Walker Products 250-54109 oxygen sensor for the 2007-2008 Nissan Altima 4-cylinder 2.5L, the 2008-2010 Altima V6 3.5L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a 4-wire, wide-band air-fuel ratio sensor.
- Measures the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- 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
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Made for its specific application and position on the vehicle, with the diagnostic feedback the ECU requires
