Angry Air Intakes and that orange "Check Engine" light

Hi everyone,

I'm having a pseudo-problem with my air intake and am wondering if anyone else has had the same problem.

Well, let me start off by saying, I think it's my air intake. I replaced the colvoluted one that came with my Impreza with a GanzFlow one. I love the extra breathing it give my engine, but I keep having problems with my check engine light turning on every few months. Every time I take it in to get the code read, they tell me the sensor is reading something funny and that it's probably related to my air intake. When my car was still under warranty, they actually replaced the MAF (or is it MAP? - MY00 Impreza TS), but in retrospect, I think they changed it to be safe, not because it was actually defective.

Anyway, the problem is this: I don't want to be spending money every few months to have them plug the car in and say "it's the air intake". I also don't want to ignore a "check engine" light that might actually be something serious (or is it EVER anything serious with that idiot light?). I guess I could always go back to the stock air intake, but that sucks (literally). My GanzFlow is so much better!

So, I have two options. Reset the ECU, (which I don't remember how to do, I guess I'll probably find it in a previous posting or some kind soul will tell me here) or go back to the factory intake. Or #3, just ignore the whole thing and have that orange light in my face all the time, which really isn't an option for me.

Not sure what I'm hoping for here except maybe some re-assurance and also just to see if anyone else has had the same thing going on with their car.

Thanks everyone!

Brian

Seems odd, I had the Ganzflow on my 00 RS for two years without a cel, swapped it for a Cobb Intake and no CEL. Do you know what the actual code they pulled was? Check it against the CEL log.

Ok first off you have a 00' there is no maf, you have a map sensor and I have never heard of them going on 00-01's. I think it could be your O2 sensor I know those years have that problem. I know a couple people with 00-01's and one was stock and had a couple O2's go on him. I think that they are trying to screw you. next time you get a light go to auto zone and have them pull the code (it's free). Write down the code that it gives you and then come on here and look up the number and find out what it is. Then if it is the O2 go in next time and say I took it to Auto Zone and got this number and it's for the O2 sensor, they'll replace it. I did that and I have an intake and it worked.

Check on the toronto club...... Erwin (Rex555) was selling OBD2 scanner and clears the code for $125cdn.... I don't know how it's good or not but it's an option.

I'd bought an OBD2 reader from Harrison R&D and love it but you need a laptop to operate it and it's $140us..... I have a CEL with my brullen but it always pops up the same code (P0420). So I just clear it every time.....

Just got off the phone with Downtown Subaru, and it seems that all 3 of my last "Check Engine" light codes were 1507, which seems to have something to do with emissions.

Apparently (and this is good info for any Canadian Subaru owner - possibly even American owners too), Subaru Canada is doing a goodwill free update to the car's computer (assuming you have a 1507 code) even if out of warranty.

The service guy told me that this is all because of something to do with gov't standards on emissions and the re-programming will allow for a wider range of acceptability so any small fluctuations in the emissions won't freak the computer out.

However, since in the past, they blamed the air intake, it goes to show you that they just love to immediately blame anything that isn't stock.

Code P1507 is:

"Idle Control System Malfunction (fail safe)"

Here's a search on this code:
