Hello, Im trying to figure out the next step in fixing my speedo and flashing "OD OFF" light. The speedo doesn't work for the first 5-10 minutes of driving and throws the code 42. If I clear codes while 80 is warm (while speedo IS working) and immediately drive it, the speedo works and no OD off flashing. Odometer and Tripmeter work 100% of the time. Haven't tested out cruise yet as I don't want to damage anything driving on highway with transmission codes present.
So far, I...
Cleaned the grounds behind the intake, and under the intake.
Pulled Code 42, faulty speed sensor #1.
Replaced VSS#1
Still not working.
Tested new VSS per FSM and it tests good.
Should I pull and inspect the cluster next?
Has anyone had issues with the TCM?
Visible Wiring and grounds seem good, all other gauges on cluster work flawlessly (other than D light).
I haven't checked for melted wires by EGR yet..
I'm just trying to figure out what the best next move is. Thanks in advance for any info..
I've researched and researched on mud but it seems most related posts just end with no posts regarding a FIX.. they just end..
Thanks again.
