What does TPS do?
The TPS picks that information and relays it to the car’s engine control unit (ECU). The ECU uses the information to determine how much fuel to inject. As mentioned already, if the throttle position sensor is working properly, the engine will inject the optimum amount of fuel for the idea fuel/air mixture. If the TPS malfunctions, the ECU won’t ...
How does a TPS work?
It picks up air from the intake, passes it through the mass airflow sensor and into the throttle body. While there, the TPS will continually measure the amount of air. The engine then uses that data, alongside other values like RPM, air temp., and mass air flow in determining how much fuel to inject.
