The DENSO Oxygen Sensor 234-4794 is a heated, narrow-band, direct-fit sensor. It reads exhaust oxygen content downstream of the catalytic converter so the engine computer can monitor how the converter is operating.
It fits many vehicles, among them the 2014-2024 Jaguar F-Type 3.0L / 5.0L, 2013-2020 Jaguar XF 3.0L / 5.0L and 2014-2020 Land Rover Range Rover Sport 3.0L / 5.0L. Listed applications include V6-3.0L, V8-5.0L and L6-3.0L engines. Depending on the application, it is cataloged as the downstream, downstream left or downstream right sensor. This listing is for one sensor, and the listed applications use one or two.
- Protected sensing element: A laser welded stainless housing resists corrosion, and a PTFE filter blocks contaminants under harsh engine conditions. Dual-layer protection shields the ceramic element and is designed to support fast, reliable response times.
- Aluminum oxide trap layer: DENSO's exclusive trap layer is designed to protect the ceramic element from silicone and lead poisoning.
- Built and tested to OE standards: DENSO manufactures and tests its oxygen sensors to strict OE standards. Each component is precision built for exact replacement and a first-time fit.
- Specifications: Heated, narrow-band, 4 wires, male connector, 0.708 in thread diameter, 12.01 in wiring harness, threaded mounting, specific fit.
Signs a downstream oxygen sensor may need replacing include a check engine light with oxygen sensor codes, or a sensor signal that reads slow or erratic. If a failed sensor is the cause, this unit replaces it. Diagnose the fault first, because other problems can set similar codes.
