Walker Products 350-34332 oxygen sensor for the 1996-1999 Saturn SC1 4-cylinder 1.9L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a 4-wire, direct-fit narrow-band unit for the downstream position.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34332 oxygen sensor
- Fits: 1996-1999 Saturn SC1 4-cylinder 1.9L and other vehicles
- Position: Downstream
- Condition: New
The sensor is built for its specific application and fitment position, and it returns the diagnostic feedback the ECU needs. A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace it, look over the sensor's wiring harness and connector for physical damage with the engine off and cool, because a fault there is a separate repair.
Fits
Fits include the 1996-1999 Saturn SC2 4-cylinder 1.9L and the 1996-1999 Saturn SL 4-cylinder 1.9L. If your Saturn is not named here, look up its year and model in the "Vehicles it fits" section. This listing is one sensor, and the 1996-1999 Saturn SC1 4-cylinder 1.9L takes one.

Frequently Asked Questions
Is this the right oxygen sensor for a 1996-1999 Saturn SL 4-cylinder 1.9L?
Yes. Walker Products 350-34332 is a downstream oxygen sensor that fits the 1996-1999 Saturn SL 4-cylinder 1.9L, which takes one. For other Saturns, use the "Vehicles it fits" section.
Is the Walker Products 350-34332 a narrow-band or wideband sensor?
This Walker Products 350-34332 is a 4-wire, direct-fit narrow-band oxygen sensor for the downstream position.
What is the platinum layer on this oxygen sensor for?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas.
Which problems can a worn downstream oxygen sensor cause?
A failed sensor might make the engine run poorly, raise fuel consumption and exhaust emissions, or light the malfunction indicator light. Newer vehicles also store fault codes in the ECU.
Is the 350-34332 sold as a single sensor?
Yes. Walker Products 350-34332 is sold as one downstream oxygen sensor, and the fitment calls for one per vehicle.
