Steve,

P1647 : ECU HO2 Sensor control malfunction - bank 2 upstream

Other than a circuit fault, I'd think it's likely to be a duff Sensor.

Steve,

The description 'just unscrew' hasn't applied to the last few Sensors I've removed. They were b****y tight!

It will be.

If the X-Type is similar to the XJ and XK, the wires aren't set to a specific sensor. They are wired up first and then configured using the dealer WDS. Just in case, don't get them mixed up!
