Nissan 22680-7S000 Mass Air Flow Sensor

You can Select Your Vehicle to check if 22680-7S000 fits your vehicle.

The Mass Airflow (MAF) sensor is located on the throttle body for four-cylinder models and in the air intake duct for V6 models, and it measures the molecular mass of incoming air by use of a hot-wire sensing element. This sensor detects air that passes over this wire, which then cools and changes into a voltage that is relayed to the Powertrain Control Module (PCM). The PCM uses this information to calculate the required fuel injector pulse width for producing a desired air/fuel ratio. Problems like surging, stalling, rough idling etc may be caused by MAF failure and it could lead to certain trouble codes being set in EEC system. Before checking MAF sensor operation, check power and ground circuits. Plug out MAF sensor electrical connector. With ignition turned ON (engine not running), connect positive voltmeter lead to B+ wire terminal of harness connector while connecting negative lead to suitable engine ground point. If not, assess EGGS relay and related circuits. Also recommended is checking the ground circuit for continuity between connector and PCM. On 3.5L V6 models, with ignition ON and using positive voltmeter lead connected to reference wire terminal and negative lead connected to suitable engine ground point should produce around 5.0 volts-if there is no reference voltage present then suspect possible wiring harness fault or need PCM diagnosis. Reconnect electrical connector to MAF sensor; backprobe MAF sensor signal wire terminal with suitable probe while connecting positive voltmeter lead to probe and negative lead to suitable engine ground point; with ignition key ON voltmeter should read less than 1.0 volt (for 2002-2003 3.5L models approximately 1 volt). When starting an engine at idle, expect a range from about 1.0 upwards of 1.8 volts, which will increase as engine rpm goes higher from 1.6 to 3.0 volts. Unfortunately, simulating driving conditions in your driveway is impossible; however, one must see the voltmeter's needle rising as the engine speed goes up and if this does not happen you need to either replace or check on other parts of the MAF sensor system such as wiring harness integrity. In case they are okay, it would be advisable to consult dealer's service department or any qualified repairer for a possible PCM diagnosis. Noteworthy is that even with normal voltage readings, some signal faults may not show up when using a voltmeter; nevertheless, a dealer service department or qualified repairer should perform a sensor test and these problems are undetectable with voltmeter yet still give rise to driveability issues. With four-cylinder models, the air filter housing has to be removed followed by unplugging the MAF sensor electrical connector then removing retaining screws that secure the MAF sensor to the throttle body allowing for replacement of sensor. Contrarily, for V6 models note that plastic MAF sensor body and air duct are an integrated assembly which cannot be taken apart as separating them will be impossible without damaging any of the components therefore never try to do this as it will destroy either part. Unplug electrical connector from MAF sensor; remove clamp securing sensor to intake air duct and extract four fasteners that hold sensor onto air filter housing so as to allow new unit installation and connection process flow smoothly.

For 2013 and former/2014 and after models the Rogue Select apply a (MAF) sensor. However, for newer ones (2014 onwards), except the Rouge select models have a MAFIIAT sensor mounted on the air filter housing, near the air duct leading to throttle body. This Mass Air Flow/Intake Air Temperature (MAF/IAT) sensor is situated In the air filter housing and it is secured by two screws. Remove the electrical connector from the MAF/IAT sensor. Then, unscrew and remove this item from its position in the air filter casing. Conversely, set up as instructed above.

The MAF/IAT sensor is mounted on the air duct between the air filter housing and throttle body. The Mass Air Flow/Intake Air Temperature sensor is located in the air filter housing a nd it's held by two screws. To take it out, the electrical connector from this sensor should first be disconnected. Proceed to remove the screws and release the sensor from its position within the air filter housing. Installation merely reverses removal.

The air filter box houses the Sensor MAF /IAT. On this vehicle, the Mass Air Flow (MAF)/Intake Air Temperature (IAT) sensor is situated at the air filter housing and fastened with two screws. To uninstall it start by detaching the electrical connector from the MAF/IAT sensor. Then, remove these screws and in conclusion pull out all of the sensors from that air filter housing. To reinstall this sensor perform these steps but in reverse.

The MAF/IAT sensor is fastened on the air filter box. Disconnect the electrical connector from the MAF/IAT sensor. Remove screws and take out the sensor from the air filter housing. The installation procedure is just like removing process but in reverse order.

To replace the Mass Air Flow (MAF)/intake Air Temperature (IAT) sensor, you can disconnect the electrical connector. Also, remove the MAF/IAT sensor fasteners and detach the sensor from the vehicle's air filter housing. The Installation method is the reverse of the removal.

After disconnecting the electrical connector, remove the screws and take the sensor out of the air filter housing.

The MAF/IAT sensor fasteners should be removed.

Yes, either sensor can be removed without removing the air filter housing cover.

A defective MAF sensor can cause driveability issues such as surging, stalling, and rough idle.
