Hey world just want to let you know how I solved these trouble codes research research research hey I found bits and pieces of information on these DTC for a Infiniti g 35 2005 so I've been sold one day I was been driving all right went to Payson and my car has been running good for the since I bought it well one day I got in trouble code and it said catalyst manifold and I know that I had nothing to do with catalyst for the cats so I read up on the forums and they was talking about it might be the old two sensors so my dumbass goes to eBay and buy some faulty parts and tries to put them on my coop or my sedan and and they didn't work so I was frustrated and I didn't even replace what I should have replaced so I took it to the shop and they charged me $300 to change out the o2 sensors upstream and downstream and they didn't even reset the ECU and they didn't even reset the idle because from what I heard from these forms that the computer has a signal that descends to the sensor because it's programmed to do that and if the new sensors are getting the old signal from the old sensors then your code might pop up if you if this is the problem with your what's your sedan so fingers crossed I changed the o2 sensors hoping that it would be the code will go away after 15 minutes 15 miles of driving the codes came back and I thought about it and I was like well they just changed the o2 sensors it should work now but then I also remembered about the form what it said that you had to reset the ECU and and the idol so what I did is I just unplugged the air mass airflow sensor and I did the pedal dance by resetting the ECU or you hold it down or what is it 12 seconds and then you you hit the pedal five times and if if you guys do more research then you'll find it you'll find it on here well I'm just letting you know that I did solve the problem and I did get rid of that code so all I did again was when I replaced the o2 sensors I just reset the idle and I reset the values in the computer system for the for the signals to go to the o2 sensors so I hope this guys I hope this helps you guys and narrowing down the problem from cuz what I heard every time you replace anything to do with the throttle body or exhaust manifold or even the intake if you don't reset those values I guess the code can still pop up so I would try that first we start before you start throwing money at it and I hope this post helps you guys thank you very much.
