I have about 63K on my 2006 and my Check Engine light came on for the very first time yesterday. I pulled over and checked the manual and then the gas cap before going to the dealer to have it checked out. They came back and told me the rear O2 sensor had failed. I have always used 93 Octane so was a little surprised that it failed so relatively early in its life (as was the mechanic).

Has anyone else out there had a similar issue at this mileage or earlier? I'm also wondering if there's anything that I (or a valet) could have done while driving to cause this premature failure? Anyone replaced this themselves? I just paid $300 to have the dealer order the part, and they'll probably need another $200 to install it so if it is easy, I might try it myself.

Thanks.

 

Simple job! Go to Advanced Auto Parts, rent an Oxygen sensor socket (you get your money back once you return it). Just jack up front of the car and put on jack stands. Unplug sensor and use a rachet and 02 sensor socket to take out sensor. Put new one in and and plug back in. Take jackstands off and start up car. Check engine light should be gone.

 

It seems strange that it failed with only 63k miles on it.

Some additional points to note:
Remember to wait for the exhaust to cool off.
Expect rust and other debris to fall off when you touch the exhaust. Wear safety glasses or at least be aware of what's above you.
It should include anti-seize as well. Apply a small mount to the thread prior to installing the new one.
While the car is on jack stands, you can do you oil as well.
If it's up on four jack stands, you can do you MTF, diff fluid, and flush your brakes as well (every 3 three years, so you might be due for a 2nd brake flushing).

 

Quite common for the catalytic converter core to come lose and whack the O2 sensor, killing it. Replace O2 sensor, works for a while, then gets whacked with the loose core and you haves to get yet another.


FWIW, i was at ~75k miles when I got a "bad O2 sensor" reading. From searching threads here, and hearing a rattle in the exhaust, I determined that it was the cat, and did NOT want ot buy a new O2 sensor only to have it get wiped out. The Honda dealer said they'd check it, but that it was on my dollar if the cat was OK. IT wasn't. So I got a replacement cat under 80k emissions warranty IIRC I did have to buy the new O2 sensor.

 

Primary O2 sensor damaged @ 65 000 km.
Bought a Universal Bosch Lamda and took a few minutes to put together and a few more to pop in.
Dont remove while exhaust is warm as this can strip the threads.

 

I have an 07 with 22k miles and the check engine light came on recently. Checked the code and it returned P1172 and P2A00 (O2 Bank 1 Sensor 1). This refers to the upstream (before cat) O2 sensor which is actually referred to as the air/fuel ratio sensor. Talked to a dealer and found out that there was a service bulletin explaining that not only does the O2 sensor need replacing, but the ECM needs a software update as well. I believe some 2006 S2000s are included in this service bulletin as well. Also, rockauto.com has the same Denso OEM 02 sensor for about $145.

 

Get your 02 sensor from www.oxygensensors.com for about $45. OE direct replacement. Or search on Amazon using the 02 part numbers (not Honda part numbers) for even a little less.

 

Yeah no kidding never let honda do small stuff like this. It is a very easy fix and can be done very cheap. O2 sensor fail just get under the car and replace it.

 

Bumping an old thread.... Ive been trying like crazy to find the Mfgr that makes the Primary OEM o2 sensor and a replacement for it without paying $200 for a new one.

Is NTK the OEM mfgr?

Seems this is the OEM sensor , can anyone confirm?
NGK 24417 Oxygen Sensor - NGK/NTK Packaging

 

Denso makes the OEM. Rockauto has good prices. Sensor #1 is reasonable, but sensor #2 is pretty expensive.
