I've got a CHT Sensor that I believe is for a 1973 2.0L engine. The only markings on it are 3 numbers on the side, which I think read "543".

I can't match those numbers against any of Brad Anders' D-Jet pages.

I measured the resistance of it. Using the 2K scale, it reads 1.2xx, which I think means it is measuring at 1,200 ohms.

Can anyone help me figure out what CHT Sensor this is?
