Womala Rear Oxygen Sensor LR098290 for Land Rover Range Rover

Product Overview

The Rear Oxygen Sensor LR098290 is an OE-grade emissions control component for for Land Rover vehicles with 3.0L V6 and 5.0L V8 petrol engines. Also known as a downstream O₂ sensor or lambda sensor, it monitors oxygen levels in the exhaust stream after the catalytic converter, providing feedback to the ECU for precise air-fuel ratio adjustment. LR136928 is the current replacement part, superseding LR098290 and LR035748. 

Key Features

• Rear/downstream (post-catalyst) position – fits left and right rear positions 

• Heated 4-wire sensor – reaches operating temperature quickly for accurate readings 

• OE-grade quality – genuine Land Rover specification

• Plug-and-play installation – direct-fit replacement with factory connector

• For 3.0L V6 & 5.0L V8 petrol engines – AJ126 / AJ133 engine families 

OE Cross-Reference

Vehicle Fitment

Engine details (verify with VIN):

• 3.0L DOHC GDI SC V6 Petrol (AJ126)

• 5.0L OHC SGDI NA V8 Petrol (AJ133)

• 5.0L OHC SGDI SC V8 Petrol (AJ133) 

⚠️ Important: This sensor is specifically for petrol/gasoline engines – 3.0L V6 and 5.0L V8. Not for diesel, 2.0L Ingenium, or other engine variants. Fitment varies by model year, production date, and VIN range – verify before ordering.

Signs of Failure

• Check engine light – O₂ sensor-related DTCs

• Poor fuel economy – decreased MPG due to incorrect air-fuel mixture 

• Failed emissions test – elevated emissions output

• Loss of power – reduced engine performance 

💡 O2 sensors are one of the more commonly failed sensors in a Land Rover emissions control system. Continuous exposure to exhaust temperatures ranging from 300°–700°F over time causes the sensor element to lose its ability to create voltage, making the sensor give incorrect readings. 

Critical – Verify Your VIN Before Ordering

Oxygen sensors are VIN‑, engine‑, and position‑specific. Variations in engine type (3.0L vs. 5.0L petrol), production date, and VIN range affect fitment. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. Allow the engine to cool before replacement. Apply anti-seize compound to threads (avoiding sensor tip) and torque to specification. Replace in pairs for balanced performance.
