On a 2000 ranger, if you change out the ECM will that mess up the PATS system and make it necessary to get a new key? My computer has been going haywire in my 2000 ranger. I have 3 or them, all 2000, and all 4wd. 1 of them is for parts. I was going to take out the ECM from the parts truck and replace my other faulty one. The issue is my check engine light comes on, then goes off. It keeps saying O2 problems and camshaft position sensor misaligned. Then it has random codes about circuit faults. It will run fine for a little while and then start missing and acting up. If I zero the computer, it works again. Now, my check engine light has completely stayed off, but the symptoms keep happening. I think my ECM is just jacked up. Anyways, will it hurt to swap them out?
