Temp gauge reads high all the time
#1
Berlingo 2.0 hdi van on an 02 plate, temp gauge stays on high, stop light on. Engine fan continually running, Checked not overheating and full coolant, replaced temp sensor in engine compartment, still not fixed.... Any ideas please

Hi, the temp sensor (should be green with two wires) goes straight back to the engine ecu on the 48pin brown plug.
Do a shutdown procedure and disconnect the battery.
have a look at these connections and make sure they are clean / no corrosion.
Don't forget to do a correct start up procedure.

What happens if you leave the sensor disconnected? Confusedcratch:
Do you still get the same fault?

Hi, thanks for the reply, if I leave the sensor disconnected, same fault. Sensor has been replaced with a new one. I took off the 48 pin plug and gave it a spray with wd40, it looks clean. Unsure of shutdown procedure, then followed your link Smile I will try that tomorrow (Cornwall, it's heaving down with rain!) when I get to work and a shelter. Smile
