Default Code P1111

I have a 2003 XJ8 Sport which occassionally comes up with a Failsafe Engine Mode reading. I took the car to Autozone and they said it was a P1111 code reading. I have been told that it could be related to an Intake Air Tempature Sensor but I can't even find that part listed for my vehicle. This problem only occurs randomly but when it does I have no Cruise Control. Any help would be gratly appreciated!!

Thanks,

Hi,

P1111 is not a fault code. It is a special designator Jaguar uses meaning system ready, drive cycles completed after the last fault event. P1000, on the other hand, means system not ready, or drive cycles not completed after the last recorded fault event.

Some OBD II Basics - All P0xxx codes are generic and uniform across all manufacturers and mean the same on every car. All P1xxx codes are manufacturer specific codes. You cannot use a generic code chart to analyze P1xxx codes for a Jaguar.

Next time your car displays an engine fault light, try reading the codes then. If you have a CEL illuminated and the only code read is P1000 or P1111, then you probably have a fault that generic code readers cannot see. Could be a chassis code, for example.

One last thing - Neither P1000, nor P1111 can be erased.

Hope this helps you.

Best,
