So after a whole bunch of diagnostic work, the shop I took my truck to told me I needed a new ECM. That whole saga is in another thread and the jury is still out on whether it solved my problem. However, what I noticed, via DashCommand, is that the new ECM, which is a reman supposedly, has the VIN of a 1997 Sierra with a 5.0L engine in it and I have a 97 Tahoe with a 5.7L. I don't care about the model, but the engine is a huge difference. I also am getting a P0137 (HO2S Circuit Low Voltage Bank 1 Sensor 2) now, which is completely new, although I'm hoping that's because it's confused.
So a few questions...
What kind of problems can that VIN mismatch cause?
If it was a reman, wouldn't the VIN be blanked out or something and need programming before working? Or is this just a junk yard pull someone is passing off as a remanufactured unit?
Lastly...what does it take to program the VIN into the unit?
