Replaced worn out throttle body as authorized.
I noticed a spark plug wire had been arcing (spark) against the fuel line. There are a lot of misfires stored in the computer memory. Most are for #3 cylinder which is the one with the spark jumping from the wire. Worn spark plugs cause the spark to go where it shouldn't and I pulled the #3 plug. I have to think that is original plug. I have never seen a spark plug with that much wear that was still running. The plug wire was broken at the plug end and came completely apart when accessing the plug. So... this needs spark plugs, spark plug wires and ignition coil as well. I've taken the pictures relevant. 

Sensor Types: Thermistor

A thermistor is a resistor that changes value according to temperature. They are often used as temperature sensors. We'll use the coolant temperature sensor from a '98 Chevy truck for an example of a thermistor type sensor. This sensor is for the temperature gauge operation. Room temperature is about 80F and we have a chart of rough resistances at various temperatures.

The resistance of the sensor falls within range.

 We should see a change if we heat it up to around 100F.

Or cool it down to around 30F.

So that is how a thermistor type sensor works!
