The sensor is mounted on the intake manifold. The resistance of the sensor should correspond to the one shown in 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 is unscrewed from the manifold. When installing, wrap the threaded part of the sensor with Teflon tape.
