mikec03 Posted January 16, 2010 Share Posted January 16, 2010 My '95 Legacy just came up with a P0105 and 0106 code. This is supposedly a MAP problem [manifold air pressure]. I've searched here and on the internet, and looked at the engine. There are no hoses loose and I can't see anything that looks like a MAP. Does the '95 really have a MAP? I really can't sensel any drivablilty issues. Can anyone shed light on this? Quote Link to comment Share on other sites More sharing options...
Durania Posted January 16, 2010 Share Posted January 16, 2010 I didn't think '95 model vehicles would return with OBDII check engine codes. Quote Link to comment Share on other sites More sharing options...
Mike104 Posted January 16, 2010 Share Posted January 16, 2010 (edited) I thought the OBD II codes were 1996 and up? Q. Where is the map sensor on 1995 subaru legacy l wagon? A. The Map sensor, (Subaru simply calls it a "pressure sensor") is located on the passenger side on the strut tower facing the Air cleaner.(US cars). The part itself has a 3 wire connector, and a single vacuum hose coming out of it. The part is about 1 1/2 inches wide and utilizes 2 mounting bolt holes. Take note that only "one" of these holes is used for mounting. No picture though! Here is a photo of the sensor: Edited January 16, 2010 by Mike104 Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted January 16, 2010 Share Posted January 16, 2010 (edited) subaru went OBD2 a year early, 95, at least in the legacy line in the US. there is some debate about the impreza line and a recent thread to prove it. and regarding MAP vs MAF, the 96 lego is maf, and i "ASSUME" 95 lego is as well, but i don't really know. i have both and never noticed a difference, but i never really looked for it either.

Olnick Posted January 16, 2010 Share Posted January 16, 2010 Subaru started OBD2 with the '95 model year. They had a MAF sensor, not MAP. Quote Link to comment Share on other sites More sharing options...
mikec03 Posted January 16, 2010 Author Share Posted January 16, 2010 Thanks for the help and picture. I found it! It's a lot smaller than I though that it would be. The '95 is OBD2 complient and it has both a MAF and a MAD. I have no idea why it would have both. Now if I can figure out why the code has come up, I'll be set. The contacts are clean and the tubing seems to be in place OK. I'll reset the code and if it comes up again, I'll go to the junk yard and swap it out. Thanks again.

johnceggleston Posted January 16, 2010 Share Posted January 16, 2010 is the tubing old and cracked? Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 16, 2010 Share Posted January 16, 2010 95 should have both MAF and MAP. The MAP is a tiny little thing on the front of the passenger strut tower. Has a solenoid right next to it. I know Mike said he already found it but for those who don't know... P0105 Pressure sensor circuit malfunction. Check the wires for splits/ breaks in the insulation. Make sure the connector is clean inside. Make sure the sensor is receiving more than 4.5V at pin 3 on the sensor connector.

Olnick Posted January 17, 2010 Share Posted January 17, 2010 95 should have both MAF and MAP. I believe 95s have the MAP sensor only if they are AT. Sorry, since I drive a manual transmission I didn't think about that! Quote Link to comment Share on other sites More sharing options...
Mike104 Posted January 19, 2010 Share Posted January 19, 2010 Took a look at my 99 OBW 2.5L 4EAT and found both a MAP (now that I know what it looks like!) and a MAF. Quote Link to comment Share on other sites More sharing options...
