2003 dodge neon pcm
I replaced my pcm because of a po201 fault. I bought the
pcm online already programmed with vin and mileage.
After replacing I get 700, 715, 720, 344, 480, 562.
Speedometer is all over the place and will not shift out of
1st gear. Put original back in and I’m back to 201 along
with 700 and 562. Not sure where to go from there
