Walker Products 250-25068 oxygen sensor for the 2010-2011 Mazda CX-7 4-cylinder 2.5L sends the ECU feedback on the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a wide-band unit made for its specific application and fitment position.
- 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
- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Monitors the air-fuel ratio for combustion efficiency
Quick facts
- Part: Walker Products 250-25068 oxygen sensor
- Fits: 2010-2011 Mazda CX-7 4-cylinder 2.5L
- Position: Upstream
- Condition: New
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, wiring harness and connector for physical damage with the engine off and cool, because a damaged harness or connector can mimic a bad sensor.

Frequently Asked Questions
Does the Walker Products 250-25068 fit the 2010-2011 Mazda CX-7 4-cylinder 2.5L?
Yes. Walker Products 250-25068 is an upstream oxygen sensor for the 2010-2011 Mazda CX-7 4-cylinder 2.5L, and that engine takes one.
Is this a wide-band oxygen sensor?
Yes. Walker Products 250-25068 is a wide-band sensor, and its electrodes are made of a gas-permeable platinum layer.
What thread size does this oxygen sensor have?
This oxygen sensor has an M18 - 1.5 thread.
What can a failing upstream oxygen sensor cause?
The engine can run poorly, use more fuel, put out more emissions or turn on the malfunction indicator light. Stored ECU fault codes may also relate to the sensor and its systems.
What protects the electrodes on this oxygen sensor?
A coating shields the electrode surfaces from contamination and erosion caused by combustion residue and particulates in the exhaust gases.
