Looks like I may have a faulty oxygen sensor per the fault codes being thrown. It is related to this thread of mine: http://www.ferrarichat.com/forum/360-430/461945-need-help-cel-fault-codes-please-p1135-p0152-p0154.html Would someone be kind enough and tell me where the oxygen sensors are located please? Dan
None, no issue at all. Engine runs perfect. I am now thinking its possible the codes are being thrown because I have Tubi exhaust. Perhaps I should start another thread and ask the Tubi owners if they get CEL oxygen sensor codes too post Tubi exhaust installation. Dan
Cat-back exhaust should not give you CEL codes. Though, the Tubi exhaust probably eliminated the exhaust valves (should be #37 in above diagram), and you need to plug the vacuum hoses previously connected to the stock exhaust valves. I would check that. If headers (with pre-cats) or main cats were changed/removed then all bets are off, but you seem to have stock headers and cats, so that shouldn't be your issue.
Thanks for the info. It appears Tubi is not the culprit for the CEL. I will check to make sure the vacuum hoses are capped and start checking the oxygen sensors. Thanks again. Dan
