Believe sensor is not the correct upstream sensor for the car. Ordered and installed different sensor and it worked fine.

I always use Denso. Absolute quality. Perfect Fit for my 2006 Scion XB. You will need a 22MM socket to install it. It already comes with Anti-seize installed !! Replacing both the front and rear O2 sensor my car now gets 3.56 mpg better per gallon of gas.

The easiest o2 install I have ever done. The hardest part was disconnecting the plug and it wasn't difficult. Original toyota stamped o2 sensor came out of an 06 with 190k miles. I don't expect it to last that long but cheaper than autozone and an easy job. Downstream was not changed wires are tucked away so take a look first if you're going to do it.

Excellent product, Fixed 2 codes on a 2006 Scion XA. Codes P0133 and P0134.I replaced both oxygen sensors on the vehicle with parts, DENSO 2344524 (upstream) and DENSO 2344069 (downstream)It is very easy to replace. It was probably more work to raise the vehicle off the ground with enough clearance to get underneath and work.Before the replacements, the car ran sluggish and consumed way too much fuel.. After the replacements, it runs at ease and consumes little to no fuel for a 60 mile trip and codes are now gone.

Had the check engine, track off, vsc light. Ran OBD scan and received codes P0456, P0442, P0456 MIL ON MONITRS 0 INC 7 READY MISFIRE FUEL Comp Catlyst Evap O2 Snsr O2 Htr. Replaced O2 sensor with this item on my 2004 Scion XB and the lights went off and no codes.It was a royal pain to remove it, so make sure to brush off any rust with a wire brush and use WD40. Heat up and cool down several times to loosen. Make sure to use threaded socket as it will be night and day without this tool.This item also includes Nickel Anti-Seize Lubricant, so no need to buy any.
