Code P24C4
Hello, I just re-flashed the ECM back to stock from the mild Kennedy tune (which I love) in hopes of passing the new annual inspection here in MA. I'm getting this P24C4 code and it appears to be a bad value from an EGR valve position sensor. I'd appreciate any input and I will be emailing Kennedy Diesel later on tomorrow. Any one in MA with full delete and success at the inspection station please let me know. They are serious here now about it. They plug into the OBD port with their state computer, multiple pics of VIN and plate. If you're in a state with little or no emissions inspections, be grateful. It's a disaster here.
Thanks in advance and Happy St Patricks Day.
