I need to change my engine coolant temperature sensor because my check engine light is on and is throwing code P0117-ENGINE COOLANT TEMPERATURE SENSOR LOW, however I cannot seem to find it. Has anyone changed one before and knows where it is located, i'm pretty sure it's somewhere near the alternator?

What year truck and what engine? Details!
Rolling coal is like spending a considerable amount of money to reconfigure your plumbing system so that when you shat in the toilet, it gets sprayed all over your furniture because someone suggested you should use a better-performing furniture polish.
Its behind the alternator on the intake manifold down next to where the thermostat housing is (if looking at your engine from the front). But, depending on the year of your truck, you may have one or two.
-On some '98, some '97, and all '96 and older, there should two (one is a sensor, one is a sending unit). One is for the PCM (the ECT sensor) and the other one is for the temp gauge and warning light (a sending unit). The one to the left of the thermostat housing is for the sending unit, and the port just behind and to the right of the t-stat housing is for the ECT.
-On some '97, some '98 and all '99 and newer trucks, there is just one that does both jobs (sensor and sender) and it should be to the left of the t-stat housing.

The sensor the auto store gave me is two prong...... Do I just unscrew the sensor and slip new one in? There is enough under there I do not want to get the wrong advice and start unplugging anything I shouldn't.... Thanks for the help.
