I had my computer read the code for the check engine light and it was p0125.

By researching this it seem to be a coolant temperature sensor. Where is that located under the hood? I would like to install it myself.

Your engine coolant temperature sensor is located on the right side of the engine, pictured below.

I have Toyota Sienna 1998, I got code P0125. I tried to replace the coolant temperature sensor and thermostat, but the check engine still on. Anyone have any idea?

Thanks
