I've seen other posts, where the RPD read no data available, but mine reads 0. I was sure I would have a code set for tmap (has GMS1 sensors and hann charge pipes), but no dtc's.
Any idea's?

I should mention, this is just the first of many bugs to be worked out on this project. I have done possibly one of the most insane (or just plain dumb) things one could do to a Cobalt. This car was an 06 2.4 SS. It now has the complete powertrain, suspension, brakes, wiring and interior from an 09 SS/TC. I am sure some have asked if this swap could be done easily and I'm sure they were told it would be easier (and maybe cheaper) to just buy the TC, and buying the SS/TC is the correct answer!! So, those of you who know exactly what I've done, are asking why? Well I'm an ex GM tech, the donor car (side impact write off) was cheap and I hads the time.

Sorry to be so long winded, just wanted you to know where I started, because I will have more questions!

 

I sounds like it has no feedback voltage.
