SlightlyEvil Posted October 11, 2007 Share Posted October 11, 2007 I'm sure the answer will make me look stoopid, but since its usually considered best to take the stock front EGT probe out when replacing the stock catted 2005 up-pipe with a catless one in case it breaks apart due to increased flow rate and makes love to your turbo, would it not also be smart to take out the front O2 sensor in the manifold just before the up-pipe since there's nothing stopping it breaking apart? I'm assuming the O2 sensor is just made of much tougher stuff (ceramic I think right?). Link to comment Share on other sites More sharing options...
rao Posted October 12, 2007 Share Posted October 12, 2007 It does not pose a danger, it is designed much differently than the egt sensor. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...

SlightlyEvil Posted October 12, 2007 Author Share Posted October 12, 2007 Well if it was a risk to the turbo I'd take it out. Link to comment Share on other sites More sharing options...

rc0032 Posted October 12, 2007 Share Posted October 12, 2007 If you take it out the car wouldn't run Ya it would just put it behind the turbo :lol: Link to comment Share on other sites More sharing options...

SlightlyEvil Posted October 12, 2007 Author Share Posted October 12, 2007 If you take it out the car wouldn't run Sure it does, I just tried it for shits n giggles last night. (I was really bored, ok?) Posts the obvious P0031 CEL & Binking flash. Car ran fine though with an 18mm bolt in the hole. Link to comment Share on other sites More sharing options...
rao Posted October 12, 2007 Share Posted October 12, 2007 Well there you go, most of the sensors are there just for fun It really never ends, does it?? Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
SlightlyEvil Posted October 12, 2007 Author Share Posted October 12, 2007 haha well i dont know much about cars let alone mine so I'm always interested to see what affects what in what way. well, within reason. Link to comment Share on other sites More sharing options...
Infamous1 Posted October 12, 2007 Share Posted October 12, 2007 ^^^ Im am going to go out on the limb and guess you have no clue what an O2 sensor does? Link to comment Share on other sites More sharing options...
bradlgt21 Posted October 12, 2007 Share Posted October 12, 2007 LOL yeah those check engine lights are there just for decoration. And Air Fuel Ratio meters are just for show too. Just a clue when installing a Air Fuel Ratio meters you tap into the O2 sensor. Lets see if a light bulb goes on now. Link to comment Share on other sites More sharing options...
PhilT Posted October 12, 2007 Share Posted October 12, 2007 Watch out for that EGT sensor, they break apart just by looking at them Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...

bradlgt21 Posted October 12, 2007 Share Posted October 12, 2007 Isn't that what the cat is for? filtering out the exhaust?? Link to comment Share on other sites More sharing options...
SlightlyEvil Posted October 12, 2007 Author Share Posted October 12, 2007 Like I said, n00b. I assume it detects the levels coming out of the exhaust and makes adjustments to the AFR accordingly? Sorry pls don't flame me for my ignorance! Link to comment Share on other sites More sharing options...

SlightlyEvil Posted October 12, 2007 Author Share Posted October 12, 2007 So what WOULD happen if the O2 sensor was removed? Car run rich/lean/wrong boost/enter a timewarp? I assume O2 sensors do occasionally die and people have to drive to a service centre to get it replaced... Link to comment Share on other sites More sharing options...
SlightlyEvil Posted October 12, 2007 Author Share Posted October 12, 2007 nobody? Well I assume it'd just run rich since it'd interpret the missing sensor as 'low voltage' no? Link to comment Share on other sites More sharing options...
qikslvr Posted October 13, 2007 Share Posted October 13, 2007 I don't know about running rich, but it will run like crap and cause the check engine light and cruise to flash. It might be possible to drive it to the dealer, but not much further than that. Let's kick this pig! Link to comment Share on other sites More sharing options...
SlightlyEvil Posted October 13, 2007 Author Share Posted October 13, 2007 Ahh yes but in the interest of knowledge, why would it run like crap? I mean when the thing is at full throttle the O2 sensor isn't even in use I don't think is it? I thought modern engines stop paying attention to o2 readings at full throttle to prevent a misread and making the engine run too lean or something - or so I was told by the dealer.

tommypenguin Posted October 13, 2007 Share Posted October 13, 2007 I would assume your car would run terrible since its losing a reading that is directly used in calculating the appropriate air/fuel mixture based on your atmospheric conditions at the time. Anywho, I wouldn't do it, nor attempt to find out the impact of its results on my ride just because I would hate to have to replace a motor because I decided to play the mad doctor one night in my garage....

I thought modern engines stop paying attention to o2 readings at full throttle to prevent a misread and making the engine run too lean or something - or so I was told by the dealer. The o2 is always in use, seeing how you always are using it to calculate the correct a/f mixture. Every 'modern' engine has an 02 sensor and use it at all times while the car is running. The only time the o2 stops paying attention is if you are a boring driver, try telling it some jokes to get its attention back. Even though there are flamers on here, myself included at times, its all in good fun and its better to get educated than to be silent and clueless. Keep asking away until you get the answers you are looking for. Link to comment Share on other sites More sharing options...
