My '99 has been surging and stumbling when first starting but runs fine after it warms up. I pulled the codes and the Jaguar specific code of 1111 says the voltage in my air intake temperature sensor is high.
Question - where is the sensor located? I know it is on the engine but??????
Thanks to all!

 

P1111 and P1000 are not Trouble Codes in a Jaguar.

P1111 (as used by Jaguar) is a Code that means All Emission Monitors Complete.

P1000 (as used by Jaguar) is a Code that means All Emission Monitors Not Complete.

Tne IATS is located in the same assembly with the MAF Sensor at the rear of the Air Cleaner. They both share a connector.

 

Try a can of BG-44K in a full tank of gas.
