Could my subs kill my EGR valve? I replaced my O2 sensor and my check engine light didn't go off. So I had it checked again and the same problem was still there. It said that all the cylinders were running either rich or lean..... I can't remember. But I was told it could be the EGR Valve so I replaced it and for about a week the check engine light was off.Now its back on. Had it checked again and the same deal was going on. Oh there was also a low voltage reading..... which is why I'm thinking its my subs.So could it be my subs that keeps killing my EGR valve? And any solutions will be helpful. I don't want to have to replace my alternator because its in an extremely tough place to reach. And I already have a small Cap.... .5. My subs handle 600 RMS total. WOuld getting a bigger Cap help?
next time state year/make/model/mileage. most egr valves operate via vacuum. your subs can't affect a vacuum operated egr valve. if the o2 sensor didn't help out, you probably have a bad vacuum hose somewhere. that will cause the system to go into havoc because the car computer can't compensate for the excessive air being sucked in. a cap does not help with anything except for a loud THUMP. the THUMP causes a voltage spike and stresses the charging system. the cap takes care of the thump safer, it's not a complete solution.
Thank you for having such a powerful system! I am investing in hearing aids, and you and hundreds of thousands like you will make me rich in my retirement! The sub-woofers are not affecting your EGR valve. It is operated by a vacuum controlled by the ECM to regulate how much exhaust gas is to be fed back into the engine to control the NOx emissions. You want to make sure that there is no recall on the controller, or that it hasn't' failed. Follow the vacuum hose on the EGR valve to where it goes. That is the controller. Do a google search or look on Expert Village for a video.
