this steering gear itself has a senor built into the gear that is service seperately, if the new gear you have does not have the sensor...then it may not be the right one, find out what the code for the failure is and if its related to that sensor you may just have a failure in that circuit

The new steering gear had the same sensor. Could it be the valve in the Power Steering pump is sticking. This would be the first Power Steering pump of all the cars I've had that has failed. Maybe debris from old hoses clogging it? Anyway, I will pull the pump and check it out, post the results.

Piper 909,

I have the same problem on my 1997 Eldorado...Service Steering System. Were you able to resolve it? If so, what was the fix? This can't be cleared until the problem is repaired, right??? Thanks for any advice you can send, mine just came on about a week ago. Thanks

I'm thinking it's has to be a bad wire to the magnasteer, my pump wasn't bad. Another member stated he thought the magnasteer wires were melted on the exhaust. I 'm going to check it more thoroughly. It's not that you can't drive it, just harder to steer at low RPM and a hassle to reset the info everytime you get in and drive.

Was it the wires to the magnasteer?

2 days ago the same exact thing happend to my 2006 STS. Steering went a bit tight and the Service steering sys light came on.

I tried pulling codes and couldnt get any. Took it to the dealer (out of warranty) and they didnt see any codes either. They said they would have to start trouble shooting the problem.

Thanks
Ralph

I don't think it's the wires to the steering rack. Read somewhere that radiator fluid could damage the connections in the brake control module, which the magnasteer wires feed into to. What I did notice is when we had a cold snap, the steering came back for a while. Intermittent problems can indeed be a "short", so I am going to finally pull the module apart, try cleaning it, and see what happens.

just had similar problem. 3 days ago i was turning right, i thought my car was dying, steering go tight but then was normal. then last night i was sitting in traffic light (straight) and light came on, i moved steering wheel all was normal. steering has been fine for going on 24 hours now, no codes showing up, no tight steer, yet. i will heck back this week to see if there is a definitive answer before i start pulling things apart. hope i get some go news later.
