The main issue is body composition (see the body fat calculator for more). Calorie expenditure will vary depending on the ratio of body fat to muscle or lean mass. NOTE that as our bodies adapt to exercise and our body composition changes - so will the amount of Calories burned.
The definition of a throttle is a valve that controls the fluid flow. An example of a throttle is a car part that controls how fuel moves through the system. Throttle is defined as to control the speed of an engine or the flow of fuel in an engine, or to hold down or choke.
Throttle Position Sensor (TPS) The electrical circuitry to both the AAP and TPS sensors is the same. Just like the AAP sensor, the TPS sensor unit is mounted on the throttle body, converts the throttle body butterfly valve angle position into a voltage signal, which is transferred to the PCM unit. The main purpose of the TPS is to monitor the position of the throttle plate in the combustion engine.
