      Replaced 2003 Toyota 4Runner OEM sensor because VSC & Engine Light came on. The error code P0031 displayed on the code reader. After installing the new oxygen sensor, the VSC & Engine Light turned off automatically. You may NOT have to recalibrate the "zero Point" settings, so be aware/save you some time. NOTE: After installing the new sensor, the heat from the exhaust will burn the anti-seize compound causing it to smoke and smell a little. It's normal and will go away. 🙂

      Direct fit for a Lexus GX470. Got a shop to read my Check Engine Light Code for free. It pointed to P0031 which was Bank 1 Sensor 1 or Top Left Pre Catalytic converter. Bank 1 Sensor 2 is post cat. Bank 2 Sensor 1 is top right side pre cat and Bank 2 sensor 2 is right post cat or bottom. Find which one it is, unplug the old old, unscrew it, screw in this new one, plug it in. Job Done. That easy. Spend the extra few bucks for the direct fit, that comes with plug. Universal fit isn't worth it, you save a few dollars to crimp the sensor on the old plug. Could be the plug bad too just get the whole unit in one shot.

      The sensor itself is well made. Comes with its own connectors and requires you to cut the oem connector off. Meaning that your stuck using these sensors from there out. I just it the oem style connector off of the sensor I removed and spliced it onto the new sensor.

      Buyer Beware

      Submitted 2020-11-11

      By Kmurfone

      From St. Louis, MO

      I purchased this OEM brand O2 sensor for my 2007 Suburban and it is the downstream sensor. After opening the box, I found that that the sensor doesn't come with a plug but just bare wires with four wire crimp splices and heat shrink sleeve. Had I known this, I wouldn't have purchased this sensor. Later I found out that it is a universal type sensor so that is why it doesn't come with a plug to plug into the vehicle's wire harness. Then I noticed on Advance Auto Parts website, the "Universal" word in the sensor type. In this case, Universal, means that it won't have a plug and you'll have to splice wires together at installation, so buyer beware. I also purchased the Denso upstream sensor from Advance Auto Parts and it is a Direct Fit type which means that it has the plug and requires no wire splicing. I don't understand why Advance Auto Parts doesn't sell the downsteam sensor with the plug on the wires.

      For Scion/Toyota splice the sensor's two black wires to the two white Scion plug wires. It doesn't matter which of the two are connected since polarity is not an issue for the heat element. With two wires left to splice we have a 50% chance for success. lol The sensor ground wire is white and Scion/toyota use color gray for grounds. connect white to gray leaving the sensor sending wire blue to be connected to the Scion/Toyota black wire from the plug. The result should be no check engine light and a better running fuel mixture. Thanks and good luck

  • First Time Fit Oxygen Sensor

    Denso - First Time Fit Oxygen Sensor (Part No. C5010305032ND)

    Description
    Denso First Time Fit oxygen sensors are constructed of the highest quality materials available. High-quality stainless steel, porous polytetrafluoroethylene (PTFE), fluorine rubber, aluminum oxide, high-grade platinum and ceramics are used in each DENSO sensor.

    Product Features:
    • SUPERIOR DESIGN - Maximizes engine performance and fuel efficiency while reducing harmful emissions.
    • DOUBLE-PROTECTION COVER - Maintains proper unit temperature for quicker response times and protects the ceramic element against silicone and lead poisoning.
    • ALUMINUM-OXIDE TRAP LAYER - Keeps silicone and lead outside the ceramic element through DENSO's exclusive design, preventing damage to the platinum electrode.
    • STAINLESS STEEL HOUSING - Resists corrosion and contamination with a rugged, watertight body.
    • POROUS PTFE FILTER - Allows atmospheric oxygen to enter the sensor without permitting water or engine contaminants to seep into the casing. Denso First Time Fit oxygen sensors are coated with a special formulation of aluminum oxide to trap impurities outside of the ceramic element. In head-to-head testing against the leading competitors, DENSO oxygen sensors were rated two times more resistant to silicone and lead poisoning. Installation Notes: Vehicles equipped with Air Fuel Ratio Sensors may look very similar to the Oxygen Sensor. Please confirm the correct part before ordering and if the connector does not match, do not install. Recommended Installation Tool - 234-0100, O2 Sensor Socket Set
