corygoose Posted May 9, 2012 Share Posted May 9, 2012 I have a 99 Subaru Legacy GT 30th anniversary edition. I was first getting an egr error code. I think it was p0400. Replaced the egr vacuum solenoid, thought it fixed the problem, then it came back on, but this time it was a different error code. It was p0325 a knock sensor error code. Just replaced the knock sensor. The check engine light was off for about a week, and it now just came back on. Not sure what the new code is, but I bet its one of the 2. Are these 2 problems related? It seems like a common problem with subarus? Someone told me that there is a tube that connects to the EGR valve that gets blocked up-take it off and clean it out? Would that fix it? Do I need to clean anything else? What do you guys think? Link to comment Share on other sites More sharing options...
lmdew Posted May 9, 2012 Share Posted May 9, 2012 No the 2 problems are not related. Get the new code. Link to comment Share on other sites More sharing options...
nipper Posted May 10, 2012 Share Posted May 10, 2012 How many miles. The next one may be a O2 sensor, nothing horrible here, just stuff. Link to comment Share on other sites More sharing options...
