Walker Products 350-34347 oxygen sensor for the 2002-2003 Suzuki Aerio 4-cylinder 2.0L, the 2004-2007 Aerio 4-cylinder 2.3L and other vehicles measures combustion efficiency from the amount of oxygen in the exhaust gas. It is a 4-wire, narrow-band, direct-fit sensor for the upstream position.
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
- Monitors exhaust gases and helps reduce pollutants for a cleaner environment
- Electrodes made of a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Measures oxygen levels to fine-tune the air-fuel mixture, which helps fuel economy
- Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases
Quick facts
- Part: Walker Products 350-34347 oxygen sensor
- Fits: the 2002-2003 Suzuki Aerio 4-cylinder 2.0L, the 2004-2007 Aerio 4-cylinder 2.3L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or switch on the malfunction indicator light. Those signs alone do not prove the sensor is at fault, because a vacuum leak can produce them too. Inspect the wiring harness and connector for physical damage as well.
Fits
The 2002-2003 Suzuki Aerio 4-cylinder 2.0L, the 2004-2007 Aerio 4-cylinder 2.3L, the 2001-2005 Suzuki Grand Vitara V6 2.5L and the 2001-2004 Chevrolet Tracker V6 2.5L are among the vehicles this oxygen sensor fits.
