Hi All,

New owner of 2014 XJ 3.0L V6. I had my coolant pump replaced and supercharger maintenance done (think rebuilt) and this code showed up the other day. I've tried searching online but haven't found anything.

Has anybody seen this before?

P026A-00 - Charge Air Cooler Efficiency Below Threshold.

I do also have 2 oxygen sensors that I will be replacing soon (bank1&2, sensor 3) and I get the error codes for those as well. (P0062 and P0042)

 

RD12,

I don't have any advice on your Charge air snag.

Check with your dealer about the O2 sensors. Last year JLR extended the warranty on the O2 sensors for a number of models, for certain years. I should, but don't have the exact details to hand. JLR will replace the defective sensors for free. It appears that Bosch supplied a bunch of junk that is causing problems.

Thanks for the info! I'm going to call my local Jag dealer and setup an appointment.
