Walker Products 350-34135 oxygen sensor for the 1998 Volvo S70 5-cylinder 2.3L or 2.4L and other vehicles reads the oxygen in the exhaust gas so the engine computer can track the air-fuel ratio. This Walker Products oxygen sensor is a 4-wire, narrow-band, direct-fit unit made for its specific application and fitment position.
- Measures exhaust oxygen to monitor the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34135 oxygen sensor
- Fits: the 1998 Volvo S70 5-cylinder 2.3L or 2.4L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Before you replace the sensor, rule out damage to its wiring harness and connector by looking them over with the engine off and cool, since physical damage there can shorten a sensor's life.
Fits
The vehicles it fits include the 1998 Volvo V70 5-cylinder 2.3L or 2.4L and the 1998 Volvo C70 5-cylinder 2.4L, each as a direct-fit oxygen sensor. This listing is one sensor, and the 1998 Volvo S70 5-cylinder 2.3L or 2.4L takes one. If your car is not named here, open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this a V70 oxygen sensor that fits the 1998 Volvo V70 5-cylinder 2.3L or 2.4L?
Yes. Walker Products 350-34135 is listed for the 1998 Volvo V70 with either the 5-cylinder 2.3L or 2.4L engine. For another model, open the "Vehicles it fits" section to check your exact car.
What thread does the Walker Products 350-34135 oxygen sensor have?
Walker Products 350-34135 has an M18 - 1.5 thread. It is a 4-wire, downstream sensor.
Is this oxygen sensor narrow-band or wideband?
This downstream oxygen sensor is narrow-band, with four wires. It measures the oxygen in the exhaust gas so the air-fuel ratio can be monitored.
What are the electrodes in this oxygen sensor made of?
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.
What are the signs of a bad downstream oxygen sensor?
The engine may run poorly, fuel consumption or exhaust emissions may rise, or the malfunction indicator light may come on.
