📄️ ETB Throttle Position
Electronic Throttle Bodies typically have a primary and secondary throttle position sensor. This is to ensure safe operation of the vehicle. When connecting an ETB to a FOME ECU it is always required to have two redundant signals (e.g. primary 0-5v and secondary 5-0v).
📄️ Mass Air Flow Meter
A MAF (Mass Air Flow) sensor measures how much air is entering the engine. The engine computer (ECU) uses this information to calculate how much fuel to inject so the air-fuel mixture stays correct. Most MAFs work by sensing how much incoming air cools a heated element, which tells the ECU the mass of the air, not just its volume. The MAF sends a voltage back to the ECU (the raw MAF) which is then converted to an actual MAF value in Kg/h units using a calibration curve.
📄️ Throttle Position Sensor
Throttle Position Sensors are used to tell the FOME ECU the angle of the throttle blade. Most sensors are 3 wire:
