Reply To: 2017 Chevy Spark Engine Codes

You have 2 separate issues. The noise could be a bad bearing on the alternator or it could be just the belt. Have them replace the belt first and see if the noise goes away. But that has nothing to do with the codes. Those codes mean the PCM (ECM) needs to be reprogrammed. Some independent shops can do the reprogram but no idea if the shop it’s at can do that. If not, it needs to be done at a dealership (or a shop that can do it). As for the cost of replacing the alternator . . . the part itself is only roughly 30% of the total cost. Labor makes up the bulk of it because of it being buried. I don’t know about a Spark but in some cases you have to remove the wheel and the strut just to get to it. Good luck
