Ford Transit 2.4 TDCi 2007 - Non start, code for crank sensor #

Posted by John Sartain on January 20, 2015, 11:30 am

Year of Manufacture *: 2007
Engine Size and Code *: 2400
( Optional ) ECU Type: 6c11 12a650 al
( Optional ) Scanner Used: autodiagnos
( Optional) Fault Codes: crank sensor 335

Non start.

Flags crank sensor fault. Scoped signal at sensor, found to be ok. Have no wiring diagram. Struggling to work out what connector and terminal to measure signal.

ECU has three connectors which are 1)grey 24 plus 8 fatter pins,2) brown 40 plus 8 fatter pins and 3) black 24 plus 8 fatter pins.
can any one tell me which terminals to access please with my scope?
best regards john

Engine code is usually on the vin sticker on passenger b pillar, usually four digits like FIFA or something similar.

Are the bias voltages identical across both pins at the crank sensor

I believe the snappy troubleshooter has pin data for the ecu as well.

Can I ask, any issues with engine speed in live data?

Has it had a DMF lately?

Hi Anthony
there is no engine speed on live data.
my autodata has expired so info low
i will do another test at crank sensor with my fluke scope and report back.
best regards

With it at KOEO backprobe both sides of the sensor, both sides should have around 2v bias, this shows the sensor is not open circuit, if you have 2v one side and 0v the other the sensor winding is open circuit, bizarrely it still generates a signal on a scope.

thanks for your input anthony.
this did work but at only 1.7 volts.
found very poor connection at ecm.
the anvil lever and plastic cover is missing on the smallest block and the jelly/sealant has all gone sticky and runny and plastic bits falling apart.shuffling connector on ecm shows bad connection as vehicle starts now intermittently.
loom at other end at crank sensor is also poor. needs new loom.it is as if some nasty stuff has contaminated the top connecter. thanks for your help
best regards john
