Need help with 28-TCS codes!!
I keep Getting Service Engine Soon, and 2 Codes under 28-TCS, they are as follows:
C1281 H Steering Sensor Uncorrelated Malfunction
C1286 C Steering Sensor Bias Malfunction
Had some work done on the car, could something not be connected? Hope its simple.

The steering rack had to be removed to install the camshaft.If the steering wheel was rotated with the steering shaft disconnected,the steering position sensor on the column will be out of synch :yesnod: Otherwise,faulty steering position sensors are somewhat common...

I did have a cam put in, so how would you correct this, I don't think its faulty all of a sudden.

When the steering link was disconnected the wheel was probably allowed to rotate and then not put back on in the correct position.
You need to center the wheels and disconnect the steering down at the gear box, then turn the steering wheel completely in one direction, now count how many revolutions it takes to turn the wheel in the other direction and then turn it half way back (you want to make sure that you get the wheel centered I.E. the same number of turns to the left as well as the right) now connect it back to the steering gear and your codes will not come back :cheers:

That wont work...With the steering disconnected,you can turn the wheel in either direction until eternity ;) The easiest way is to hook up the TECH2 and monitor steering position sensor voltage.When the steering wheel is centered and the wheels straight,the steering position sensor should read 2.5 volts.If it does not,than the column shaft was hooked up 180,360,540,720,etc out of snych :yesnod: Or of course,the sensor is faulty...

Lets just say it out of sync as that is most likely. What do I do exactly to correct it. Someone has to reinstall it at the correct angle?

Re: Need help with 28-TCS codes!! (runamuk)
I did have a cam put in, so I think we are right so far on that as to HOW it happened. Now, any and all details to fix it would be a great help. How to I re-center it?

Your probably going to have to take it back to the guy who did your cam install and have him reconnect your steering right :yesnod:

Re: Need help with 28-TCS codes!! (TexCorvette)
Any other advice? The dealer said its $400 to do it, plus $200 for a new sensor! So $600 for what!? Also, I don't have active handling, so what if anything does this do for my car? It drives fine, jus the annoying error.
I don't think the sensor is bad, it’s not a coincidence, just that the dealer finds this the easy way out. But lets just say I buy the sensor, or want to try re-aligning it, what do I do, is it simple? I have a mechanic friend, and he could help me out for much less if I can explain what it needs. Lets say it was put back out of align with a cam change, any steps one could list to fix it?

Tex,
I currently have the same problem. I was told by C4C5Specialist that I need a steering wheel sensor also. Fortunately, I have an extended warrenty to cover the work. I'm just waiting on an appointment. Check with C4C5Specialist on CAC forum. If anyone can give you the straight shoot he can.
Good luck.

Re: Need help with 28-TCS codes!! (TexCorvette)
First thing before you replace the sensor is to verify the ABS module harness is secure with the lever in the locked position. The ABS module is at the rear of my Vert near the differential. It was loose and the harness not fully seated. I replaced the sensor and still had a steering sensor uncorrelated malfunction, then I noticed that afternoon that the harness was not locked and secure. It has been over a month since the last SES light. :cheers:
