2011 WRX CEL after fixing blinker

scx89 · 12-29-2012, 01:10 AM

I just took off my intake so I can reach into the blinker bulb to fix it. It had a fast blinking problem and the dealership just couldnt fix it lol. Turns out it was a loose bulb...

Anyways, during the intake uninstallation i saw that there was a lot of bees and random crap in my filter, so I just tapped it on the floor to get anything heavy out of the filter. Then I put everything back together and when I turn on the car afterwards I get a CEL with the codes reading
P0102 - MAF sensor low circuit
P0113 - intake air temp circuit high input

I'm hoping those just came up because I slightly cleaned up the filter or it was because of moving the MAF sensor a bit. I didn't disconnect the battery while doing this - am I supposed to?

Is there anything I should be watching out for?

reset the connection to maf sensor.

Clean your MAF sensor if the above doesn't work. You can pick up a can of maf cleaner for pretty cheap at auto stores.

Make sure everything went back together properly and you tightened up the connection after the MAF and that your MAF was plugged back in.

Also make sure you didn't put the maf on backwards

MAF doesn't fit in the stock filter housing backwards, screws won't line up.

It sounds like its not plugged in or not plugged in all the way. If not, check the wires going into the maf connector if the look pulled out that's your problem. The maf sensor has the intake air temp sensor built into it. So if the connector is no priestly seated both codes will come on.

I, too, would just re-check the maf connections and assure it is seated properly. I'm doubtful your maf needs cleaning already on a 2011, but it's possible. Please report back.

Thanks everyone, i replugged the connection and it has been perfectly fine.

That's as easy of a fix as they come!
