2009 Honda CR-V code P2A00 02 sensor replacement

replacing a oxygen sensor on a Honda crv

[@eljeffe8806]

I gave Scrap Daddy a thumbs up as soon as I saw him wearing gloves!! I'm with you on that. Sometimes the biggest challenge on these sensors is getting the connectors apart without damaging them.

@@eljeffe8806 Thanks for watching! I appreciate the feedback

[@skylinefever]

I think my mom's car will need this, as the MPG has declined. The plugs are good, the dust boots are good, the intake has been cleaned, and the MAF has been cleaned. Thanks for showing me where this stuff is.

Thank you, very helpful. I received the exact same code on my 2008 CRV.

Hi. Many say the o2 sensor upstream is the one with a cup in the manifold... But you are right its under the car and before the catalyst converter. But it the rear one, (after the catalyst) is it the same sensor, because its not clear? Thanks

[@scrapdaddysgarage5027]

It is a different part number NOT interchangeable. Thanks for watching. Please subscribe if you haven’t already.

@@scrapdaddysgarage5027 its funny, because I don't fins it on the Honda dealer parts.

[@malibuman8941]

Before going to the parts cannon, I would verify for electrical connectors for good continuity, any other error codes such as misfires.

[@sharune007]

Is the bank 1 oxygen sensor the same as upstream sensor and should I change the other sensor(downstream)at the same time? How was the cost of sensor? Thanks.

[@scrapdaddysgarage5027]

Bank 1 sensor 1 is upstream. Bank 1 sensor 2 is downstream. I only change the bad one. I prefer Denso senders , they cost around $120 dollars. Thanks for watching

[@TaimurBaig87]

very nice video looks very easy DIY... my code is P0140 do you think its bad O2 sensor or it could be some thing else ?

[@scrapdaddysgarage5027]

With a po140 code I would look for damaged wiring or poor connections at the plug before replacing the sensor

[@TaimurBaig87]

@@scrapdaddysgarage5027 okay will do thanks for quick reply

[@TaimurBaig87]

Just curious did you had to remove any shield covering up the O2 sensor? If so what was the size of the bolt or nut. Just asking because i dont have the car its at my fiancee home and i might have to do this repair at her drive way... Plz let me know what else ill need besides 7/8 wrench

[@scrapdaddysgarage5027]

Taimur Baig no shields to remove, its just like what you see in the video

[@paulhak465]

Do you need to unplug the battery first before installing new sensor?

[@scrapdaddysgarage5027]

No you don’t. Thanks for watching!

[@key2products]

Thanks, Very helpful... man those clip are a pain!

[@scrapdaddysgarage5027]

Thanks for watching!

[@tteuvky]

you vehicle is idling at 1000RPM, is that normal. mine also idle at this speed after cleaning throttle body and replacing PCV hose plus i get check engine light saying idling higher than expected.

[@scrapdaddysgarage5027]

On a cold start it will idle around 1000 then it will settle to around 800 rpm’s

[@tteuvky]

@@scrapdaddysgarage5027 mine doesn’t get back to 800, it says at 1000.

[@leeannlubinski4131]

changed out both 02 sensors on my 2009 crv and took battery cable off for 1/2 hour and check engine light still on? any ideas whats next? thanks dan

[@scrapdaddysgarage5027]

Check the codes again and use the scan tool to turn off the light. If you get the same codes you probably have a wiring issue, the plug or the wiring may be damaged internally, and unfortunately this is difficult to trace. I wish you the best.

[@malibuman8941]

possible wiring issue or corroded Molex connectors. try cleaning them.

[@marvinhuezo43]

where did you buy this piece

[@scrapdaddysgarage5027]

My local auto parts store, Thanks for watching be sure to subscribe.

[@the_mind_of_pandabear5278]

If sensor is replaced, Engine light will remain on? I have to delete error code?

[@scrapdaddysgarage5027]

I usually delete any codes, The engine light will turn off by itself eventually. Thanks for watching! Please subscribe if you haven’t already 👍

[@yanglee206]

Do you need to have that code scanning device to erase the code?

[@scrapdaddysgarage5027]

You can disconnect the battery of the car to erase the code, but the radio memory will need to be reset and some Honda’s need a security code to do that. It is best to do it with a scan tool. Thanks for watching

[@eddienakamura4334]

It’s the one before converter? On top?

[@scrapdaddysgarage5027]

It’s before the converter, but on this year crv it’s under the car, thanks for watching be sure to subscribe if you haven’t already

[@Drayelam21]

No heat shield ? Is it necessary to have one

[@scrapdaddysgarage5027]

Not necessary, just don’t park it a pile of dry leaves!

[@mbeck3132]

Thank you well done

[@nasseranise102]
