P0128 Different issue

[AlanP]

Hey all. I've been searching around but can't find the same issue P0128 I'm having:

When the weather cools I start throwing a P0128 code. It happens when I first start the car, not after 10 minutes of running. Car runs fine the entire time. I have a 180T non-drilled and have replaced it with another 180T non-drilled, reset the code, and it still comes back on. Suggestions?

Temp sensor gunked up?

put the 195 back in?

have you changed the temp sensor or checked the wires leading to it? its got a short harness too, so 2 plugs to check and clean.

Where would I locate the sensor?

 

[Scottydoggs]

its under the t stat. in the bottom of the lim.

Never heard of that. Wouldn't it be in the radiator?

 

[Scottydoggs]

theres one in the rad too, but its the low coolant sensor.

look under the lim under the t stat, its there.

I see it. Can I pull it out without draining the fluid??
