Help, I have a 2003 MPV. My check engine light came on and AutoZone checked the error code, it statedEVAP system LK Detect Pump Sens Circuit Range/perf P2404. Any ideas on how to fix this myself?

 

You will not be able to repair it yourself i am afraid. There is a TSB on that code which requires PCM reprograming. It may or may not require parts depending on the VIN range. It may or may not still be covered under warranty regardless of age/mileage.
