Review on 🔌 Denso 234-4209 Oxygen Sensor with Connectors (not included) by Steve Yang

This is a really inexpensive way to replace an OEM Denso sensor if you don't mind splicing the wires and waterproofing the connectors. I cut the wires on my stock O2 sensor so the connection point is inside the car. I used these amazing 50 pack heat shrink butt connectors from DEPEPE. Waterproof solder connectors 22-18 AWG red shrink butt connectors from DEPEPE that I had lying around after installing the stereo. The new O2 sensor works great (according to my OBD-II scanner) and reads the output in the OBD-Fusion app. Veepeak OBDCheck BLE Bluetooth 4.0 OBD2 Scanner Car Diagnostic Tool for iOS Android Auto Check Engine Light Fault Code Reader Support 1996 and Newer US Vehicles
