hey there everyone, I am having a problem nom its been persisting for months now. Everytime i turn on the engine and turn it off, i hear a weird sound, it sound like a small alarm. I checked OBD II, i've changed my MAF sensor and the problem still is on. Does a Rear Oxygen Sensor problem, may cause the car to produce a sound such has an alarm.

^^^That's your throttle body opening and closing. It's normal.
