Bosch 15048 oxygen sensor for the 1997-1999 Jaguar XK8 V8 4.0L and other vehicles tells the ECU how rich or lean the engine is running. It is an upstream sensor, a Bosch premium oxygen sensor that helps the ECU hold combustion steady and keep emissions down.
- Heated narrow-band switching-type design with an integrated heater element
- Reaches operating temperature in under 10 seconds for quick closed-loop control
- Metal housing and TSP coating resist vibration, corrosion and contamination
- Withstands exhaust streams up to 1,880 °F
- Part of the Bosch Switching-Type Oxygen (O2) Sensors line
Quick facts
- Part: Bosch 15048 oxygen sensor
- Fits: 1997-1999 Jaguar XK8 V8 4.0L and other vehicles
- Position: Upstream
- Material: Metal housing
- Condition: New
A worn upstream sensor can show up as a check engine light, a rough idle or poorer fuel economy. Those signs alone do not prove the sensor is at fault, since an exhaust leak near it can throw off the reading too. If the sensor is the cause, this one replaces it.
Fits
This sensor is a direct-fit replacement for several Jaguar models, led by the 1997-1999 Jaguar XK8 V8 4.0L, the 1998-1999 Jaguar XJR V8 4.0L and the 1998 Jaguar Vanden Plas V8 4.0L.
