what does fail safe engine mode mean on a 2000 jaguar s type? how to fix this problem?handle
fuel 44 is heated oxygen sencer bank A other term lambda senser the jag has two.
In 1990-1994 XJ6 the VCM Code 44 is the code for the O2 sensor, either rich or lean exhaust has been detected and is causing the code to trigger. It could indicate a bad O2 sensor.
Code fuel 1 would indicate Oxygen sensor. A good information source is the Haynes Manual Jaguar XJ6 1988-94. Good luck.
I own a 91' XJ6 also and i believe when that code comes up it is as simple as your gas cap not being on all the way
