code P0101 2012 rogue

[speedydog5]

i changed mass air flow twice after i had p0101 code keeps coming up i was told computer needs a reflash by indy mechaninc brought to dealer said they reset computer for $150 if it comes on again i need throttle body cleaning and a relearn that can only be done by dealer i looked up re lean on google lots of ignition on off procedure but for older models now i dont know if i got shafted by dealer and he just cleared code or not i just erased code after it was at dealer so my question is after i pull off throttle body to clean can i do a re learn procedure myself or does it have to be done at dealer

I changed the mass airflow sensor also. Code still returned. It eventually goes off by itself, so now I just ignore it. If that bothers you, go to advance auto parts for $25 and get a scanner. You can read the code yourself and, if MAF, clear it yourself. If its something else, you still have the option to take it in for service or diagnose it yourself first.

You could also have an intake leak (vacuum leak).

Not sure if your talking to me or the OP. IF me, I would suspect a vacuum leak would be continuous, not intermittent. No? Otherwise the code would not "turn itself off"

Both of you. The code P0101 also lists intake air leak as a possible cause.

P0101
- Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection
