Power Steering Control Module Performance
The power steering control module detected a performance issue.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The power steering computer isn't working right and may stop providing assist soon if not checked out.
What the computer is actually seeing
The power steering control module monitors inputs like steering angle and torque. If the input signals are outside of normal operating ranges, it triggers this code.
What a healthy reading looks like
Steering angle should be around 0° when driving straight, torque values around 2-5 Nm with normal input from the driver during turns.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check power steering fluid level—should be at the correct fill line.
- 2Inspect wiring and connectors to the power steering control module and steering angle sensor for damage or corrosion.
- 3Use a scan tool to check if there are other related codes present—document any additional codes before proceeding.
- 4Test the steering angle sensor while turning the steering wheel, ensure it outputs a smooth voltage change from 0.5V to 4.5V over the full range.
- 5Check the voltage at the power steering control module connector with the key on: should be 12V. If not, trace back to the battery.
Common causes
- Faulty power steering control module
- Electrical connector issue
- Low power steering fluid level
- Faulty steering angle sensor
- Worn out steering components
