Coolant temperature sensor location

I'm not familiar with your engine, but why are you looking for the sensor? Replacing the sensor won't solve the unacceptable condition it's reporting.

Coolant temperature sensors are usually close to or on the thermostat housing, and those are usually at the end of the upper radiator hose. As Heyman1104 said, the thermostat is the logical suspect. When it sticks open, the coolant doesn't stay in the engine long enough to get hot.

Dude, the code isn't telling you that the sensor is bad. It's telling you that the coolant is staying too cold. This happens when it either flows too freely (thermostat stuck open) or if the cooling fan is running at full speed constantly. Change the thermostat.

Here's the information that ALLData has on it, pictures and all. This is for the sensor that reports the temperature to the PCM, which is the one that you're needing. Hope it clarifies things for you.
