SOURCE: CODE PO102 after Mass Air Flow Sensor replaced

Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

SOURCE: 95 nissan maxima 3.0. have replaced knock sensor

I would have the charging system checked for over-voltage and AC ripple. There maybe a hidden wire harness problem if the charging system is okay. Wiggle test the wire harness while the engine is running to help locate the problem area. That is way to many parts replaced.

SOURCE: can the mass air fow sensor cause hesitation when accelarating?

Yes it could be bad sometimes cleaning it works and sometimes it doesn't. You should wait for the light to come back on and get the code before you buy a MAF sensor as it is expensive. You need to replace your air filter because that is likely that the fibers came off of it. You need to use a high quality stock replacement air filter.

SOURCE: 96 Nissan Maxima continues to have engine light

I had a similar problem - took it into 'Nissan Professionals' and they changed everything you did as well, and had no luck. After 4 or 5 times working on it, they told me that it was a 'loose wire' that had to be re-soddered and then the problem was fixed. I don't know where the wire was, but they made it sound like it was in or around the fuse panel under the hood.
I hope this might shed some light on the problem.

How do I reair this code


1122 is either the throttle position sensor or the mass air flow sensor. One of them is bad and will need replaced. I would lean more to the mass air flow sensor.
1126 will probably go off when you fix 1122.

idle control valve will need cleaning, also the mass air flow as well ( mas air flow cleaner only recommended) and the air temp sensor. may need cleaning or replacing, it could also be the spark plugs or leads. it could also need the egr cleaning as well, and sometimes it can be from were you get your fuel. if the garage you get your fuel from when its rain and you fill up and then have problems there could be water in the fuel as some garages don't know that ground water is getting into the tanks under ground.

There are a few components that could cause your problem. Your Idle air control valve could be faulty,or your mass air flow sensor could be damaged or just loose.

HOW TO INSTALL MASS AIR FLOW SENSOR


The Sentra is known to blow mass airflow sensors. If you bought an aftermarket sensor and it says to reprogram the computer you are pretty much out of luck. If it were me I would read the instructions again as it probably means that you have to disconnect the battery for five minutes and let the computer learn the new mass airflow sensor.

The mass airflow sensor, or MAF sensor, measures the amount of air flowing into the engine through the air intake. The sensor on your Nissan Sentra is located in the air intake tubing that runs from the filter to the fuel injection system. If your Sentra is idling rough, has problems starting and frequently stalls during normal driving, it is likely that the MAF sensor is failing and needs to be replaced.

jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Moderate

Things You'll Need:
  • Socket wrench and socket set Screwdrivers (Philips and slotted) New MAF sensor
Instructions
  1. Open the hood and locate the air box. It should be on the passenger side of the engine bay near the front of the vehicle. It will be a plastic, box-shaped object with a large plastic pipe running to the back of the engine.
  2. Examine the new MAF sensor. You'll be looking for this component in the air box.
  3. Remove the air box cover and pull the air filter out.
  4. Loosen the band clamps on the intake tubing with a screwdriver and pull the intake tubing off of the air box.
  5. Unplug the electrical connection to the MAF sensor and pull the MAF sensor out of the air tube assembly.
  6. Install the new mass airflow sensor and put the air box assembly back together. Installation is the reverse of removal.

Hope this help to solve your problem (remember comment and rated this).

try unplugging the mass air flow sensor. it's between the air filter and the engine throttle chamber. it has an electrical connector. if it idles fine, you need a new MAF sensor.

Poor idle, power loss off idle then takes off if you give it more throttle like a quarter more pedal, engine code says bank 2 is to lean


You need a new MAF (mass air flow sensor or air flow meter as its called). and you will also need a new air filter, since you most likely used aftermarket one and that's what killed that MAF sensor/meter. Aftermarket air filters dont sit right in the box and are not oil soaked, which helps to catch any debris and dirt coming into your engine. Replace you air filter with Nissan filter and install a new MAF/air flow meter. If your air box is dirty, clean that out too. MAF sensor will run you about $500 and the air filter about $17. Common problem on a Sentra if you are not using Nissan air filter.
