Does anyone know where NANOCOM reads the engine temprature. Is it the front sender unit on the head as my Nanocm does not read the water temperature above 60 c and im sure its running hotter than that but the car gauge is reading right in the middle if it is the front sendr unit does anyone know the part no
Thank you in advance

The sensor for the gauge is separate from the one for the EDC, if the gauge is in the middle, then the temperature is above 80C.
I can never remember but I think the sensor between cylinders 3 & 4 is for the EDC and the sensor between 1 & 2 is for the gauge. Easy to prove, unplug the front one.

as Datatek mentioned

Your running a diesel?

this is of more use my mate
Just to give you an idea of where to look.
The later m51 had three sensors, the one closest to the bulkhead is the last minute sensor when it puts the fans on... Normally too late late at that point.
The earlier engine has only two.
As our mate Keith says. One for the engine ecu and one for the gauge in the dash.
The engine ecu temp can cause other faults with fueling and delayed gear change issues.

Although very helpful kiddo, this image doesn't relate to his engine.

the no 10 is the one for the ECU and is colured green. the no 6 must be for the gauge and coloured blue .but does anyone know the part numbers for them especially no 6 as i hae a spare no 10
the reason i need no 6 is that the Nanacom is not reading the right temperature as the water temp is much higher than 60 which is what the Nanocom reads.
i am having fueling problems but i have ruled out no 10 sensor as i have replaced it also no 4 injector cranshaft sensor as i have replaced all with a known good ones. I have one more to replace and thats the timing sensor when i get one . I have alsooverhauled the FIP and made sure the timing slide is not sticking .
i need the temperature reading on the NANOCM to know when i do the timing with Datatech method
