Oxygen Sensor for 1999-2002 Ford Explorer & More - Bosch 13117

Bosch 13117 oxygen sensor for the 1999-2001 Ford Explorer V8 5.0L, the 1999-2002 Explorer V6 4.0L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. The ECU uses that reading to help keep combustion stable and emissions down.

• Narrow-band heated switching-type sensor that sends air-fuel-ratio readings to the ECU
• Reaches operating temperature in under 10 seconds for quick closed-loop control
• Metal housing with an integrated heater element and TSP coating resists vibration, corrosion and contamination
• Withstands exhaust streams up to 1,880°F
• Advanced ceramic element and optimized heater control for consistent output under thermal and vibration loads
