It would be a very rare case for both of those sensors to be bad at the same time. I would have a certified repair shop to determine the exact cause before you buy parts you do not need.
The air charge temperature sensor is located in the air inlet between the air filter and the air horn. The coolant temperatur sensor is located in the intake manifold. I believe that you need to have a Repair Shop scan the engine and do diagnostics on the car before you replace parts that may not be bad. Just because you get a code does not mean that part is bad.
Which temperature sensor? There is an air-fuel charge sensor, and a coolant temp sensor.
That would depend on which temeprature sensor you are asking about. Is it the coolant temperature sensor or the air charge tenerature sensor you are asking about?
I'm a single woman and i need to change the air charge temperature sensor on my 1993 olds cutlass supreme. i need a "how to" please.
The coolant temp sensor would be located between #3 & #5 spark plugs. The air charge temp sensor would be located in the air intake snorkel between the air filter box and the throttle body.

I believe it is on the front of the intake manifold and it should be the second largest one. I believe the largest is the air charge temp sensor
Yes
There is obviously a leak somewhere
Not "change", but "charge". Conservation of charge means that the total charge in a closed system can't change.
The resistance of a thermistor changes when its temperature changes due to the inherent properties of the thermistor material. In a negative temperature coefficient (NTC) thermistor, the resistance decreases as the temperature increases, whereas in a positive temperature coefficient (PTC) thermistor, the resistance increases as the temperature rises. This change in resistance is caused by the variation in the number of charge carriers (electrons or holes) and their mobility within the material as temperature changes.
If you are talking automotive, then it's Air Charge Temperature.
