This upstream oxygen sensor is a direct replacement for OEM part number C2P16396. It is a heated, 4-wire wideband oxygen sensor mounted in the exhaust manifold before the catalytic converter (upstream position). It measures the oxygen content in the exhaust gas and sends feedback to the engine control unit to optimize the air-fuel ratio for performance and emissions. Manufactured to OEM specifications, this sensor is designed for Jaguar XF (X250), XJ (X351), and XK/XKR (X150) models equipped with the 5.0L V8 engine, including supercharged variants. Note: this is a heated oxygen sensor, not a “before heating” sensor. Some catalogs list fitment up to VIN V39426.

Q1: What are the symptoms of a failing upstream oxygen sensor?
A: Common signs include a check engine light with oxygen sensor or fuel trim codes (such as P0130-P0135), reduced fuel economy, rough idle, hesitation during acceleration, and failed emissions testing.
Q2: Is this a genuine Jaguar part?
A: This is a high-quality aftermarket replacement manufactured to OEM specifications. The OEM number C2P16396 is referenced for compatibility identification only.
Q3: Does this sensor fit 4.2L Jaguar models?
A: Available catalog data primarily lists C2P16396 for 5.0L V8 applications across XF, XJ, and XK models. Some listings reference 4.2L fitment (such as 2010 XF Base 4.2L), but this is not consistently confirmed across all sources. Please verify your engine code and original part number before ordering.
