i have a 1999 jaguar xjr after working on my radio and reconnecting the battery i got code p1000 obd testing not complete, my pcm had been reset, after a couple of drive cycles i got p1111 obd testing is complete. its been a couple of weeks and the code is still there so i erased it and it went back to p1000 obd testing not complete, another couple of drive cycles and its p1111 again obd testing complete. i call the local jaguar dealer and they said p1111is the intake airtemp sensor. i asked him were all codes and definitionsthe same from 1999 to 2008, he didnt know. but i know jaguar has been brought out a copule of times once by ford and someone else, and i was wondering if that had something to do with the different code definitions? im using a obd2 code reader. can anyone help?
