alfa 156 2.4 jtd

156 crank position sensor location

Please Help!
My 156 2.4jtd has been difficult to start and has just started cutting out while driving. It will restart after about 15mins.
I have a new crank position sensor and I want to fit it. Trouble is I cannot find the location. I have looked at some threads and they say it should be at the back of the block underneath the starter motor, but I cannot find it. Just spent an hour under the car with a torch and i'm beginning to think my eyes are painted on.
Hope someone can help as I want my beast back on the road asap.

Ignore the above, just found it. I was wrong about how easy it would be. There is too much engine in there to make working on it easy.
I just hope that will cure my issues!!!!

Re: 156 crank position sensor location

hi mate, best got at from underneath whilst on a lift, think it would be a bit tricky laid underneath it is a tricky job but console yourself that you are on the right track to cure the problem as that is exactly how mine behaved, lost count of the times i had to sit listening to the radio for the engine to be able to restart, as you say around 15mins, such a relief when that little game ends, can't imagine what would have happened if i'd been on the motorway when it stopped

It'll be in a different place on a jtd....

I don't know for sure where the sensor is on a JTD but if its anything like the V6 or T/S its easy enough to replace.

Re: 156 crank position sensor location

on any engine it will still be in a position where it is able to read the flywheel, so the position cant vary very much. usually the starter motor area is a good place to start looking no matter which engine you are playing with.
