Family and I just got back from a trip, and the next day check engine light came on. I was working so couldn't look at it for two weeks. My wife limped it around until I could get the code read, and get parts. 100 miles on over half a tank of gas. Took Baja to AAmco they read code for free, and told me if I couldn't fix it bring it back and they would. I smiled and thanked them. P0030 was the code they gave me. Search button, Google button ect. 02 senser OK order parts fix next weekend. Called Subaru and sensor (upstream was gold(can't remember I think I passed out) and downstream was pure silver($210). Rockauto it is $102 and $60. code was for the air fuel upstream but I say replace them both if you can. I also notice I had a slight exhaust leak after the resonator. Fix went like this unplug both sensors be careful. wiggle em. Pull plastic shield There wasn't enough room to get the socket in without dropping exhaust anyway Unbolt the exhaust I used WD penetrating oil. exhaust bracket exhaust at heads drop exhaust use penetrating oil a few times to break them loose replace sensors remember to use anti seize on threads put them in the right locations notice the connectors I cleaned off the places that meet gaskets with sand paper I ordered new exhaust bolts because I usually break them reused old ones, the new were too long on the neck too short on the thread. Hang the exhaust on hanger then put head bolts then remaining exhaust all loose then tighten all bolts. I used zip ties to keep wire out of the way. Total time was about 2 hours and about $200 not including beer. I hope this will help someone with same problems, save $400 and get back on the road. -
Hey everyone, I just bought my first subaru a few weeks ago. Its a 99 legacy sedan L sedan. So far I like the car, I think I lucked out getting a 99 since its the base model but I still have the sunroof/spoiler/alloy wheels combo. Its a 5 speed standard too which is fun since I spent the winter in an automatic jeep cherokee. I paid $800 for the car which has 155,000 miles on it. When I bought the car the man who owned it told me the check engine light was on for a front 02 sensor. When I had the codes checked it turned out it had codes for front 02 as well as a knock sensor. I replaced the knock sensor and it seems to be running more smoothly already. My main question and motivation for posting this thread is this: When I jacked the car up to change the oxygen sensor, the source of my exhaust leak became obvious. I have a fairly significant leak coming from where the header meets the manifold. It looks like the flange is pretty well rusted out. Is it possible that this leak before the 02 sensor could be causing the code? I was thinking of replacing the sensor to see if it would clear the light, but I feel like that might be a waste of time since the leak might be the reason for the code. I was thinking of ordering a replacement header, which runs about 140 bucks from advance auto in town, but they'd have to order it anyway so I'm looking around a bit for better prices. Should I replace the header & o2? or just one or the other? -
