How much is repaired for cold POO01

Hello, two things. First of all the air conditioning concern has nothing to do with your diagnostic trouble code. The air conditioning system must be tested by a certified technician who is specialized and has credentials to test refrigerant and handle refrigerant. They can perform diagnosis and let you know what steps to take to repair this part. For the P0001 code, troubleshooting is needed to drill down to the root cause of concern. You did not indicate which engine your Dart is equipped with; but regardless -- the only notes I can see is that the concern is related to the fuel volume regulator -- but testing is required to know what's going on. https://repairpal.com/auto-repair-near-me That's a link to find quality shops near you.
