Welcome back Dennis,

Change of vehicle .....?

I'm pretty sure the I-Pace doesn't have an oxygen sensor. Is this for your XK8? If so I'll move this to the right forum.

 

That code is for the upstream O2 sensor, bank 1 (so UK driver side). You can check the basics (fuse, relay), but the sensor likely needs to be replaced. It's doable from the top. It is near the top of the vertical section of the cat converter, and the end of the exhaust manifold, by the firewall. Not too hard to reach. A crows-foot O2 sensor tool worked great for me. Follow the wiring to a post behind the throttle body. Be sure to replace this sensor with a proper wideband sensor, upstream and downstream sensors are not interchangeable.

Best of luck, keep us posted.
