Hello Guys,
Thanks for great help, With the help of the members I am able to fix P1166 and P1167 error code on my 2002 CR-V. I replaced 02 sensor by Denso 234-9005 Oxygen Sensor (Air and Fuel Ratio Sensor). Got it from Amazon for $124. (Now on sale for $100).

This fixed the problem right away, CIL light went off by just turning the key to on position.

Drove for 2 days (about 100) miles. Engine light came on again....

I am getting error code P1456 "EVAP Emission Control System Leak Detected (Fuel Tank System)"

Any help ? I suspect, I might not have seal the sensor properly by anti-seized stuff or some other issue.

you need access to a bi directional scanner to test solenoids and smoke pro to smoke the system

Apparently, couple days before I changed the O2 Sensor My wife filled up the GAS and did not tight the GAS cap as required. So this new error was for that. It been few days now since I tight the GAS CAP CIL light is off. So I am hoping that was the ISSUE.

Thanks

I couldn't find out what type of engine I had F23A1 or F23A4, then I noticed on the black plastic belt cover on the driver's side of the engine next to the valve cover, there's a white label with F23A4 on it.
Thanks for the good info. I have code 1167 and all the fuses are good. I'm going to change the air filter and run some fuel injector cleaner through the gas tank, then if that doesn't help I'll buy the Honda part for a SULEV (currently $310.00 + tax) unless AutoZone can prove to me that their $119.00 Bosch version will work for a SULEV. I also noticed a Denso version which has the right Honda part no. for $189. on Amazon.com.

Looks like my O2 sensor failure might have been caused by using too hot spark plugs. The failure occurred awhile after I installed E3 Diamond Fire spark plugs on the advice of a friend. Since then I've had several ignition components fail along with the O2 sensor, and a mechanic traced it to the plugs causing a domino effect of component failures by putting a strain on the ignition and emissions systems. Best to stick with stock Denso plugs if you haven't beefed up the rest of your systems. Mine is stock and stock Hondas are very sensitive. $2000 lesson learned. I have since heard from another friend who tried the E3 plugs in an Audi and had the same problem later on. Fried the coil...

I wanted to post something on this problem because I had such a hard time with it. I kept getting the same "check engine" error that everyone else was getting. I replaced both O2 sensors with both Bosch and Denso brands and the problem kept coming back. I found out by calling the dealer that I had a California emissions engine and that I needed a "special" O2 sensor that costs $330. I took the vehicle to my mechanic and he called a friend of his that specializes on Hondas. He told him that certain Hondas with ULEV VTECH engines do require a special sensor. He suggested that I used Bosch 13493. It worked. Hope this helps someone out.

Can you please tell me is this Bosch 13493 for the '02 CRV EX? I have both of the codes P1166 and P1167 and would like to make sure I get the correct part for my '02. How would I tell if my engine is the ULEV VTECH? I did buy my CRV on the East Coast so thinking it is not he ULEV but need to make sure of that also. Any and all help is appreciated as I am a single mom and have someone to install this part, but I just have to get the correct part for my Honda. Also any suggestions where I can acquire this part as inexpensive as possible. Your assistance much appreciated. Thanks.

Hi Meinmd,

My Accord has a windows sticker on the left rear window that says SULEV (Super Ultra Low Emissions Vehicle). I"m not sure if the ULEV CRXs also have that or not. Also, and more obviously, it should say it right on the engine. Mine is stamped with "SULEV-VTEC" in big letters right on top of the fuel injection unit.
If your's is from the East Coast there's a good chance you don't have it, but in any case, stick with the OEM parts, or Denso brand.

I got the same error for my '02 Honda Accord EX with ULEV. Has anyone tried using Bosch 13512 part number? I've tried all places for a suitable sensor for my vehicle but none of the store guarantee that my codes will disappear and refuse to take back the product if it doesn't work. I'm over due for inspection and just want to get the part that works. Please help me with your experience on which part is best for ULEV engine.
