Review on Denso 234 9049 Air Fuel Sensor by Roberto Evans

Got code P0051 heated O2 sensor bank 2 sensor 1 code on a 2008 Toyota Sienna 3.5L LE and called another I think C1201 or something. However, I only got P0051 at first so I figured that was the main culprit and read online that the code would set off a different code due to the networked system. I am going to replace the original Toyota part number 89467-08050 Denso 1190 01K03 with this one (Denso 234-9049) and all the Check Engineer, Track Off and VSC lights are off. I lubricated a PB catalytic converter in the morning, drove the van all day and relubricated it at night and was able to replace the old sensor in 5 minutes using a TEKTON 4929 3/8" drive with a 7/8" Drive remove socket for oxygen sensor. Be sure to apply the anti-seize compound that came with the sensor. The sensor I changed is on the front right. When you open the hood, it says left (as if you were driving). The dealer asked $225 and it was a special order for parts and labor only, probably a similar amount so he saved about $400. They are called air to fuel ratio sensors and they have 4 wires. Hope this detail helps someone and saves $$$
