IM supercharger 9.5 pulley and upgraded bpv. Im throwing these codes, anyone have any insight?

P0102<- Mass of Volume air flow circuit low inpu
p0113<- Intake Air temperature circuit high input
p0172<- System too rich (bank 1)
p0420 <- Catalyst effic below threshold

Would my MAF possibly failing cause this?

Mr_Meaty

I had the p0113 code because my primary sensor was not plugged in.
Try unplugging it (from the connector, not the header) and plugging it back in. Clear the codes, and then start her up.
If your MAF was failing, I dont' think your car would start.

Its weird how it only comes on after driving for a little bit, its usually when Im not beating on it.

Mr_Meaty

Hmmm...
When I was getting the p0113 code, it would come on after about 30sec.
My "Primary bank to rich" code would come on after about 2 days when not in boost cause my tune is to rich when not in boost.

Considering the MAF and IAT are built into the same unit and both are causing codes, that would lead me to believe the issue is in your MAF. This could also cause your rich reading and in turn your catalyst code. Start with the MAF, its connections, its mounting and seal, etc. Make sure everything there is perfect before going forward. I would focus on getting rid of the MAF code first and see if any other codes are left.

Would spraing any of that MAF cleaning stuff do anygood do you think? It seems the CELs only come on when not in boost, when Im just driving normally go figure.

ive seen MAFs go bad that didnt affect the drivability of the car. like engifneer said your MAF probably went bad and is causing the other codes. bring it to the dealer and try to get it warrentied

Cant I have 66k on the ODO

ouch.. if you have any friends with a tc ask them if you can borrow their MAF and drive around for a little bit before you invest in a new sensor.

I was driving it tonight and it didnt come back on after resetting the ecu, but it just hasnt learned to idle itself yet and is sitting at like 500 rpm which is uber annoying.

Mr_Meaty

MIne sit's at about 500 and I LOVE IT! Cause before my tune, when it would sit at 800, my speed source motor mounts would shake the $hit out of my interior!

whenever mine hoovers around 500, thats when it gets shaky. when at 800 its all normal. stock mounts though lol. but to the OP, as many have already said, get the MAF checked out. it would be a good idea to borrow someone's MAF before buying one because those things are pricey. but then again it would suck to mess up a friend's sensor and have to buy them a new one as well.
