2004 Saturn Ion Power steering problem code C0475

  • 2004 SATURN ION
  • 4 CYL
  • FWD
  • 44,000 MILES
About every 40 miles car beeps, dashboard readout states powersteering and power steering stops working. Shut it off, turn it on and your good for another 40 miles. Took it to dealership, after 5 minutes, they said found code C0475 and recommended that the "steering column needs to be replaced, cost $ 1,000. I feel that is must be only a switch, or sensor that shuts it down. It operates perfect otherwise

My questions are: Do you think the steering column needs to be replaced. If so, is this a reoccurring problem with some history that I could go to bat with.
Do you
have the same problem?

The following diagnostics might be helpful if the vehicle exhibits the condition(s) described above. Use the appropriate recommendation based on what
Review Corporate Bulletin Number 05-02-32-002B to assure you do not have a blown 60 amp steering fuse. The fuse can be blown during improper jump starting of the vehicle on the HHR and ION. Check for this particularly for tow in conditions. DO NOT replace the steering column unless an internal short has been identified in the column that is causing fuse to blow.

Power Steering Warning Message on DIC with DTCs C0176 and C0476
This condition is often the result of excessive lock-to-lock turns of the steering wheel, causing the thermal protection in the Power Steering Control Module (PSCM) to take the steering motor temporarily off line. This is a normal operating characteristic of the system. DO NOT replace the steering column for this condition. Refer to Corporate Bulletin Number 06-02-32-002B for additional information.

First inspect the motor harness connection to the PSCM. If no connector problems are found, then replace the steering column as this is an internal motor issue.

Although the code(s) appear in the PSCM, these are communication codes and are not the result of a problem with the column operation or the control module. If the codes are in history, clear the codes and re-key the vehicle a few times to see if they come back. If they reappear, look for a communication issue from the BCM U2107 or ECM U2105 (wiring, connector, etc.) As the root cause. If the codes do not reappear after a test drive, return the vehicle back to the customer and DO NOT replace the steering column. This might help
