Hey dudes,
Almost 100 degrees and very humid in Chicago today, had some codes pop up:

P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
P0111 Intake Air Temperature Circuit Range/Performance Problem

Of course I am blasting the A/C as well. Do I need to worry about anything? Autozone checked the codes for me, can I clear it without the hand held device?

Thanks dudes

Humy, if this is the first time that these have popped up, I would say that you can clear them and then see if they come back. It is very possible that you sucked up a bunch of really hot air and that is playing hell with the car. Just keep the numbers written down some where so you can reference back to them should they pop up again or different codes pop up.

can I clear the codes without the hand held code reader? If not, will the guy at Autozone that read the codes be able to clear them? Or can only Jaguar clear them?

Get Autozone to clear them, then while you are there spend 50.00 and buy yourself a scanner, leave it in your glove box!!!! Seriously!! If you have the scanner you can scan and clear the codes yourself. And you will scan codes yourself.
