P0554 Power Steering Pressure Sensor Circuit Intermittent
Definition: The OBD2 code P0554 indicates an intermittent issue with the power steering pressure sensor circuit. This means that there is a sporadic problem in the electrical circuit of the power steering pressure sensor, which can affect the vehicle’s ability to monitor and adjust power steering pressure accurately.
P0554 – Power Steering Pressure Sensor Circuit Intermittent
Typical Severity: Moderate
Common Causes
P0554 – Power Steering Pressure Sensor Circuit Intermittent
Common causes:
- Faulty power steering pressure sensor
- Loose or corroded electrical connections related to the power steering pressure sensor circuit
- Intermittent wiring issues in the power steering pressure sensor circuit
- Low power steering fluid level
- Faulty power steering pump
Common Misdiagnosis
OBD2 Code: P0554
Description: Power Steering Pressure Sensor Circuit Intermittent
Common Misdiagnosis: Replacing the power steering pump or pressure sensor without checking for wiring issues or loose connections.
Common Diagnostic Steps
OBD2 Code: P0554
Description: Power Steering Pressure Sensor Circuit Intermittent
- Check the power steering fluid level and ensure it is within the recommended range.
- Inspect the power steering pressure sensor for any visible damage or corrosion on the connector and wiring.
- Test the voltage at the power steering pressure sensor using a multimeter to ensure it is receiving proper voltage from the ECM/PCM.
- Examine the wiring harness for any signs of wear, fraying, or disconnection that may cause intermittent signals.
- Use an OBD2 scanner to clear the code and perform a road test to see if it returns, indicating an intermittent issue.
- If equipped, check for Technical Service Bulletins (TSBs) related to this specific code and vehicle model.
- If necessary, replace the power steering pressure sensor with a new one that meets OEM specifications.
