Coolant Temp Sensors

Recommended Posts

In the pic there are (I believe) two coolant temp sensors. Can someone please advise which one feeds the ECU and which one feeds the dash temp gauge?

 

My temp gauge is acting up. It takes a loooong time to reach normal temp on startup. I thought that this may have been a dodgy thermostat but the gauge sometimes drops to zero for no apparent reason, no consistency to it. I'm hoping that it's a sensor problem as I don't fancy replacing the thermostat on this engine.

 

I'm also hoping that this will help with my appalling cold idle!

 

It's a 2JZ-GTE block BTW.
