How can you tell if an idle air control valve is working?
Disconnect the IAC connector for a couple seconds while your engine is idling. If your engine idle didn’t change, you can suspect it to be the IAC. If it is working properly, unplugging it would cause your idle to freak out. Also check the wires going to the IAC connector.
Why is my air flow sensor not working?
It is possible that there is a problem with a BARO (barometric pressure) sensor that is reading faulty. Its purpose is to measure atmospheric pressure, the amount of air entering the engine, and supply the ECM with a calculated reading that allows the engine to make corrections accordingly.
Where is the fresh air sensor on a Nissan?
Park your Nissan vehicle in a safe place, with enough room for you to work around the front of the car. Open the hood. Locate the MAF sensor electrical connector. The sensor is mounted in the fresh air intake duct–close to the throttle body, fuel-injection system or air-filter housing, depending on your Nissan model.
