This 4-wire, direct-fit, narrow-band sensor sits in the downstream position and gives the ECU the diagnostic feedback its application requires.

• Monitors exhaust gases to help reduce pollutants
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes with a gas-permeable platinum layer
• Oxygen readings used to monitor the air-fuel ratio and fine-tune the air-fuel mixture for fuel economy
