    ECU Coolant Temp Sensor N/A Same as TT? Removal Help

    Hi All

    Am doing a few bits on my friends supra and it needs a new ECU Coolant Temp Sensor. I found this on eBay but cannot find a Non turbo equivalent, are they the same? Is there anywhere else i can get one if they are not? Don't mind a second hand one for diagnostic purposes.

    eBay Sensor:

    Also any one with any tips for removing and fitting the new one as if i'm correct it is the sensor screwed into the block under the power steering assembly is it not? Tried the workshop manual but couldn't see it in there!

    I'm an MR2 person myself so supra's are a new project for me any help or tips appreciated.

    no mate it doesnt plug there,

    it goes into the radiator


    easy to do, need to get at it from underneath, its at the bottom of the rad by the drain plug. simple open end spanner on it will do


    i too have just ordered one from toyota, 45+ vat. im not sure if the NA and TT are the same.

    I thought the one in the radiator was the Temp sensor for the dash gauge? Or at least i'm reading the workshop manual wrong (quite possible btw!)

    Ah I did wonder if it was you! Saw it parked up on the drive the other day when I passed through haylands way. Haven't seen it on the road in ages.

    I thought the water temp sensor was screwed into the top water neck?

    I will check and get back to you a little later, but am 99% sure that the sensor in the bottom of the rad is for the OEM supplementry electric fan in front of the rad on TTs. It has normally closed contacts and operates a relay in front of the passenger headlamp and that in turn switches the fan motor in. It has no bearing on the temp feedback to the ECU if I am correct. Someone on here will know this for sure and I will go out later and check anyhow. As previously mentioned, the engine coolant sensor for the ECU will be in or around the head somewhere.

    Could this be the problem with your starting Lude, looking at the wrong sensor?
