Oxygen Sensor for 1999-2001 Volvo S80 - Bosch 16198

Bosch 16198 oxygen sensor for the 1999 Volvo S80 6-cylinder 2.9L and the 1999-2001 S80 6-cylinder 2.8L measures oxygen in the exhaust and reports the air-fuel ratio to the ECU. This downstream Bosch O2 sensor is a heated, narrow-band, switching-type unit.

• Ceramic elements and optimized heater control for consistent performance under thermal and vibration loads
• Metal housing with an integrated heater element and TSP coating that resist vibration, corrosion and contamination
• Built to withstand exhaust gas up to 1,880°F
• Reaches operating temperature in under 10 seconds, so the ECU gets a signal quickly for closed-loop control

A failing downstream oxygen sensor can come with a check engine light, rough running or poorer fuel economy, though other faults show up the same way. With the engine off and cool, look over the wiring and connector for cuts, melted insulation or a loose plug, and find the cause before you replace the sensor.
