I am looking to buy a Jaguar S-Type from a private seller and the engine light is on with the code P0065 - Air Assisted Injector Control Range/Performance. Does anyone have an idea what this means as well as the damage and cost of repair? I know without looking at the car its hard to tell what the problem is but has anyone had this before and what was the story behind it. Thanks a lot in advance!

 

Being that I don't own a Jag, I'm going to go way out on a limb here and give 2 cents.

Most P-codes that I've dealt with were injector related. If your ECU is fine, which a diagnostic run should be able to verify, then more than likely, its a clogged or failing injector. Changing out fuel injectors isn't usually too tough. Just some wiring and soldering skills needed. If I were buying any car off a private party, I'd get an OK to take the car in for a full diag. out of pocket. Worst case scenario, you shell $100 for the dealer to run the tests...find out its a bigger issue...eat the $100 and keep looking. Vs. the alternative....hoping its as easy as an injector, buying it...and finding out you have a major issue with the ingition system, fuel delivery system, or something way more expensive.

FYI...if it is just an injector...I recommend RC Engineering injectors. Bullet proof! Great company! I'd replace them all if I had a bad one.

 

Exactly what I recommended...the thought of replacing all injectors was only "if" that was the underlying issue that needed to be addressed. I know nothing of the quality of the OEM injectors, so that is why I recommended the aftermarket vendor.
