Cadillac ECM replacement
45

Asked by Alan Mar 16, 2023 at 02:28 PM about the 2000 Cadillac DeVille Sedan FWD

Question type: Maintenance & Repair

I have a 2000 cadillac deville that I believe needs a new ECM module. I have
read that when you do this, there is progamming needed. Can someone tell me
what needs to be programmed, and how difficult this is? The ECM is not
reading signal from the crankshaft position sensor, and I need to replace it.

Deville’s have a wiring issue with crankshaft position sensor when they get older, so make sure you have that issue taken care of before condemning the computer. I know cause I had one the same year as yours. Was on its second engine and transmission when it got wrecked.
