Walker Products 250-24380 oxygen sensor for the 1994-1995 BMW 530i V8 3.0L and other vehicles measures exhaust-gas oxygen to show combustion efficiency. It is made for a specific application and position and sends the ECU the diagnostic feedback it needs.
- Narrow-band sensor with 4 wires
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Coating on the electrodes resists contamination and erosion from combustion residue and particulates in the exhaust
- Electrodes with a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24380 oxygen sensor
- Fits: 1994-1995 BMW 530i V8 3.0L and other vehicles
- Position: Upstream left, upstream right
- Condition: New
A failing sensor can show up as a poorly running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. The wiring harness and the connector can be behind those signs as well, so look both over for physical damage before replacing the sensor.
Fits
This direct-fit oxygen sensor fits the 1994-1995 BMW 530i V8 3.0L, the 1995 BMW 740i V8 4.0L and the 1995 BMW 740iL V8 4.0L. This listing is one sensor, and each upstream position, left and right, takes one. If your BMW is not named here, look it up in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 1994-1995 BMW 530i V8 3.0L?
Yes. Walker Products 250-24380 fits the 1994-1995 BMW 530i V8 3.0L and is listed for the upstream left and upstream right positions.
Will this oxygen sensor fit the 1995 BMW 740i V8 4.0L?
Yes, it fits the 1995 BMW 740i V8 4.0L, in the upstream left or upstream right position.
Does this Walker Products oxygen sensor use a narrow-band design?
Yes. Walker Products 250-24380 is a 4-wire narrow-band oxygen sensor with electrodes made of a gas-permeable platinum layer.
Can a failing oxygen sensor turn on the malfunction indicator light?
Yes, a failed oxygen sensor can light the malfunction indicator light. It can also make the engine run poorly or raise fuel consumption and exhaust emissions, and newer vehicles store fault codes in the ECU that a shop can read.
Is this oxygen sensor an upstream or downstream unit?
Upstream. This sensor is listed for the upstream left and upstream right positions, and each of those positions takes one.
