Thread: A list of sensors and how they work?

I think that is an excellent idea. If someone takes up the challenge then I'll sticky it, if not I'll see what I can dig up.

I kind of tried searching the web, but I am not very good at it and didn't find what I want. The reason I said GM tech is because they have access to all of the GM info.

I think if we all collaborate together we can make said list, I'll start:

Cam Sensor- Hall effect? -used for injector timing
Crank sensor- Hall effect - two parts, one used for timing, other used for Tach and Traction control
Intake air Temp-thermistor- Used to help fueling by telling pcm intake air temp
Mass Air flow - ??? - sends a Frequency that equates to mg/sec of air the engine is ingesting, used for fueling
Throttle Position Sensor- Potentiometer - used to tell the computer how open the throttle plate is and also the speed it moves can be measured, used for transmission shifting and fueling
Manifold Absolute Pressure(MAP) - used to run engine during maf failure, also used to aid in fueling and judging engine load
Coolant Temp. Sensor- Used to tell the temp of the engine through the coolant, assists in fueling(by telling when it is warm enough for closed loop operation)

There are many more, and if any of above are wrong/ need to be erdited please let me know
