The oxygen sensor installs in the upstream position on select 2018-2025 Jaguar and Land Rover applications. It measures the exhaust air-fuel ratio across a broad range so the engine computer can meter fuel precisely. A built-in heater brings the element to operating temperature quickly after a cold start.
