Denso 234 4524 Oxygen Sensor Ratio Review

A few videos from You Tube. A quick trip to get some tools and save a huge mechanic bill. Has taken care of the check engine light and was about to smoke

Direct replacement for my 2006 Scion XB. I replaced my catalytic converter with a Walker 53613 Ultra Import Converter - not CARB compatible and this sensor bolted right in. Wires were properly lengthened and connector was the same as factory. The check engine light hasn't come on in over a year.

Easiest o2 setup I've ever done. The hardest part was unplugging it, it's not difficult. The original O2 sensor with Toyota stamp came from '06 with 190,000 miles on it. I don't expect it to last that long but it's cheaper than Autozone and easy labor. The downstream hasn't been changed, the cables are hidden, so see if you're going to do that first.

There was an engine check, lane off, sunlight. Did an OBD scan and got codes P0456, P0442, P0456 MIL ON MONITRS 0 INC 7 READY MISFIRE FUEL Comp Catlyst Evap O2 Snsr O2 Htr. Replaced the O2 sensor with this item on my 2004 Scion XB and the light went out and there were no codes. It was very difficult to remove so be sure to brush the rust off with a wire brush and use WD40. Heat and cool several times to release. Be sure to use a threaded bushing as you can do it day or night without this tool…

Excellent product, corrected 2 codes on Scion XA 2006. Codes P0133 and P0134. I replaced both oxygen sensors on the car with DENSO 2344524 (upstream) and DENSO 2344069 (downstream). They are very easy to replace. It was probably more work getting the car off the ground with enough clearance to get under and work. Before the replacement, the car was sluggish and used too much fuel. After the replacement it runs light and uses little to no fuel for a 60 mile ride and the codes are gone now.
