A throttle position sensor (TPS) is a device that transmits the throttle opening angles data to the ECU that controls the fuel consumption on the basis of the throttle angle information.
When a throttle valve is completely closed, it is at 0 degrees.
That is, whether the valve opens or closes, the TPS expresses the angles numerically.
The throttle opening angle at 0 degrees is calculated in the two following conditions: 1.
vehicle in idling state 2. vehicle in engine braking mode.
However, the fuel consuming circumstances of the two are far different.
When an engine is idling, the car consumes gas. As you use engine braking, conversely, the car does not need fuel to run.
Even if the throttle valve is closed, the different car situations bring the different fuel control strategies of the ECU into operation.
Furthermore, the TPS helps the engine ignition timing and the fuel emission control to be the most suitable by transmitting the in-depth data on the throttle position angles.
Actually, the genuine TPS for NA6CE B6 can only recognize whether the valve opening angle is 100 degrees maximum or 0 degrees.
The air flow meter of the same model, in addition, tends to provide enough air resistance to be replaced as upgrading cars, even though the device plays an important role in the engine system by measuring the amount of air entering the engine.
It means the difficulty to remove the air flow sensor from your car.
Freedom ECU developed by E&E System in Japan provides you with the freedom from the air flow meter because the ECU estimates the amount of air consumption by measuring the air sucking force of the engine through the vacuum sensor.
Freedom ECU is also suitable for fly-by-wire throttle system.
It means that the TPS sending information to the ECU is acquired to calculate precisely the throttle opening angles.
