Hey guys,

I have a 2011 G37S Coupe with about 140k miles.

So recently I’ve been trying to get my car smogged, but have been having an issue getting my SES light to go away. I hooked it up to my OBDII scanner and got a P0106: Manifold Absolute Pressure code.

I attempted to just clean the sensor instead of dropping the $150 for a new one. Pulled it out, cleaned it out, hooked it up and reset the codes on the car. I drove it around for a couple weeks and the SES light never came back on so all seemed well.

Took it back to the Smog shop this weekend and they hooked it up to the scanner, they said everything was good and ready…. Except for the fact that the Permanent Code was still there so it wouldn’t pass. Between the time of me cleaning the sensor and taking it to the smog shop, I had driven it a minimum of 300 miles both freeway and city miles. So I would have assumed that the permanent code wouldn’t have been there but I suppose I was wrong.

Fast forward to today, I figure I’ll just drive the car around a bit more and try the shop again this weekend. Except the SES light came on this morning again with the same code.

So I guess my question is, what steps do I need to take? I’m going to go ahead and just buy the new sensor but I don’t want to waste my time again if I can’t get this damn permanent code to go away lol.

Any help would be appreciated, thank you guys.
