2005 Corvette Convertible, 42,000 miles needed an ECM Replacement. The dealership let it sit for weeks and did nothing. I ordered a remanufactured ECM and replaced it myself. The ECM was programmed with my VIN #. The car seems to be running fine now. I just took a 1,000 mile trip with no problems. Today I thought I would use my handy dandy OBD11 scanner to make sure I did not have any codes. It has a stored P0315 code for crankshaft positioning system. No check engine light. I assume since it's stored, it is not active. Should I take it to another dealer and have them reset it? Advise appreciated. Thanks
