Walker Products 350-34413 oxygen sensor for the 2005-2006 Cadillac XLR V8 4.6L measures the oxygen in the exhaust gas to gauge combustion efficiency. This Walker Products oxygen sensor is a 4-wire, narrow-band direct-fit unit.
A failing sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind the same signs, so find the cause before you buy a sensor.
This direct-fit sensor is for the 2005-2006 Cadillac XLR V8 4.6L, which takes one; this listing is one sensor.
Fit and size
Build and materials
Is the Walker Products 350-34413 oxygen sensor right for the 2005-2006 Cadillac XLR V8 4.6L?
Yes. Walker Products 350-34413 is a direct-fit narrow-band sensor for the 2005-2006 Cadillac XLR V8 4.6L, and that car takes one.
Is this oxygen sensor wideband or narrow-band?
It is narrow-band. The Walker Products 350-34413 has four wires and is a direct-fit narrow-band unit.
Is this a downstream oxygen sensor?
Yes. This sensor is for the downstream left and downstream right positions.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. A coating on them keeps combustion residue and exhaust particulates from contaminating or eroding the electrode surfaces.
Can a bad oxygen sensor hurt fuel economy?
Yes, a failed sensor can make the engine run poorly and increase fuel consumption or exhaust emissions. Newer vehicles store fault codes, which a shop can read.
