What does the check engine light vcm code "fuel 14 /fail 14" mean on my jaguar xj6?


this has to do with the engines ability to warm up and meter the fuel. either the thermostat is sticking or the coolant temp sensor is out of range. there are 2 of them at least, one for the guage and one for the pcm. if you find it is the t-stat sticking, replace with jaguar parts.

Check MASS AIR FLOW SENSOR , try to get a used one and fit to the car , it is very easy to install. And by the way the MASS is the part that is in connection with the air filter , the one that has an electrical connector. When installing make sure that it is tight and no leaks. This answer was based on your description and code supplied hope this would help

FUEL FAIL 14 CODE 14


this is the most common error code, just means the one of the nods in fuel pump misfired, on every model other than the ones for usa market, after clearing the error code on vcm the check engine light would reset. for our cars its programmed to stay on.
also get fail 17 fuel 17 same thing
it will not effect the running of the car or its performance
may run a little rich
