Title: ECU coolant temperature sensor?
Post by: MrDJ on 18 August 2010, 18:48:29
Where abouts do I find this on a X20XEV and is it a simple unscrew and replace job or is there more to it?

Cheers

Situated at the rear of the engine block just below the cam cover. I believe the ecu sender is the one with the black oval plug? HTH :y

That is the location but not sure why the one in your pic is black Phil?

It is simply unscrew and replace, you'll lose a little coolant I think, but it's pretty high up so not too much.
Access isn't peachy with EGR and DIS/leads in the way.  If you take the leads off the DIS it will be better, but make sure you label/note the correct positions of each if you do.

I take it you're certain that it has a fault?

Mine is the 2.2 z22xe, so it's probably a different sensor head? Sorry if i've given a false 'positive' :-[

Ah, that makes sense, sender may well be different on 2.2.

Could be worth asking Jimbob or another 'God' to substitute your pic of these bits into the 'Underbonnet 2.2 labelled photos' Maintenance Guide thread in place of mine.  Having seen how different the 2.2 'chunk' looks it might be confusing for peeps to see the 2.0 one of my pic?

Cheers. Changing it as local mechanic reckons might be why my fuel consumption is high.
