A few months ago my 98 civic hx 5spd threw the oxygen sensor code. I tried cleaning it a few times, but it always threw the code again. So I replaced the sensor (which was $400) and it threw the code again just as quickly as did the times before? The code its says is a slow response from the bank one sensor. Any idea to what would be going on would be greatly appreciated.

 

what code did you see and how did you get the code to show up?
Where is a table to show what code means what ?

 

is it a 4 wire o2 sensor?
Is yes
the 2 black wires are the heater wires
you should measure 50 Ohms accross them
If over 1000 ohms replace it

 

make sure u use a Honda Ho2s.Possible Pcm issue
