Throttle position sensor Throttle position sensor, is also known as the throttle opening sensor. It is used to detect different working conditions of the engine to feed the signal back to the controller, so that the controller can correct the fuel injection amount or perform oil cut-off control.
Transmission gear sensor Transmission gear sensor is generally equipped with automatic vehicles to detect gear signals. There are multiple contacts on the gear sensor. When the car shifts gears, the contact will move the relative gear, the voltage will be changed, gear sensor will detect the shift signals to transmit it to the transmission controller and control corresponding executive component.
EGR valve position sensor EGR (Exhaust Gas Re-circulation System) is a system that introduces part of the exhaust gas into the intake manifold and returns to the cylinder for re-circulation to participate in combustion during the engine operation, and the role is to reduce the emissions of NOx . EGR valve position sensor provides closed-loop modified feedback control of the actual amount of exhaust gas re-circulation.
