Good Afternoon glad to be member, I need to know exactly where the IAT sensor/module is on a 2003 3.0 Jaguar X-Type. Would love to see a engine Bay diagram but have not been able to find one online.

Mass Air flow (MAF) Sensor
The mass air flow (MAF) sensor informs the ECM of the rate of air flow entering the engine by producing a voltage which is proportional to the rate of air flow into the engine. The voltage produced by the MAF sensor increases as the rate of air flow increases. The MAF sensor also takes into account the density of the air entering the air intake system so that it is possible to maintain the required air to fuel ratio, and to compensate for variations in atmospheric pressure.
Integral to the MAF sensor is the intake air temperature sensor (IAT) which measures the temperature of the air entering the air intake system. The ECM uses this information to compensate for higher than normal air intake temperatures.
