First of all, I posted this a while back.

I apologize if melhookv12 felt ghosted by me on that thread. I left the country for a few weeks and got caught up in other things after I returned. Anyway, it was a dead end.

The real problem was not transmission but a power loss when accelerating from a stop. The third time was the charm with regard to obtaining information. I have not experienced the problem myself but it has now happened three times to my wife. After the third time I got a Code P1584 with the below listed freeze frame information from Autoenginuity.

Fuel system Status Bank 1: Open (driving condition)
Fuel System Status Bank 2: Not Reported
Short Term Fuel Trim Bank 1: -5.46%
Short Term Fuel Trim Bank 2: -5.46%
Long Term Fuel Trim Bank 1: 3.90%
Long Term Fuel Trim Bank 2: 3.12%
Calculated Load: 0%
Coolant Temperature: 212 Deg F
Fuel Pressure: 43.06 Psig
Engine RPM: 1331 RPM
Vehicle Speed 41 MPH

I don't know if this makes sense because the vehicle speed shows 41 mph when the problems happened when starting from a stop.

Can anyone interpret this info for me?

Also, the message display showed "something Failure" or "Fail something" but my wife didn't see all of it. Anyone know how many different messages can be displayed using the word FAIL?

Thanks in advance!

 

I think that code P1584 is related to the throttlebody but I am not sure. It is one of Jaguars codes that can be identified with IDS or SDD code readers.

 

Suspect the power/ground - but especially the battery.
