Parts Needed:
- New O2 Sensor (OEM replacement part is recommended: C2S28296)
- Splice connector
- Multimeter
- Socket wrench set
- Jack and jack stands
- Safety glasses
Instructions:
1. Prepare your vehicle. Park your car on a level surface, apply the parking brake, and turn off the engine. Allow the engine to cool down if it has been running. Engage the gear stick into first gear for manual transmission models, or into park (P) for automatic transmission models. Engage the parking brake and shut off the engine. Engage the parking brake and shut off the engine. Raise the front of the vehicle using a jack and place it on jack stands for access to the catalytic converters and the O2 sensors.
2. Locate the oxygen sensor. The oxygen sensor on the 2002 Jaguar X-Type is located on the exhaust manifold, near the engine's cylinder head. There are three O2 sensors in total: one mounted before the catalytic converter (bank 1 sensor 1) and two mounted after the catalytic converters (bank 1, sensor 2 and bank 2, sensor 1). You'll need to identify which sensor you'll need to replace and disconnect it accordingly.
3. Disconnect the oxygen sensor. First, disconnect the electrical connector from the oxygen sensor. Then, use a wrench to loosen and remove the sensor from the exhaust manifold. Be careful not to drop the oxygen sensor or get burned by the hot exhaust manifold.
4. Install the new oxygen sensor. Screw in the new oxygen sensor by hand until it is snug. Then, use a wrench to tighten the sensor to the specified torque.
5. Reconnect the electrical connector. Reconnect the electrical connector to the oxygen sensor.
6. Test the oxygen sensor. Start the engine and let it run for a few minutes. Then, use a multimeter to check the voltage output of the oxygen sensor. The voltage should fluctuate between 0 and 1 volt.
7. Clear trouble codes. If you have a check engine light on, you may need to clear the trouble codes from your on-board computer. This can be done using a scan tool.
8. Reassemble everything. Lower the car and remove the jack stands. Be careful not to drop the oxygen sensor wires.
Your oxygen sensor is now replaced.
