Walker Products Oxygen Sensor P/N:350-31040
Walker Products 350-34567 oxygen sensor for the 1993-1994 Volvo 850 5-cylinder 2.4L measures the oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor is made for its specific application and fitment position, and it sends the ECU the feedback it needs for diagnostics.
A worn sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. The wiring harness and connector can sit behind the same signs, so look them over for physical damage before you replace the sensor.
This oxygen sensor fits the 1993-1994 Volvo 850 5-cylinder 2.4L, which takes one upstream sensor. The listing is a single sensor.
Fit and size
Build and materials
Is this the oxygen sensor for a 1993-1994 Volvo 850 5-cylinder 2.4L?
Yes. Walker Products 350-34567 is an upstream oxygen sensor for the 1993-1994 Volvo 850 5-cylinder 2.4L, and that engine takes one.
Is this a narrow-band oxygen sensor, and what thread does it use?
Yes, this upstream oxygen sensor is a narrow-band type with an M18 - 1.5 thread.
What are the electrodes on this oxygen sensor made of?
The electrodes carry a gas-permeable platinum layer. A coating protects their surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
What signs can point to a failing upstream oxygen sensor?
Rough running, higher fuel consumption or a lit malfunction indicator light can all be signs. A shop can test the sensor to find out.
How does this oxygen sensor work with the air-fuel mixture?
Walker Products 350-34567 measures the oxygen content of the exhaust gas and monitors the air-fuel ratio. That helps fine-tune the mixture and fuel economy.
