It is located close to the radiator outlet housing right next to the coolant temp sensor, it will only have 1 wire going to it and the connector could be black or a dark gray color, once the connector is unhooked a socket and ratchet is all you need to replace it, just make sure the engine is cold and you replace the coolant you loose during this operation. As you had to ask where the sender is I am assuming that you haven't done the ohms check on the gauge itself so your hoping that a sender will fix the problem.

Didn't know if you meant engine temp, inside heater temp reading or outside temp reading. Also, how do you know it is inaccurate? Talking engine temp, you may just have a bad thermostat or sending unit. Also, it is possible the gauge is reading correctly and you have a radiator, hoses or some other problem

Sorry should have been more specific. It's the outside temp and it's pretty obvious not matching outside temps. Thanks SamR1

Those can be really crazy sometimes, you have to drive at least 35 MPH for 5 minutes for them to display correctly, if that is what is happening it is normal but if it doesn't come close then the sensor could be the problem, it is located behind the bumper on the battery side attached to the rail.
