Land Rover Discovery 3 2010-2011 Stoichiometry Sensor LR014011 OEM Standard

Land Rover Discovery 3 (2010-2011) air-fuel ratio sensor LR014011, compatible with LR014012 and AH229G444CA, directly replaces OEM parts with broad compatibility. Core function: monitor exhaust oxygen content and feed ECU to adjust injection to maintain optimal air-fuel ratio. After installation, idle stability improves, acceleration strengthens, and fuel economy and emissions reliability improve. If cold-start is difficult, fuel consumption rises, or engine vibration occurs, sensor aging is usually the cause.
