Technical Multiecuscan showing -40 temp

[scott9951]

I'm trying to reset some things on my 1.2 using multiecuscan but everything is out of range.
Car runs fine but only thing on multiecuscan that's is wrong is running temp that shows -40.
The ect is ok as it's sending a message to ECU but had a read and wiring can corrode.
Can anyone tell me which pin in the ECU connector goes to ect so I can check for continuity?
Thanx for any help

Open circuit/failed ect so no signal to ecu will cause mes to show -40
So it could be ect sensor fault

Wouldn't that show up as a fault?

Also forgot outside temp is also -40

What does the temp( engine) guage read when driving?
The outside temp sensor is in the passenger mirror I believe

It's a pop so doesn't have one but multiecuscan says -40 for that as well
Engine temp when running is normal.
The car runs fine with no warning lights, I just can't do anything with multiecuscan because it's out of range

Mes is showing outside temp -40 because no outside temp sensor fitted.
Proves default value for open circuit is -40.

Read engine coolant temperature using mes when engine at normal running tempertaure and post on here.

Not guaranteed to flag a fault

What's the mpg like?

I don't know, it's a spare car I've just finished repairing

It was the sensor, changed it that problem solved, now got bigger problems. The joy of owning fiat
