Oxygen Sensor for 2004-2005 Suzuki Forenza & More - Walker 350-34688

Walker Products 350-34688 oxygen sensor for the 2004-2005 Suzuki Forenza 4-cylinder 2.0L and other vehicles measures exhaust-gas oxygen to show combustion efficiency. This Walker Products oxygen sensor is a 4-wire, narrow-band, direct-fit unit.

• Monitors exhaust gases and helps reduce pollutants
• Determines the oxygen content of the exhaust gas and monitors the air fuel ratio for combustion efficiency
• Electrodes carry a gas-permeable platinum layer
• Platinum layer protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Made for its specific application and sensor position, giving the ECU the diagnostic feedback it needs

Quick facts

• Part: Walker Products 350-34688 oxygen sensor
• Fits: 2004-2005 Suzuki Forenza 4-cylinder 2.0L and other vehicles
• Position: Upstream, downstream
• Condition: New

Poor running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can mean the sensor is worn, though a damaged wiring harness or connector can be behind the same signs, so look all three over for physical damage. Its oxygen readings help fine-tune the air-fuel mixture for fuel economy. This listing is one sensor, and each listed application takes one in the position it is built for.

Fits

As a direct-fit narrow-band oxygen sensor, it also goes on the 2005 Suzuki Reno 4-cylinder 2.0L and the 2001-2003 Mazda Protege 4-cylinder 2.0L.
