PCM 0101 popped up during cruising
 

So I am cruising at about 75 MPH and chilling there; Black Magic Woman blasting and suddenly CEL comes on. AP is handy so I pull the code while without missing a beat and it states PCM 0101 - something's up with the MAF sensor.

I scratch my head, reset the code on the fly and start monitoring the MAF sensor but all appears to be well. I cruised about 8 miles before getting home after the CEL reset and got nothing.

Could this be a fluke? A foreshadowing? Mods are in the sig and am on a DJ based e85/91 tune that so far has been nothing but fantastic :o

Any recent logs?

Go to autozone and spend 10 bucks on some MAF cleaner. It's worth a shot and could fix your problem.

Yeah - Dustin looked through them yesterday and they were fine. I just re-flashed today, drove about 60 miles since I flashed. I'll see if the code re-pops; I'll probably also clean the corksport filter - it has about 17K on it now :p almost a year worth of driving for me.

I cleaned and reoiled mine last weekend. It was pretty damn dirty at 11k miles.

Could've gotten the MAF a little wet...dirty MAF...etc..clean it and don't worry about it if it doesn't come back.

What would you use to clean the MAF sensor? Anything that can be bought at Kragen?

I would recommend MAF Cleaner.

Haha - how... quaint :lol:

Update:

So I finally got around to cleaning the MAF last Sunday. I can't say the MAF was uber filthy but it was, nevertheless, cleaner after I finished with it. I used the shit they sell at Kragen - don't think it should matter what I use though.

I didn't have much of a chance to clean the air filter though; I just took it off and patted it down but I bet I need to do a proper cleanup (filter has ~20K on it).

Right after I cleaned it, I took it for a spin and it seemed to be fine but, the three days later (Weds) the code still popped up. I figured it must've been a ghost code that just manifested itself and reset it... and it came back up again today about 40 miles after resetting it.

Now mind you - when it comes up - there is no hesitation, no hiccup, nothing. Car drives great, feels great, AFRs are good, no knock!

Could a tune be causing this...?

CorkSport seems to suggest that perhaps the MAF sensor is not sitting flat and could be leaking - but if I have it screwed in tight - shouldn't matter, right? Or - should I use a third party sealer around the MAF?

If you're that worried about the seal, get some of the "Right Stuff" from your local auto parts store; be warned, though, that once it sets you'll need a razor blade to pop the maf back out. This shit will seal an at-temp oil pan full of oil to the block with no bolts needed.

It's good shit.

Wolly6973 and I got that code recently also, just after Cobb switched to the newest version of ATR.

I never had the code until then.

I disabled it, and my car is running fine.

Hrm - that might be the thing too. What exactly did you disable and how?

In ATR,

Are you sure you didn't just suck a Civic into the intake?

Shyte - how could I have forgotten :x

Thanks Finkle :)
