please help what is it? and what does it mean?

 

Heated Oxygen Sensor (HO2S) insufficient switching bank 2 sensor 1 (Front Bank)
This DTC indicates a degraded O2 sensor affecting performance in the response switching, transition time, or ratio. I would say you need to replace this sensor.

Also check my post HERE on degraded O2s

 

thank you very very very much. guess i gotta get a nrw o2. which side o2 driver or pass?

 

thanks for that post. its very informative.

 

Bank 2 is on the drivers side. Sensor 1 is before the CAT.

 

thank you very very much. im sorry im dumb when it comes to this stuff

 

um isnt bank 2 the passanger side? B1S1 is the front drivers side(pre cat) and B2S1 is the passanger side(pre cat)

I mean when my B2S1 went bad I replaced the front passanger side and it fixed the problem.

 

98TAauto your right. B2 is the right hand side opposite #1 cyl. That's passenger side.

Thanks

 

HAHAH, just making sure No biggie, i just dont feel like hearing Larry whine cause he had to take out the wrong 02 :-P LMAO

 

HUA!
