Land Rover Range Rover/Discovery 2012- Rear Oxygen Sensor LR013661

Range Rover / Discovery series 2012 onward upstream oxygen sensor LR013661, direct replacement of the original OEM number, no wiring harness or bracket adjustment required. It monitors exhaust after the catalytic converter; ECU uses this to calibrate the reference value of the upstream oxygen sensor. Fits models with 3.0L diesel or 5.0L gasoline engines; installation torque recommended 40-50 N·m. If vehicle displays unexpected fuel consumption increase, louder exhaust noise on acceleration, or emission warning light, indicates sensor can no longer provide accurate voltage; timely replacement prevents catalyst damage.
