Crank Sensor replacement - 1.9 JTD 156

Broke down Last night on the way home from work

Luckily I had my OBDII cable with me and using Fiat ECU Scanner found the fault was P0335
which is the much discussed on here Crank Sensor failure.

After 15 Minutes at the side of the M42 the AA turned up and car started first time.
As its a known issue that when warm the sensor fail's I was towed the 35 Miles home and set about researching today's job of fitting the new sensor.

I found the following guide which was perfect for my 156 1.9 JTD Sportwagon.

Fiat JTD crank/ RPM sensor removal and replacement - The FIAT Forum

Getting to the Sensor was simple, its the 3 cable clips involved that are a real pain in the Ar$e

Luckily I have small hands and the job was done in 2 Hours at a total cost of 33 for the sensor from my local Motor Factors.

I hope the Guide helps others who have this problem.

replaced the crankshaft sensor on my '06 159 last night, what a job!
it took a little over 2 hours, i shall tell you my findings!

use an old blanket or similar to "pad" the top of the engine, as it is not very comfortable to lie on.
remove the fuel filter and bracket from behind the engine, this gives you a few more inches to play with.
make sure you have long torx bits, (like an allen key set, not socket types) as they are needed to get into the securing screw.
keep referring to the new sensor to make sure you are pulling things the right way!
the sensor is located directly underneath the starter motor, a pain in the a** to get to!
once you have located the sensor, removed the electrical connection and loosened the securing screw, the actual changing of the sensor and finishing the job from now on isn't too bad.
disconnect the battery negative, (as you are near the starter motor and working "blind")

if you have any other questions then please just ask me and i will do what i can.
