my 99 legacy's obd-2 says the map sensor is shot. i have read that subaru's had a maf then map sensors. my car is a california emissions car with a 2.2L and auto tranny. any help would be appreciated.

thanks,

IIRC, only the first couple of years of legacies (90-91 or 92) utilized a MAF sensor.

Mass Air Flow sensor? It wasn't just the first ones...it is in all. It is what connects to the box the holds the air filter.

 

 

I got one on eBay for $10, and one at a junkyard for $80. It really killed my gas mileage when mine died. A used one would work fine, if you can find one at a good price. Mine came off a older EJ22 Legacy...so they outta all be about the same.

 

MAF are up until 1999. 2000+ used MAP.

I think my car (California '96 Legacy) has both. Is that redundant? I can see a MAF sensor right after the air filter. I'm fairly certain the thing bolted down right behind the air filter box, with the vacuum line and a wire harness attached to it, is a MAP sensor.

Perhaps...maybe something to do with emissions?

Did you have other symptoms?

T.I.A.

Well, it was my fault it died. I put an open air intake on it, and it sucked a lot of dust in, so I was cleaning the MAF with alcohol and a Q-TIP and it ran like crap and gas mileage was like 12 MPG.
