I have been reading the forum for a few days -- lots of information.

I have a 2002 XJR with 48k -- Recently had my first problem with the car. The CEL came on with the following codes:

P1642 (Can Link) P1647 (O2 Sensor control chip bank #2) and P1111 -- also P1647 was listed again after the P1111.

I am a bit confused -- some say the sensors could be the problem -- but there are a bunch of codes that are all quite particular to the sensors and none of them are showing up.

Any ideas??
