Jaguar XJ 2005-2007 Front Oxygen Sensor C2C29250 Original Position Direct Plug Replacement

When your Jaguar XJ (2005-2007) displays the engine fault light, idle instability, weak acceleration, or noticeably higher fuel consumption, this usually indicates the pre-cat oxygen sensor has aged or failed and cannot accurately monitor oxygen content. When functioning normally, the sensor feeds real-time air-fuel ratio signals to the ECU to help maintain optimal burn efficiency, boosting power and reducing emissions. This product with OEM number C2C29250 fits Jaguar XJ 2005-2007; factory direct plug-in design requires no harness modification. During installation, ensure sensor threads are clean and apply anti-seize to prevent over-tightening and thread damage, also avoid wiring harness contact with high-temperature exhaust areas.
