I have a 2005 civic DX sedan and it was throwing the codes for a bad Throttle poisition sensor (TPS) and a bad Primary o2 sensor.. I then replaced the whole throttle body and replaced the O2 sensor w/ a brand new one.. Then i had it checked again and it still through the code for the O2... I reseted the ECU by removing the fuse and all... what else could be wrong?..thanx

 

Check the plug and make sure the connection isnt loose.

 

first of all whats the code that your getting? cant tell u were to look with out knowing the code. secondly why did u automatically think that the 02 was bad?

 

Cuz the codes i was getting were po135 (02 sensor) and the tps im not worried about now cuz thats fixed

 

ok first off your car has an A/F sensor, and if you have replaced it then its probably not bad. the next place i would go to is the A/F sensor relay as well as check fuses 2 and 4 of the under dash fues/relay box. fuses 2 and 4 are the fuses for the load and control sides of the A/F relay. if the fuses are good then its probably the relay. if its not the fuses or the relay then its gonna get a bit tricky and youll need a voltmeter or DVOM. ill post up the rest of the diagnosis procedure if its not the relay or fuses. good luck bud
