We've replaced ALL vaccuum lines dealing with EGR, tested EGR and good, EGR solenoid is good, blown and cleared ALL ports regarding EGR, checked metal line for EGR and was clear and code still comes up after running, took to mechanic and he checked and redid everything we did and consulted a fellow mechanic and can't figure it out. What else could it be?
So, from your post we can determine it is a 1974 to 1999 model Subaru with a boxer engine, unless its a 2001 up H6 with an EGR malfunction or circuit issue.
General questions can only get general answers. EGR systems on Subarus varied in style and function.
How did you check the EGR solenoid?
How did you check the EGR Valve?
Did you check the operation of the transducer?
Do you have an exhaust leak?
Did you check all the electrical plugs and connections for clean and tight? No corrosion?
Have you checked the MAP/BARO sensor?
Did you check the ECM circuits?
Is the 400 code the only one? Are there or were there others? How soon after you drive it does the MIL illuminate?
Depending on the year of the car, and your current weather when this is occurring, there is also a chance that ice is developing in the vacuum hose to the MAP. Subaru had a fix for that.
we have a 97 imprezza 2.2l auto we checked egr with vac guage. tested solenoid by powering it with 12v and blowing in it and was working good. what you calling transducer? what? how am i checking map/baro sensor? ecm circuits?PLease explain?
I have a question when blowing into the BPT do I take that hose off on the back of it? I've got the same issue on my 98 Outback I want to narrow it down first before taking off the pipe that heads to the head just because I had issues trying to get the top part off when I did the HG's.
I've seen lots of posts here and elsewhere on the following problem: Your power seat won't move front <-> back. So you want to take out the seat to get to the mechanism. Removing the seat, as described in shop manual (and there does not really seem to be a way around it other than cutting...
Howdy lads. Need some advice? Where can I find the crank angle senser for my 2010 outback diesel boxer engine. 2.0lt.
Car keeps cutting out on the road very dangerous

Hi - I got a brand new Outback 3 weeks ago.
car is in break-in period, but I am noticing that i can never get more than 20 mpg even though i drive carefully.
Is this normal ? Pls share your thoughts.
