Can anybody give me a diagram of where the coolant temp sensor is located? I was told in the head below the upper radiator hose but the one I found and replaced was in the air intake behind the driverside headlight.

First of all thank u so much for ur donation it really helps us answer everyones question.U replaced the inlet air temp sensor. The coolant temp sensor is screwed into the cyclinder engine below where the upper hose goes almost where the head meets the engine block on the right side of the head facing the engine. There are two wires going to it a yellow one and a black one. The sensor looks just like the one u change even has the same style connector. Don't forget to check and make sure the connector isn't corroded. Let me know how it goes.
