Code 48 Stepper motor

Ok, so on the trip home with my new to me 95 D90 I got a check engine light, after checking the code reader it showed a code 48, stepper motor.

SO can I safely drive it with this issue?? All it does is adjust the idle, right?? Any tip on fixing it without replacement?

Thanks in advance for any help.

Safe to drive. Yes, you can clean it. That sometimes fixes it.

Ok, so after cleaning the stepper a few times, and resetting the codes (battery disconnect, code reader disconnect, then battery re-conn, reader re-conn.) and still getting a 48, I got a new genuine stepper, and still have the code.

So now I am trying to find the tests, and adjustments outlined here.....

check base idle speed- see setting procedure. Refer to tests 15 and 16 of continuity test procedure. Check road speed sensor- refer to test 25 of continuity test procedure.

I havn't been able to find them in the .PDF manual I have.

Did you do the reset procedure again after installing the new stepper? Otherwise, it may take awhile before it goes away 'on it's own'. I had this happen..

I did a reset, and got the 02 code for "reset computer" and then got the 48 back in a few miles.

If the stepper and it's wiring is good, than you've narrowed it down a lot.

Either your idle speed is out of the accepted range (700 +/- 50 I think)
Or the VSS, or it's wiring, is no good. The VSS is mounted down by the transfer case inline with the speedometer cable.

Also check the housing that the IACV is screwed into...they will come loose from the plenum and cause an air leak and code 48.
