They will resemble golden or brass pegs with wires coming out of the tips.2. Unplug the sensor's wires from where they connect to the Tundra's electrical system.
When an Oxygen sensor goes damaging, it Testament doer an imbalance in the fuel/air ratio, which in turn can agency your Motor lorry to spew away a doozer dimensions of harmful emissions. Whether you're nearing the bit of your succeeding smog check, this can be a huge problem. Fortunately, O2 sensors are not difficult or particularly expensive to replace.

5. Screw the new O2 sensor back into the O2 sensor hole and tighten it down securely. Connect the trailing wires back to the electrical socket you removed your old O2 sensor's wires from.
