Where on a 2.0TS 16v engine do I find the water temp gauge sensor??

That's what I thought, the one on the thermostat housing, but a bosch specialist said that there should be one with a single wire linked to the gauge.

Get the engine up to temp, then disconnect the wire and see if the guage falls, :D
Thats the problem, I'm not getting a reading on the gauge.

Do you have two wires going form the thermostat or that area? I disconnected one on the twinny and the guage dropped....I was confirmeing which one was the water temp guage at the time.

Barry with the use of a bit of wire :D short the wires on the sensor to ground one at a time with the ignition on and get Mrs Barry to watch the gauge.....................It should start to rise as you do this (the gauge that is :p :p ) as you are creating a high resistance

If this sensor is not working, does this mean the ECU is not sending out the correct signals to the fuel injection side?

It will be running as though you`d just started it up even when the engine is upto temp ie over richening the fuel ;) :D

So YES :D

Barry I've had a look at the manual and the gauge works on the same sensor as the warning lamp and not the one for the ECU as I had assumed :eek: :eek: it's just behind the thermostat on the head and is part number 7762300 priced at about £23 from Alfa :rolleyes: :rolleyes: I also did a search on the part number and it fits a few Fiats & Lancias so you should be able to get one from a motor factors :p

Thanks David, I've just driven into work and disconnected the sensor on the thermostat and the gauge didn't drop, so I'd assumed that it wasn't that one.

ps The gauge reading is intermittant.
