Walker Products 350-34568 oxygen sensor for the 1994-1995 Cadillac DeVille V8 4.6L or 4.9L and other vehicles reads the oxygen content of the exhaust gas to monitor combustion efficiency. This Walker Products oxygen sensor is a narrow-band, 4-wire, direct-fit unit.
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel mixture
- Monitors exhaust gases and helps reduce pollutants
- Electrodes made with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Each part number is made for one specific application and fitment position, with the diagnostic feedback the ECU requires

A failed sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. These signs can point to a worn oxygen sensor, though its wiring harness or connector can also be behind them, so inspect all three for physical damage before you replace the sensor.
Fits
It is listed for a wide range of Cadillac and Oldsmobile models, including the 1993-1995 Cadillac Eldorado V8 4.6L and the 1993-1995 Cadillac Seville V8 4.6L. If your car is not one of these, look it up by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this Cadillac DeVille oxygen sensor right for the 1994-1995 model with a V8 4.6L or 4.9L?
Yes. Walker Products 350-34568 is listed for the 1994-1995 Cadillac DeVille V8 4.6L and V8 4.9L, with a quantity of one per vehicle.
What type of oxygen sensor is the Walker Products 350-34568, and what thread does it have?
This oxygen sensor is a 4-wire narrow-band unit with an M18 - 1.5 thread, and it is a direct fit.
What is the coating on this oxygen sensor for?
The coating keeps combustion residue and particulates in the exhaust gases from contaminating or eroding the electrode surfaces. The electrodes themselves have a gas-permeable platinum layer.
Will a failing oxygen sensor store a fault code?
Newer vehicles can store fault codes in the ECU, and some relate to the affected sensor and its systems. The malfunction indicator light can also come on.
Which position does the Walker Products 350-34568 oxygen sensor go in?
Walker Products 350-34568 is catalogued as an upstream oxygen sensor, with upstream left, right, rear and front positions also listed. Every part number is made for its specific application and fitment position.
