Bosch 15634 oxygen sensor for the 2002-2006 Suzuki XL-7 V6 2.7L and other vehicles reads the oxygen in the exhaust and sends air-fuel-ratio measurements to the ECU. This upstream sensor is a heated, narrow-band switching type that helps the ECU hold stable combustion control and keep emissions down.
- Reaches operating temperature in under 10 seconds, so the ECU gets a signal quickly for closed-loop control
- Metal housing with an integrated heater element and TSP coating to resist vibration, corrosion and contamination
- Withstands exhaust gas temperatures up to 1,880°F
- Advanced ceramic element and optimized heater control for consistent output under thermal and vibration loads
