Trying to locate engine coolant temperature sensor on my SUV?

You've got a cylinder head temperature sensor under the intake, and may or may not have a coolant temperature sensor on the intake. The cylinder head temperature sensor is generally the sensor that the power-train control module looks at, but on some applications it could be the one and only sensor, the PCM could network the information to the instrument cluster. Here are two pics of these sensors. To remove the cylinder head temperature sensor the intake will have to be removed.
