Review on 🚀 Enhance Fuel Efficiency with Denso 234-4512 Oxygen Sensor by Anthony Cayton

On my 2007 sienna the check engine icon comes on and the trac off and vsc come on. Using the ODB2 reader, checked for trouble code P0037 HO2S Heater Control Circuit Low. Somewhere on the net I found that this product is the right replacement for the post-catalyst heated oxygen sensor. Good news: it works. After replacing the old sensor with this one and resetting the trouble code, the "Check Engine" light is no longer illuminated. was also not present in the original sensor. I had to hide the clip and extra cable behind the firewall.
