Eduardo Andrade Posted June 2, 2012 Report Share Posted June 2, 2012 (edited) I have a 97 Saturn SL1. I just bought it maybe almost 2 months ago. The first month I didn't really get to use it cause I didn't get to get my plates until the second, but I drove it around for fun a couple times around the neighborhood. It's not till this month I started noticing that there's sort of a rattle, I'm not sure where it's coming from but it sounds like it's coming from the exhaust. My first time I filled my tank was not too long ago, and I added chevron techron. I also just changed the oil today. But before I changed the oil and after I used chevron techron, my check engine light came on. I went to autozone and they gave me the code, it's P0133, the definition on the receipt is: H02S11 slow response (heated oxygen sensor bank 1 sensor 1). I'm no experience mechanic (obviously), but I was hoping you guys could help me solve this problem and tell me what I should do first. Oh yeah, and I know the rattle and the oxygen sensor problem are probably two different problems, but I was hoping you guys could help me fix both.

KillaCam Posted June 2, 2012 Report Share Posted June 2, 2012 Replace the sensor? You may be running rich from it too. But I'm no mechanic either.

deathcards Posted June 2, 2012 Report Share Posted June 2, 2012 the rattling could be from a heat shield i know on my impala i have one that rattles when i rev the engine could still be something else though Quote skar sk2500.1 0 gauge power and ground kunukonceptz alpine HUvxi65 components on BA gt-275new build log -> http://www.stevemeadedesigns.com/board/topic/150642-project-d-kon-deathcards-build-log/#entry2148821 2 x-15 sundowns singer alt, odyssey bat, and maxwell ultra caps Link to comment Share on other sites More sharing options...
OrionStang Posted June 2, 2012 Report Share Posted June 2, 2012 Rattle could be a ton of things. I would say you have fucked up catalytic converter is causing the exhaust to back up causing the high temp code on the o2 sensor. The rattle could be the catalytic element has broken loose inside its case. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
Team808 Posted June 2, 2012 Report Share Posted June 2, 2012 Ya its not going to be a converter, they rarely go bad .But it sounds like the 02 sensor went bad. A slow response does not mean you are running rich. Seriously you guys are picking things out of your asses, if you dont know or even have a clue ,you should probably not say anything . Best thing to do is clear the code, and see if it comes back on .If it does, then it needs to be hooked to a scanner to see the actual 02 readings . Or you could take the chance and replace the sensor . Your call. Quote Member of Team 808 Member of Team North East Spl Link to comment Share on other sites More sharing options...
Eduardo Andrade Posted June 2, 2012 Author Report Share Posted June 2, 2012 I forgot to mention the rattle is only at certain RPM's. It's most audible at ~1600. My uncle said it could be the exhaust and he was the one to point it out to me, and that's when I payed attention and actually heard it. But this was on a hotter day and at a lower RPM, it's now cooler and only happens mainly at ~1600. I've read online and I have also read that it could be the heat shield. As for the o2 sensor, OBD scanners can read that too, right? So I can take my car back to autozone and ask them to clear the code, use it like normal and see if the light comes up again, if it does, autozone should scan the o2 readings, right?

OrionStang Posted June 2, 2012 Report Share Posted June 2, 2012 Who's puiling stuff out of their ass? Its a POS Saturn that is 15 years old. All or part of the catalytic element can break off inside. This could cause the rattle sound, this could cause a slight blockage, that could in turn fuck up the o2 reading and damage the sensor.

howelr Posted June 2, 2012 Report Share Posted June 2, 2012 (edited) I'd say its a heat shield. My Del Sol did the same thing, took off the cat and the heat shield fell off into pieces then just put it back with new bolts from O' Reilly due to the originals being so rusted Edit: The rattling that is. I dont know about the O2 sensor. Im no mechanic either but my o2 sensor is right on top of my cat under the chassis Edited June 2, 2012 by howelr Quote Link to comment Share on other sites More sharing options...

miklgagne Posted June 2, 2012 Report Share Posted June 2, 2012 for the rattle get underneath it when its rattling and look if you can see where its coming from. Probably as many have mentioned a part of your exhaust system, heat shield or otherwise. Quote Link to comment Share on other sites More sharing options...
