Hey Everyone,

I need some help. My 00Excoupe only has one o2 sensor thought this was kinda wierd, or is it normal...Does anyone kno if it would pass emissions in PA.

 

If it has the stock motor in it then it is supposed to be OBD2 meaning 2 o2 sensors... 1 in the header downpipe and 1 in the catalytic converter. If the motor is swapped then it may well only need 1 o2 depending on the motor. Is the check engine light on? If the check engine light is on it will not pass emissions.

 

It's supposed to have 2 and if it doesn't then it won't pass emissions,

 

well long story short my cat clogged completely which is really wierd and it was throwing o2 codes and my car wouldnt start.. I took it too my mechanic and he couldnt figure out why it wouldnt start my check engine light never came on because its disconnected or something havent got to it yet..But my mechanic said he couldnt find a second o2 sensor i jus didnt kno but it is the origional motor..
