This denotes an issue with the Exhaust Gas Recirculation system, which transfers exhaust gases from the exhaust manifold to the intake manifold in order to lower combustion temperature. The fault code will appear if the flow of gases is lower or greater than normal.

how do you clean mass air flow sensor on a 1998 Nissan altima? To clean the mass air flow sensor , you need to get a can of CRC mass air flow cleaener frm auto zone, Kragen, Pepboys, Sensor is attached to the tube (next to airfilter). again you need to use mass air flow cleaner ( CRC ). I use this on my ford windstar and Nissan sentra 05 and 95. it runs better after cleaning the mass air flow sensor.
Back in 2006, my Sentra with 78K miles was stalling and was cutting out while accelerating. The Nissan dealer found that the air flow sensor was failing. The part was about $200 with $270 labor. Please note that there are also several recall campaigns and one is on the crankcase position sensor which can go out and stall your car for good. Good Luck!
it will be on ur air intake hose and it will have a wiring harness plugged into it
You need to replace air flow meter for your Sentra. Make sure the air filter is clean! an engine needs air to burn the fuel!
