Frequently asked questions
What does C0475 mean?
C0475 stands for "Electric Steering Motor Circuit." This is a General Motors chassis code. The Power Steering Control Module (PSCM) monitors commanded versus actual current in the three-phase electric power steering (EPS) assist motor and sets C0475 when it sees a fault such as an open, a short, motor position outside the allowed tolerance, missing motor sensor trim configuration, or excessive rack travel. When it sets, the module typically shuts down steering assist to protect the circuit, so the steering wheel becomes very heavy while the vehicle remains fully steerable manually. It is seen on GM vehicles with electric power steering, including Chevrolet, GMC, Buick and Cadillac models.
What are the most common causes of C0475?
The most common causes of C0475 are: Failed electric power steering assist motor, Open, shorted, or chafed wiring in the EPS motor harness, Corroded or loose EPS motor connector / poor electrical connection, Weak battery, failing alternator, loose battery terminal or bad ground causing low system voltage (EPS needs a stable 9-16V and can draw very high current), Blown power steering fuse or fusible link, Faulty power steering control module (PSCM). The specific cause varies by vehicle.
How much does it cost to fix C0475?
Repair costs vary widely depending on the root cause and vehicle.
