Cleared some codes a few days ago. Got 1111, 1106 and 041. Think 1111 is a system pass, 1106 is Dual Alternator Lower fault or MAP Absolute Pressure Sensor Circuit Intermittent High Voltage...clueless here! And then 0410 is a Secondary Air Injection System Fault. Seems like that covers a lot of ground? Light came on again after about 60 miles of driving.

Cleared them and tonight it showed 1000 (no idea what that might be since I have found nothing so far on line about it) and 0410 again. Going to try to call the dealer to confirm the meaning of the codes but really unsure of where to start on these. Any suggestions? Runs pretty good but the cold idle seems a little fast.

I've found some code sites but those are new to me. I understand that the same code is used on different Jags for different things. But both those sites look great and will be useful. Don't know why in all the searches I've done I didn't hit them?
Thanks mucho!

Internet OBD11 decode sites are notoriously misleading when it comes to Jaguar DTC's, particularly with the possible causes. Far better to use the Jaguar lookup table.



P1000 and P1111 are not error codes. They indicate whether all OnBoard tests have been completed or not. You will always see one or the other.

Immediately after clearing codes, P1000 will show. After the appropriate number of drive cycles have been run to complete all OnBoard tests, this will be replaced with P1111.

410, 1106 1111 and 1000 ... replace solenoid, delay filter, air switching valve, MAP sensor and all vacuum hoses... ur good to go ... 1111 meaning you're done with the drive cycle.
