent code is triggered when the ECM detects that the signal from the power steering pressure sensor is inconsistent or intermittent. This can result in erratic power steering performance, making it difficult to control the vehicle during low-speed maneuvers. The issue may stem from the sensor, wiring, or a faulty power steering pump.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any related fault codes that may provide additional insights into the power steering system issue. | OBD-II Scanner |
| Test the Power Steering Pressure Sensor | Use a multimeter or diagnostic tool to check the signal from the power steering pressure sensor and monitor for intermittent readings. | Multimeter, Diagnostic Tool |
| Inspect and Secure Connections | Visually inspect the wiring and connectors leading to the power steering pressure sensor for signs of looseness, corrosion, or damage. Secure or replace as necessary. | Flashlight, Multimeter |
| Check the Power Steering Pump | Inspect the power steering pump for signs of malfunction, leaks, or inconsistent pressure. Replace if faulty. | Basic Tools, Inspection Mirror |
| Clear the Code and Test Drive | After performing repairs, clear the code using an OBD-II scanner and test drive the vehicle to ensure proper power steering performance. | OBD-II Scanner, Vehicle Manual |
| Recheck for Codes | Re-scan the vehicle after the test drive to ensure the P0554 code hasn’t returned. | OBD-II Scanner |
