The ECU uses these readings to calculate fuel delivery, ignition timing and engine load. A faulty MAP sensor can cause poor performance, increased fuel consumption and engine management faults. Part number 1N1A-9F479-AA is used on Jaguar 4.2 V8 petrol applications and is commonly referred to as a MAP sensor. \u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePart Number:\u003c\/p\u003e\u003cp\u003e1N1A-9F479-AA\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eCommon replacement reasons:\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e* Engine management light illuminated\u003c\/p\u003e\u003cp\u003e* Poor engine performance\u003c\/p\u003e\u003cp\u003e* Rough idle\u003c\/p\u003e\u003cp\u003e* Loss of power\u003c\/p\u003e\u003cp\u003e* Increased fuel consumption\u003c\/p\u003e\u003cp\u003e* Hard starting\u003c\/p\u003e\u003cp\u003e* Fault codes relating to intake pressure or engine load\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eCompatibility:\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e* Jaguar S-Type 4.2 V8 Petrol (2002-2004)\u003c\/p\u003e\u003cp\u003e* Jaguar S-Type 3.0 V6 Petrol (certain models)\u003c\/p\u003e\u003cp\u003e* May also fit Jaguar X-Type, XJ and XK models using part number 1N1A-9F479-AA.
