The sensor itself is on the top of the engine, (under the intake) but are you sure that the sensor is bad?

Does the engine reach operating temperature after running for a while?

Customer: replied 11 months ago.
It does reach temp according to the gauge, the fan runs as well. The engine will get hot if left running without moving. Temp goes down to middle range in temp gauge will driving around.

I see, thanks. There are some tests that can be done on it to diagnose the codes. Normally the tests are done with a scan tool.
