Power Steering Control Module Fault
A fault has been detected in the power steering control module.
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 control module is having trouble, which can make it harder to steer because it can't adjust assistance correctly.
What the computer is actually seeing
The control module sees a fault in its internal circuits or loses communication with other steering-related modules, typically showing a voltage out of range for its operation.
What a healthy reading looks like
Normal operation should show a voltage between 0.5V to 4.5V when measuring at the power steering control module's input. If values wildly fluctuate or stay at 0V, that's a red flag.
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.
- 11. Check the power steering fluid level. Ensure it's at the correct level as specified by the manufacturer.
- 22. Inspect wiring and connectors to the power steering control module for corrosion or damage. Fix any issues found before further testing.
- 33. Using a multimeter, measure the voltage at the power steering control module input. It should show between 0.5V and 4.5V. If it's out of range, continue diagnostics.
- 44. If the voltage is correct, use a scanner to check for additional codes and perform any necessary troubleshooting based on those codes.
- 55. If necessary, replace the power steering control module only after confirming all power and ground connections are solid.
Common causes
- Wiring issues or damaged connectors to the power steering control module
- Faulty power steering control module
- Low power steering fluid levels causing faults
- Electrical interference or shorts affecting module behavior
Typical repair cost

Frequently asked questions
Is it safe to drive with this code?
It's drivable, but steering assistance may be impaired. It's best to address it soon.
Will this code come back after clearing it?
Yes, if the underlying issue isn't fixed, it'll likely come back.
Why does this code show up alongside other steering codes?
Steering systems often share components or data, so faults can affect multiple sensors/modules.
