2002 sentra se-r with 5 spd. I am almost finished changing my engine from my oil consumption problem and came across a problem. looking from under neath my car below from under the engine & the intake manifold there is a black canister with a bracket that mounts to the intake. on the bracket there is a sensor that is brown and the wire connector(Brown color) that comes off that has another wiring harness connector(gray color 2 wire) that I cant seem to find the sensor that the connector goes too. Does anyone know or can anybody check there car and see if they see the wiring harness I am talking about and tell me where the sensor is. I would really appreciate it.
