Hello. Today just pop up 2 codes one in relation to low voltage and other O2 sensor bank 1 sensor 2. Question is can I drive with bad O2 sensor 2-3 weeks because in my big 1 million people city they do not have in stock (I just cannot believe !!!) and the price is $260 order online 2-3 weeks shipping time. About low voltage is this about bad connections between battery terminals ? or somewhere around alternator ? 2 weeks ago my battery light after I start engine was about 3-4 min on but later till today it is ok. I start engine today battery light going off. Live date says 14.4 VOLT engine running..I am in Canada so condition are cold, snow and salt everywhere... thank you for input :) cheers

Towards the rear of the catalytic converter. "Downstream".

That link has pictures and a video. Before spending the money, for sure look at the wire harness for damage, and disconnect/reconnect 3 times to assure that the connections are not just corroded.

You can probably drive a couple weeks with the code displayed.

+++++++++++

Regards the voltage, was the battery light on when you observed that 14V 'live reading'?
You could have a low output alternator, worn serpentine belt or weak tensioner, or bad ELD (Electronic Load Detector). Gotta troubleshoot some more...

Carbuff2 thank you very much for reply... always can rely on you :) I will do as you said. I will check (O2 sensor connections) it next my off day before I buy new one. Thank you for video link. About low voltage .. I am not so much incline with it but I am trying. To answer your question .. was the battery light on when you observed that 14V 'live reading'? No it was not. I just check voltage yesterday with OBD. When battery light was on about 3min after start engine car was few day not driven and it was like -20 C outside so I thought it was just malfunction and praying that will vanished :) I was going to work back then..... I will google what should I check step by step in relation for this low voltage issue.. Thank you again !!

Hi Carbuff2. I just wanted to let you know that I followed your instructions and cleaned O2 plug and erased codes so far running good !!! Alternator I did not check everything yet but is ok for now and no codes. Do you think is good to buy and changed this serpentine belt ? I have this honda from first owner and I do not see in history that has been exchanged ....thank you !!

We replaced our serpentine belt just as Good Practice at around 120,000 miles. No issues before or after.



Replacing it is a lot easier with a Serpentine Belt Tool like this due to restricted space


The 'cool' thing about the Harbor Freight tool is that the wrenches are embossed 'CR-V", LOL
:cool:

Thank you for link. I will check how much they want with shipping to Canada. I was thinking to buy special Honda tool it cost $98 CAD but this Harbour Freight looks good and it is your recommendation so it has to be good !! Thank you.
