Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Is the code P01647? You replaced the top front sensor on the exhaust? Did you use a Jaguar part?
Ok I have run into a lot of issues with aftermarket sensors. We also need to make sure we do not have a wiring issue to the sensor. We need to inspect the area and harness under the battery to make sure it is not damaged. If you have a digital multimeter we can test the circuit.
Let me know.
Ok this sounds like a defective or just not a fully compliant sensor with the engine ECU. I always recommend using the factory sensors because of this. You could confirm this by swapping the upper sensors front to back and clear the codes to see if they travel. The rear sensor can be a little difficult to remove. I remove the purge valve bracket to give more room in accessing it.
The ECU needs to run the monitor before it will set the dtc and turn the engine light on.
