Typical Fuel Tank Pressure Sensor Circuit Diagram

The following schematic shows the Typical Fuel Tank Pressure Sensor Circuit Diagram. The fuel tank pressure sensor signal voltage to the VCM varies from a minimum of about 0.1 volts with pressure in the fuel tank to above 4.0 volts with a high vacuum in the fuel tank.

Typical Throttle Position Sensor Circuit Diagram

Here is a typical schematic diagram of the car Throttle Position Sensor Circuit. The Throttle Position Sensor (TPS) is designed to indicates the position of the throttle valve. How the Throttle Position Sensor works?

Mass Air Flow MAF Sensor Circuit Diagram

The following schematic shows a typical circuit diagram of the Mass Air Flow (MAF) Sensor system. The mass air flow sensors converts the amount of air drawn into the engine into a voltage signal. The primary components of the MAF sensor are thermistor, a platinum hot wire, and an electronic control circuit. The thermistor measures the temperature of the incoming air.

Exhaust Gas Recirculation (EGR) Temperature Sensor Circuit Schematic

An EGR (Exhaust Gas Recirculation) temperature sensor is an electrical sensing probe that is installed in the EGR passage between the EGR valve and the intake manifold. It is connected to the THG terminal on the ECM (engine control module). When the EGR valve opens, temperature increases. The following schematic shows a typical circuit diagram of the Exhaust Gas Recirculation (EGR) Temperature Sensor.
