Power Steering Control Module Voltage Low
The power steering control module is reporting low voltage.
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 module isn't getting enough voltage to operate properly, which can make steering feel heavy or unresponsive.
What the computer is actually seeing
The power steering control module expects a voltage between 9V and 16V. If the voltage drops below 9V, it triggers this code.
What a healthy reading looks like
Normal operating voltage should be between 12V to 14.5V with the engine running.
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 the battery voltage; it should be 12V or higher with the engine off, 13.5V-14.5V running.
- 2Inspect battery terminals and connectors for corrosion or loose connections; fix as necessary.
- 3Examine wiring harness to the power steering control module for damage or shorts; repair/replace any damaged wires.
- 4Measure the voltage at the power steering control module connector; it should be 9V or higher; if it’s low, trace the wiring back to the source.
- 5If all checks are good and voltage is still low at the module, consider replacing the power steering control module.
Common causes
- Low battery voltage
- Faulty power steering control module
- Poor wiring or connector issues
- Corroded battery terminals
- Faulty ignition switch or relay
