I am having a problem with my secondary O2 sensor. I took it to a shop and the guy there hooked up the OBDII scanner he had to my car but it didn't pull a code but the check engine light came on. On the OBDII scanner the Secondary O2 sensor said it was on but the voltage was 0 even after ideling the car for a long time and even after I drove it. What would cause the O2 reading to be 0 even though it said the sensor was on. Also what is the voltage supposed to be for the Primary O2 sensor. Using the SnapOn OBDII scanner the voltage was fluctuating between 2.90-3.10. By the way I have a 98 Accord Coupe with a converted manual tranny.

i have an o2 sensor i can sell you, i have a 98 accord, and i got a catalytic converter for sale as well, both are OEM, but both parts are off a 2000 accord

Well I don't know what the problem is so I don't want to buy it if I don't have to. Does anyone know what it could be.

my bad man, what i meant is, if u find out its a bad o2 sensor. it'll cost like $200+ new from honda, mines is good condition, i'll let it go for much cheaper, barely used.

from what i read about it but not 100% sure, u will end up changing ur o2 sensor either way u will have to change it soon or later if u havent, and the catalyst converted is most likely good cause what usually happens is if u drive the car for a longggg time with the 02 sensors bad then the catalyst converted will get fuk.
oem o2 sensors lifetime warranty from autozone goes under $200 for the most expensive one, and is soooo damn easy to change them i regret paying. but then again i am a noob

Does any one know what the voltage is supposed to be on the primary and seconadary O2 sensors?

strykernyc

output of the sensor is usually between 0 and 1.1 volts.

k too much info here and read all if u want to really understand and i am sure this is ur solution. here u go do the reading finally found something

Do you know what it means if the voltage reading is between 2-5 volts? My primary O2 is reading between 2-3 volts under idle and jumps up when under load.
