2005 tipper transit just stopped

[gsc1ugs]

Anyone help, i turned a corner and it cut out, i look at gauges, temp gauge was max, there is oil and water and engine wasn’t even hot, its 3 hrs later temp gauge still max, try to start fires for a second and cuts out, temp gauge varies from half to max. Ive had diagnostic xtool D8 on the van, no communication to van, I believe they dont have ecu this 2.4 diesel one but a PCM… no communication, could it be a fuse? Plenty fuel, water and oil. Im baffled

Your CHT (Cylinder Head Temp) sensor is done for, the PCM "thinks" the engine is overheating and is shutting the engine down to prevent further damage..

Mk6 machines are "NOT" OBD-II compliant, the Xtool D8 is OBD-II, so it and 99% of the newer readers won't work....you need Forscan onto it.

The D8 Xtool is very expensive and probably works fine on most OBD-II machines, but not on Mk6 Transits. Forscan is "FREE" to download and works perfectly on all Mk6 and later Transits.

What location is temp sensor please? Is it back of the cylinder head? What is best way to get to it?

Thanks for info

An update, i found the lead, looks like a nightmare to change, I unplugged the lead to try start, nothing, i then plugged lead back in, gauge acted normally, van started ….

Drove around gauge creeping up as it should, what do i do from here??? What is best access if i change sensor please?

You may have made good the connection on the connector - you may have moved the wiring (which could be broken) to make a good contact.
It takes about 7 mins for the engine to reach operating temperature whilst driving it.

The temp gauge is acting normally again but i cant risk breaking down so for what they cost was gonna fit a new one, i just need know best approach to get to it

You need a long "slotted" 15mm socket to remove and refit the sensor. As you've found, it lives on the back of the cyl head...pig of a thing to get at.

Sometimes you can get at it from underneath.

Great thanks i’ll edit solved but now its acting normally was it a bad connection?

[gsc1ugs]

Nowhere to click solved, should be a feature

[andz327]

you don't actually know if it was bad connection , nobody on here can answer that nut you, your the person working on it, bad connection, broken wire or faulty sensor, unless you've physically found the actual problem 100% then it's .....
HOPEFULLY SORTED

I need keep this open at moment because trying to locate this sensor as caused more headache, there are two pipes covering the sensor so impossible to get a socket on, has anyone changed one and what did you do about the pipes in the way?

Pipes...or hoses..?? The EGR Cooler lives around the back of the cyl head. Just remove the hoses to gain access if required.

They are pipes and me thinks they go to heater matrix
