How to replace camshaft sensor and where is it located on a 2003 Jaguar s type 3.0

Two sensors one for each camshaft. End of cylinder head.

Camshaft Position Sensor
The camshaft position (CMP) sensor detects the position of the camshaft. The CMP sensor identifies when piston No. 1 is on its compression stroke. A signal is then sent to the powertrain control module (PCM) and used for synchronizing the firing of sequential fuel injectors. The Coil On Plug (COP) Ignition applications also use the CMP signal to select the proper ignition coil to fire. The input circuit to the PCM is referred to as the CMP input or circuit.
There are two types of CMP sensors: the three pin connector Hall-effect type sensor (Figure 25) and the two pin connector variable reluctance sensor



and next the location of 2003 ford focus camshafts position sensor

DON'T USE WD40 on the air intake this will destroy the Lambda sensors,

hope it helps

most cam position sensors are located in the distributor of an engine. if you have a direct ignition system then the sensor can be located on the cylinder head either front or back... your engine is the same as a ford 4.0 liter...

I haven't finished this page yet so it's only a guide to location at the moment. location 5 and 6.

If you disconnect the sensor and check your error code you will be able to tell which is which (if you get a new code its the wrong bank).
It may pay to check your spark plugs in the bank concered, if the resistance of plug(s) go high this will also cause this fault

replace cam sensor

Check the igniter module.
I assume you have a ecu code telling you #3 coil is missfiring ?
If so also check the crankshaft angle sensor .
If it is not an error code do a compression test and check the injector.
Hope this helps

If your car is a 4.0L there are no camshaft sensor. Only crankshaft sensor and timing sensor. Dont know your problem but if your car is not running it is very common that the crankshaft sensor is faulty. It is fairly easy replaced and located just above the crankshaft wheel atthe front of the engine. It is mounted with one 8mm boult.

Map sensor is at the back of the intake manifold.
