Would a more experienced XJR (X308) owner advise how to replace the LH timing cam sensor? V12 motor - no problem. This Supercharged V-8, another whole story!!! Ha Ha In advance, thanks for your help. Pictures would also be most appreciated.
If you have an intermittent or occasional failure, then check the cam cover bolt by the sensor.
It needs to be a different material to not cause issues to the sensor. If you look at the bolt head the by the sensor, it should have different numbers to the others.
My problem is I can’t find the sensor!!! That’s why a picture would be wonderful! I think I may be facing multiple failures. First the cam sensor and secondly, very slow cranking so I suspect the starter may require some attention.
The car started fine, ran for about 3 to 5 seconds then quit! Subsequent start attempts resulted in (a) slow motor cranking and (b) no start. Fuel pumps (both) were replaced less than 10,000 miles ago. When the motor does turn over the tach comes off the peg so I believe the crank sensor is OK.
I’m open to any other thoughts or suggestions. I appreciate the help.
Just found the Jaguar 870A training manual, complete with AJ26 and AJ27 illustrations. Looking from above the engine (facing forward) the AJ26 cam sensor is in the LH rear. Probably will have to remove components to access it!!! Oh Well.
My original motor suffered from a coolant leak, resulting in overheating. I purchased a 2000 X308 motor with tranny, only 30,000 original miles. I then had to convert the AJ27 to AJ26 specs for the ECM to work.
I’m an old dinosaur so all this computer controlled stuff just confuses me!!! LOL
One day the car started, ran for about 5 seconds then quit! Fuel pumps were replaced less than 10,000 miles ago plus I tested the fuel rail for pressure-- Ok. Then the motor started cranking very slowly. I think I may have multiple problems so first must confirm there is spark. My suspicion is the cam sensor. I have a new one in case I’m right!!! Ha Ha Just have to find where it’s located!!!
Thanks for your assistance.
To AndyK: I’ll definitely check the bolt but the car was running for a long time before this non-start issue came up.
