Question about 2002 Jaguar X-Type
Hello! Code P1111 is pointing at a defective air temperature sensor.
Jaguar does not have a code P1647. However if the code was in the P164x area it is an effect not a cause; The air temp. sensor controls fuel flow by sensing a differential in temperature; This device is called a MAP. A small black component with two mounting bolt holes with an electrical connector. It cost around $80 if purchased at an auto parts store. Follow back from your air filter towards the intake (need to remove plastic engine cover) to locate the MAP.
