What is the sensor called, that is screwed in the lower intake. Right next to the thermostat housing. I tried to tighten it because it was leaking coolant. And the connector broke that plugs into the harness. It's not the ect neither.

 

Im not sure but it sounds like it could be your water temp sensor

 

But wouldn't that be the same as the engine coolant temperature sensor? I just need to replace it ASAP! Because I can't drive the car without it replaced.

 

can you post any pics? it would help figure out which sensor it is.

 

also what is the year and model of your car

 

1993 sc400. My buddy said that my car has two coolant sensors. One for the gauge, and one for the computer. I'm guessing the one that I changed with the green head, is the one for the computer.

Number 2 is the sensor. But what is it called? I'm at the parts place trying to get the part name or number.

Part # 89422-20010 Sensor

 

The part number is 89462. I went to Lexus, and they told me it is cold start injector sensor. There price.... $221.00

I never said I bought the part. I only went there to find out what the sensor was called, and to get the correct part number. I found a guy who has them brand new for $27.00....lol! There was no way I was paying $221.00 for a sensor. My mother didn't raise no fool.
