The sensor is mounted on the suction manifold. The resistance of the sensor must correspond to that shown on the graph (photo). To remove the sensor, disconnect the battery from the ground, disconnect the connector and unscrew the 2 screws. On some cars, the sensor turns out of the manifold. When installing, wrap the threaded part of the sensor with Teflon tape.
