Front Oxygen Sensor for 1996-1997 Mazda 626 & More - Walker 350-33027

Walker Products 350-33027 front oxygen sensor for the 1996-1997 Mazda 626 4-cylinder 2.0L or V6 2.5L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. It is a narrow-band sensor.

• Monitors exhaust gases and reduces pollutants for a cleaner environment
• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
• Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
• Electrodes made of a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Made for its specific application and position, with the diagnostic feedback the ECU requires

Quick facts

• Part: Walker Products 350-33027 oxygen sensor
• Fits: 1996-1997 Mazda 626 4-cylinder 2.0L or V6 2.5L and other vehicles
• Position: Front, upstream
• Condition: New

A failing oxygen sensor might show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a vacuum leak can cause some of them too.

Fits

This is a direct-fit replacement for the 1996-1997 Mazda 626 and the 1996-1997 Mazda MX-6, both with the 4-cylinder 2.0L or V6 2.5L, and an oxygen sensor for the 1996-1997 Ford Probe V6 2.5L. Each calls for a single sensor, and this listing is one sensor.
