According to my Jaguar DTC Summary for the X-type, P1647 is Bank 2 Upstream.

Here's a link to the JTIS X-Type Electronic Engine Controls PDF on my MediaFire account:

Free Cloud Storage - MediaFire

Page 5 illustrates the exhaust layout with the position of two H2OS heated Oxygen Sensors and two Catalyst Monitor Sensors.

The full document provides a useful explanation of all the monitoring components.

Hi Graham,
Thanks for the advice. Here’s the reading for my scanner... Can I assume that I should be getting readings from all four sensors?
02 Bank 1 Sensor 1 no date
02 Bank 1 Sensor 2 low switch 0.050 high switch 0.950
02 Bank 2 Sensor 1 no date
02 Bank 2 Sensor 2 low switch 0.050 high switch 0.950
Regards,
Ps Still geting two codes P1647 P1642

 

According to the JTIS summary, you only have one H2OS sensor in each bank. The other sensor in each bank is a Catalyst Monitoring Sensor. This is why you are only getting two H2OS readings reported.

I would suspect the accuracy of your scanner. If P1642 is reported, it is always accompanied by an additional code identifying the specific module at fault and this doesn't seem to be the case? The P1647 is still indicating an issue with the Bank 2 H2OS but this may also be a suspect code.

Again thanks for your advice... I will have a look for the approved scanners list for my car and sell my MS509 scanner on E-bay!!!
Cheers,

 

Hi all,
My codes update: I have an Autel MS509 scanner. The codes it pulled off were P1000 P1647 P1642
I took it to a Jaguar specialist who read the codes and came back with the three same ones... I asked him about my scanner and he says it a good little scanner that can read Jaguar codes.
I am having the sensor changed in the morning Bank 2 sensor 1 and hoping to clear the code P1647 also hoping the car will start and run a bit better, it is juddering and shaking at idle.
The Jaguar man said to me that all my components on the CAN-bus are talking to each other, he also believes that the P1642 fault is an artifact of connecting the scanner software to the CAN bus...
Any thoughts?

 

Any thoughts? Yes, I think selling the scanner on ebay would be a good move!

 

The Bank 2 sensor has to go. A consistent P1647 leaves no other choice.

Depending on the subsequent DTC scan, Astromorg's 'doom and gloom' diagnosis of your Autel MS509 may prove correct!
