My Max threw a code today P0101. And the definitions are
Sensor Circuit Range/Performance error
Probable cause
1. Open or short circuit condition <- WTF
2. Poor electrical connection <- WTF
3. Faulty IAT Sensor <- WTF
4. Faulty EVAP control system pressure sensor <- WTF
5. Faulty MAF Sensor <- Maybe??? Got a Stillen SRI still WTF
Any suggestions? I'm going to install back my OEM intake first if the light is still there.... off to the communist Nissan stealership.

 

I'm having the same problem, only thing is I have stock everything.

 

Wow stock and throwing the same code as me? Better bring it back to the dealer man. That's weird.

 

I'm doing that this weekend. Need to find out why, it did that. During the weekend, I opened up the filter to see if it needs changing, plus, before I did all that, I had some sort of air module changed. (Don't know exactly which one). So, I have to figure it out myself before I do anything. Anyway, I have a full warranty, why not abuse it.

 

Check for any vacuum lines that might have come off. This will throw a P0101 code. My daughters Toyota had the same problem this last weekend and I found a loose vacuum hose that came off the airbox, reconnected it and disconnected the battery for 15 minutes to reset the computer and the check engine light went away and never came back after a days worth of driving.

 

Interesting. I'll have to check. The only lines I took off was the stock intake rubber hoses and MAF sensor. I checked everything and everything was tight and secure. I placed back my stock intake so we'll see in the long run. If my car throws a CEL again, I think it might be the MAF sensor or another sensor. If it's another sensor, then at least I know my stillen intake isn't the problem.
