        Perfect fit, but difficult to get to and remove. Added heat to nuts to remove. Have replacements (M8-1.25)ready.
        Great on-line ordering experience. On line discount helped with cost.

        Comments about Denso Air Fuel Sensor - Direct Fit:

        Really didn't specify too many details about installing, regarding whether to grease, unplugging negative battery cable, etc. Oh, and be sure you have some spare nuts, likely won't be able to reuse them.

            Comments about Denso Air Fuel Sensor - Direct Fit:

            I'm impressed at the way Advance Auto manages their online presence along with their retail stores. However I was told that they wouldn't honor any type on warranty on online electonic parts and I am pretty sure that's not 100% accurate. Anyhow, I purchased this part since I needed to pass emissions testing to renew my registration and tag. With a PROMO code this was the lowest price on the internet, but these 'air/fuel ratio sensors' are still very expensive parts that are not option.

                      Hi Joel, glad to assist you! The code P1135 is set when the Engine Control Module (ECM) detects a heated oxygen sensor heater circuit malfunction. Both part# 234-9001 and part# 234-9003 are for upstream for your 2002 Toyota Tundra. The only difference is part# 234-9001 is for automatic transmission and part# 234-9003 is for standard transmission.

                      Part no 234-9001 is for a manual transmission where 234-9002 is for automatic. there must be a difference in pharamiter values. The wire lentgh is according to application and has nothing to do with anything else.
                      If you already installed one of these o2 sensors in the reverse order, can you please respond and explain if you have any abnormalities in performance, drivability, or fuel economy.
