Thread: 2003 Honda CRV CEL ON - Codes P1166

    Default 2003 Honda CRV CEL ON - Codes P1166

    Hello All,

    I had googled the problem code P1166 for my honda CRV 2003. Apparently, P1166 is the primary O2 Sensor failure. There are two O2 sensors (Front & Rear) for 2003 Honda CRV. How do I know which O2 sensor is broken?

    Also, several posts had mentioned that Borsch O2 sensor is not compatible with Honda CRV. Some recommended that Denso O2 sensor is the way to go, which I can get from Autozone for around $200++. I couldn't find the exact part number for Denso O2 Sensor. Could anyone provide me the exact Denso part number for O2 sensor?

    Appreciate it. Thanks

    Primary sensor is the 1st (front) sensor.

    Search these forums and find the threads about members who have paid WAY LESS for the same sensors. Don't put silicone grease or silicone glue near them. They die from that.

    Try 'ebay sensor(s)' for your search keywords.

    This site has the Denso front O2 sensor for a 2003 CR-V for $177.

    http://densoproducts.com

    The Autozone.com website lists it for $199.

    Thanks everyone for the prompt responses.

    After looking into the Denso Oxygen Sensor, the http://densoproducts.com provided me the part number: 234-9005 ($177) for 2003 Honda CRV. From Amazon.com, I can find Denso Oxygen Sensor (P/N:234-9005) for $150 but Amazon said that Denso Oxygen Sensor (P/N234-9005) does not fit my 2003 Honda CRV. The correct Denso Oxygen Sensor part number should be P/N:234-9040.

    Does anyone ever install a Denso Oxygen Sensor on their CRV? Do you recall what is the exact Denso Oxygen Sensor part number?

    Thanks

    Posticon Crv More on O2 sensors and P1167

    I too had a p1167 code I pulled the forward No1 sensor (2003 crv EX with 52k miles) The markings on the pulled part are
    DU2
    DENSO
    192400-1101
    09D25

    None of the vendors seem to recognize these numbers
    I tried densoproducts.com They say the correct p/n is 234-9005
    Carquest same
    Honda dealer and Bernardi say the Honda p/n is 36531-PPA-305

    It looks like the price will be close to $200 so before I commit the cash can anyone help confirm the right p/n and explain why the denso number from the part I pulled does not show up in current catalogs?

    the numbers on the part itself probably are not part numbers... they are probably production stamps saying when it was made, where it was made, who it was made for, etc...

    i guarantee you the honda part number will fit... (probably the same exact part as the Denso part number) but i dont know which denso part number it corresponds with... i would probably trust the denso website tho, since it's their product, they should know what they are talking about more than some amazon seller...

    Did you use our search engine to find the other member's thread? He paid well under $100 each, but I think he had to re-splice the connector. Not a hard job since the thing is already out of the vehicle....

    There were a couple of people who bought sensors from eBay and paid a fairly cheap price. They are Denso O2 sensors, but do not have the connector prewired, so you'd have to splice the connector from the old O2 sensor onto the wires from the new sensor.

    I found this listing...

    NEW DENSO OEM OXYGEN SENSOR 1997-2004 HONDA CR-V

    Good Luck.
