P0315 After Installing New ECM
I had an issue with my old ECM so I bought a new programmed plug and play one for my ion. After plugging it in and doing the key lock relearn I got it to start and came up with a check engine light associated with the trouble code “P0315” crankshaft position variation system not learned. How can I fix this any help would be greatly appreciated! I am new to the forum and new to ion redlines in general.
