Hey I am getting this on my DIC...does anybody know what this code means???

 

That show's to be "Steering Sensor Bias Malfunction" H=History and C=Current. You can find all of the DIC codes here:

That could potentially explain your transmission behaviors. There's a synchronizing procedure that needs to be executed if the steering shaft was rotated for whatever reason while disconnected during your cam install.

 

DPC5,
Thanks for the link...I checked it and this is what it showed:

C1286 Steering Sensor Bias Malfunction

To the best of my knowledge the transmission is working fine now...don't have any problems with it (from what I can tell). What procedure needs to be done? I am taking it in for tuning on Monday...would this fix that problem???

 

This is a known glitch peculiar to '98 models - there's a TSB to cover the necessary reprogramming. I get this occasionally and simply reset the PCM.

 

So this is just a programming glitch? I have never seen it before until now...if I were to get LS1 Edit would this be able to fix that problem or woudl I have to take it to the dealership to get fixed. If that it the case, won't it wipe out any pcm programming I have done???

 

Yes, I saw your post about the tranny, very nice that it turned out to be something simple. There is a steering wheel position sensor plausibility test you can do with a Tech-II. It verifies that the analog voltages are as expected. If you have a scantool that can see the Steering Wheel Position Sensor Analog voltage parameter, look for 2-3 volts with the steering wheel centered and the wheels straight ahead. Something other than that and the steering shaft was probably rotated while apart.

I'm not aware of the TSB mentioned, it's worth a shot although since this showed up right after your steering shaft was disassembled I doubt it was a pre-existing problem.

 

What would that mean and do if it was rotated while it was apart? Does this just confuse the PCM or does this actually mess something up?

 

I just cleared the code but it keeps on popping up on the DIC. Do I need to take this thing to the dealership or something??? Or should I call the shop that just did my cam install???

 

The steering wheel position sensor generates voltages that indicate it's position. With the shaft in the correct position and the steering wheel centered it will show about 2.5v. As you rotate the shaft (i.e. turn the wheel) that voltage changes.

If you hook up a scanner and see that the center position is reporting some voltage that doesn't indicate "straight ahead" it means they hooked your shaft up incorrectly when they put things back together. Anybody that installs cams should be familiar with this issue. Your neighborhood GM service shop will certainly have a Tech-II scantool. If it were me I'd head back to the shop that did the work.

:smash:

 

There you go...that's what I needed to know...that way they will know what I'm talking about...if I just go in there and tell them that I'm getting error codes, they'll just tell me it's normal. I'll give them a call tomorrow...thanks.

Crap...how long does this take to fix???
