I have a 2017 F-Type S with a manual transmission. A few days ago the engine icon on the dash turned yellow. I've noticed nothing at all different about how it drives. I used my code reader to read the code and this is what it showed:




Since I haven't noticed anything different about how it drives, I figured that perhaps it was just a freak occurrence. So, I decided to erase the code and to see if it would come back. Unfortunately, my tool said that the erase had failed. When I looked at the code again it had changed from "Current" to "Permanent" which sounds kind of ominous.



Any suggestions regarding what the problem is and how I might fix it are appreciated. I'm unfortunately now out of the warranty period.

 

Check for a vacuum leak or a leak in the pipe/connections between MAF sensor and the throttle body.

 

Could be carbon build up on the Throttle body. Easy enough to remove intake ad clean the throttle body to check.

Oddly, when I started the car the next day, the check engine light was off. So, it appears to have cleared even though the scan tool indicated a permanent fault. Though it's probably just wishful thinking, I'm just going to drive it and see if it comes back. If it does I'll dive in to checking the throttle body and looking for vacuum leaks.

 

Jaguars can have a habit of fixing themselves ....
