An exhaust gas recirculation valve sensor has a housing with a cavity. A shaft is located in the cavity and extends out of the cavity into contact with a portion of the EGR valve. A sensor mechanism is located in the cavity and generates an electrical signal proportional to the amount of force applied. A spring mechanism is located between the shaft and the sensor mechanism to translate movement of the shaft into a variable force on the sensor mechanism. The variable force on the sensor mechanism causes the electrical signal to change. The sensor mechanism includes a substrate and a strain gage resistor that is mounted on the substrate. The spring mechanism includes a sleeve attached to the shaft and a coil spring.
