Review on Denso-234-4368: High-Quality Black 🔌 Oxygen Sensor for Optimal Performance by Douglas Cochrane

Start at the top. Video available on YouTube. Release the 2 latches to release the wire harness and disconnect the connector. Tie a wire to the sensor connector. Disconnect the clip holding the wire harness to the bracket halfway up. Unscrew the sensor, which can be difficult depending on the tools available. Since you tested the resistance of the sensor heater (2 black wires) and got infinite ohms, you can cut the wires and use a 22mm or 7/8" socket wrench. Screw in the new sensor and tighten with the open end. Pull down the cut wires and use the rope to fish out the new ones. I use Denso on Asian cars when available, Bosch and AC Delco when not.
