  1. Gen 2: 2002-2006 (UK 2002-2007) CR-V
    Hi All, I took inspiration from a post on this forum to replace my 2003 CRV's front O2 sensor. I am a newbie at cars and this is the first time I am trying to fix anything in any car. I slid under the truck and located the O2 sensor. I see that the O2 sensor's electrical connection is very...
  2. Gen 2: 2002-2006 (UK 2002-2007) CR-V
    I recently bought a 2004 Cr-v automatic transmission used, haven driven it a while i observe that the V is running low on mpg. A visit to mechanic reveal that there is no Oxygen sensor installed in the entire exhaust system, the car run pretty well with no check engine light. My question here in...
  3. Problems & Issues
    Friend has a 2000 Crv-se. oxygen sensors are bad and she already ordered the sensors online. They come with the connectors etc that plugs in like oem. I looked under the vehicle and see the wires run into grommets then into somewhere in the vehicle. Where do they go exactly? I dont wanna splice...
  4. Maintenance and Service
    I have read a lot of post about how to unplug the 02 sensor from the pipe, but on my Gen 1 (1998) i couldnt see the other end where the conecctor plug must be. Instead of that, the 02 cables go through a hole on the chassis. Is there a way to acces to the 02 conecctor plug on the gen1?? may be...
  5. Problems & Issues
    Just replaced an 02 sensor because oil got inside the connectors. How does this happen and how can I fix the problem?
  6. Maintenance and Service
    My "check engine" indicator came on suddenly the other day. Manual indicates this has something to do with a fault in the emissions control system. The car is running fine... I went to Autozone and plugged in their diagnostic tool. The error code reads: "P0138 bank 1, sensor 2" and then...
  7. Problems & Issues
    Hi all, Very upset ....I just came back from dealer and they did a diagnosis as my truck wasn't moving when pressing gas and shaking and of course check engine was on. They found that the o2 sensor went bad and cost was 400$ plus labor and diagnosis. Holy cow is this normal that this sensor...
  8. Problems & Issues
    Hello everyone, searching the forums and hopefully want to order the right part. I am pulling code P0131 on my 99 Cr-V. Heated oxygen sensor - bank 1, sensor 1 (HO2S11). I read Denso sensors are better, what is the correct part number for the sensor. Is the 99 a A/F sensor or only O2 sensor...
  9. Problems & Issues
    I got a check engine light on my 2003 CRV-EX (64000) miles. Our friendly neighbourhood mechanic quoted about $400 to change the primary oxygen sensor (a.k.a air fuel ration sensor) using the original Honda part - $350 for the part and $50 for labor. (I'm guessing the dealer might have asked...
  10. Maintenance and Service
    I have about 70k miles on my 2003 crv and started getting check engine lights. I traced it to problems with down stream oxygen sensor in front of cat.converter. so I purchased a universal Bosch oxygen sensor with built in heater rather than custom unit that was 2-3x more expensive. the wiring...
  11. Maintenance and Service
    I have seen a huge difference in the price of oxygen sensors and would like some advice. I have read in most of the forums to stay away from Bosch, but that that Denso are pretty good. Somebody tell me why this sensor is so cheap...
  12. Problems & Issues
    I took my car to my mechanic for an oil change, but the check engine light was on after the oil change. He plugged in his computer to check the code and it is an oxygen air flow problem to the fuel gauge. Does anyone know what that means? I want to get it fixed, but I also want to know what...
  13. Problems & Issues
    Hi, I'm new to the forum but from what I've been reading the answers have been really thorough and helpful. I just learned from my mechanic that my front o2 sensor is showing as failed. I'd like to replace it myself, which he said would definitely be a more economical alternative (he's a...
  14. Maintenance and Service
    My friend has a 2002 Honda CRV and came home from the shop after her check engine light came on, with "service needed" on her bill. It says: "Needs oxygen sensor bank 1 sensor 1, bank 1 sensor 2 $ 468.95." It does not say how much is labor, but that sounds like alot of money. My question is...
  15. Performance Modifications
    Hi, as part of my experimentation with the engine I need to locate the oxygen sensor(s). Can anyone provide a photo for me and tell me how many of them a 1997 (first CRV Honda made) has please. Thank you very much.
  16. Problems & Issues
    Hello everyone. I have a nagging problem with my CRV :( My check engine light was on so I had the code read and it indicated O2 sensor. I replaced both with Densos. The mechanic reset the computer. After a non-specific amount of time the light came on. I took it back and they hooked it up to...
  17. Miscellaneous / General CR-V Discussions
    Hi, I just bought a 1998 CRV Ex. The oxygen sensors and catalytic converter need to be replaced. The front sensor's connector is attached to the car via what looks like a flat metal blade. I cannot get the connector loose from this blade. Is the connector just pressed on or is there some...
