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!

both are colour coded so you cant get them mixed up. Its looking like a sensor problem cleaned terminals up re connected but the fault is still there
