Walker Products Oxygen Sensor P/N:350-34354
Walker Products 350-34451 oxygen sensor for the 2008-2012 Honda Accord V6 3.5L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. Each part number is made for its application and fitment position, and it supplies the diagnostic feedback the ECU needs.
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace the sensor, look its wiring harness and connector over for physical damage, since damage there can look the same from the driver's seat.
This direct-fit oxygen sensor fits the 2008-2012 Honda Accord V6 3.5L. It is also an oxygen sensor for the 2017-2020 Acura MDX V6 3.0L.
Fit and size
Build and materials
One oxygen sensor. The fitment calls for one per vehicle.
I need an oxygen sensor for the 2008-2012 Honda Accord V6 3.5L; is this the one?
Yes. Walker Products 350-34451 is a direct-fit oxygen sensor for the 2008-2012 Honda Accord V6 3.5L, made for the downstream front and downstream rear positions.
What thread and wire count does this Walker Products oxygen sensor have?
Walker Products 350-34451 is a narrow-band sensor with 4 wires and an M18 - 1.5 thread.
How can I tell if a downstream oxygen sensor is failing?
It can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A shop can read the stored fault codes to narrow it down.
What does the platinum layer on this oxygen sensor do?
The sensor's electrodes are made of a gas-permeable platinum layer. That layer keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
Does the Walker Products 350-34451 sensor reduce emissions?
Yes, it helps. Walker Products 350-34451 monitors the exhaust gases to help reduce pollutants, and its oxygen readings help fine-tune the air-fuel mixture.
