I'm trying to get this car to pass the CA smog test. Last week I replaced the rear 02s. The readiness monitors for Cat, EGR and EVAP have not reset. I have had this car for about 2 months and the only time these monitors have reset was when I swapped the ecu for a day. I don't have the equipment to orientate the o2s for the other ecu so I changed back to the original as my problem seemed to be o2s related and not ecu. What does it mean that these readiness monitors will not reset? Is there something I can do? I have already gone through the Jaguar specific drive cycles many times but to no avail.
