Coolant pressure sensor check!; Is your EDC at risk?

Hello all,

Unfortunately I come with this warning, after one of our members had a wretched case (I'm terribly sorry).
Vehicles involved are those with 3.0L and 2.3L engines - VGT turbine from the fourth generation, manufactured until March 2007. It is also possible to be involved the vehicles produced in 2005-2006 from the third generation.

On the coolant expansion tank was added a pressure sensor to protect the engine against overheating due to cooling circuit failure.
Sensors membrane was not compatible with the coolant and it leads to perforation. Coolant penetrates the sensor, then goes through wires and reach the connector at the EDC, where creates oxide, then short circuit. The effect is devastating, EDC breaks down and the related connector melts.
To prevent this check the sensor part number.
The improved (corrective) sensor has the part number: 69502214, aprox 20 pounds.

Will check as a matter of urgency tomorrow - having read derbywill's post, really urgently!

My 35S12 is May 2007, so perhaps borderline...

Thanks Bazil - You're the Man!

Unfortuanatly I don't think it was ever a recall ether so it's up to you to check the part number on the sensor. I think the first sign of the switch breaking down was when the vehicle was connected to a easy and it had a coolent pressure switch fault, But this error it not seem serious enough to put the EDC light on! It just sits there presant in the memory!
I've changed a few ECU's for this fault and loom connector+pins let me tell you they are a fidderly job!

Just checked my header today and guess what - no sensor at all!

Unless they've moved it...

This is a pic of my header tank.

The van is 2007 35S12 LWB.

Don't know whether to be glad or sad!

Did they remove the sensor from the post-March 2006 models all together? As far as I know, my van was produced in May 2006.

My van is 2008 and has the sensor, but it is the new upgrade one.

the guys mentioned the problem is specific to 3.0 and 2.3 engines, what engine size is yours?

Price of new ecu is 740 then a code card at 140 then 90 to programme then if you haven't got your original code for your van a further 240 for you iveco dealer to ask iveco for the said code all plus vat now are we getting ripped off I think so so check that sensor before its too late

My July 2006 3rd gen 50c14 (3.0Ltr) has a sensor with the number 504181087 on it. Should I replace it with the newer number or does it only concern models with vgt turbo?

Thanks

Hi,

Yes you should! It involves all the vehicles which have this sensor.
