Walker Products Oxygen Sensor P/N:350-34293
Walker Products 350-34008 oxygen sensor for the 2000 Toyota Tacoma 4-cylinder 2.7L or V6 3.4L measures the oxygen in the exhaust gas. This downstream Walker Products oxygen sensor gives the ECU the diagnostic feedback its position requires.
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace it, rule out physical damage to the sensor, wiring harness and connector, and read any fault codes the ECU has stored, because a damaged wire or another fault can produce these symptoms too.
This downstream oxygen sensor is a direct-fit replacement for the 2000 Toyota Tacoma with the 4-cylinder 2.7L or the V6 3.4L engine. This listing is one sensor, and one goes in this downstream position on either engine.

Will the Walker Products 350-34008 fit the 2000 Toyota Tacoma 4-cylinder 2.7L or V6 3.4L?
Yes. Walker Products 350-34008 is a downstream oxygen sensor for the 2000 Toyota Tacoma with either the 4-cylinder 2.7L or the V6 3.4L engine.
Is the Walker Products 350-34008 an upstream or downstream oxygen sensor?
Downstream. Walker Products 350-34008 is a narrow-band sensor with four wires and a mounting flange.
What are the electrodes on this oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects their surfaces from combustion residue and particulates in the exhaust gases.
What does this oxygen sensor actually measure?
It measures the oxygen content of the exhaust gas, which is used to monitor the air-fuel ratio for combustion efficiency.
Will a failing oxygen sensor store a fault code in the ECU?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. This sensor supplies the diagnostic feedback the ECU requires.
