The problem here is visually it would fool an onlooker. Most if not all (anybody with half a clue) would hook up to the ALDL connector under the dash and scan all 5 computers in the CRD. Any and all faults would be reported, CEL light or not.
Unless you have an Emissions Inspection with a Trained and Certified Inspector, I doubt if any of the various Government Employees would even let on they had the expertise to plug in a scanner and look for faults. Police would notice a CEL and issue a warning or other citation requiring you to get it fixed.
