fault codes... tables?
Does any one have the Fault code table for the 1992 XJS v12
I am get a FF 13
it showed up after I had a dead bank B
which I fixed with in 5 minutes...
she runs ok now...

the jaguar FF system isn't too specific. In OBDII systems 13 is generally a misfire and then it will have two more numbers following it to be more specific. Without finding a guide FF13 pretty much means you have/had a ignition problem or misfire.

Fault code Description Function
11 Idel pot or associated wiring Looks for idle trimpot out of normal operating range.
13 Pressure sensor Checks for manifold pressure difference and engine cranking
and engine running.
14 Coolant thermistor or associated wiring. Looks for coolant thermistor static during engine warm up.
16 Air thermistor or associated wiring. Looks for air thermistor resistance out of range.
17 Throttle pot or associated wiring. Looks for throttle pot resistance out of range.
18 Throttle pot/airflow meter calibration. Looks for low throttle pot siginal at high airflow.
19 Throttle pot/airflow meter calibration. Looks for high throttle pot siginal at low airflow.
23 Fuel supply. Looks for poor feedback control in rich direction.
29 ECU self check. Checks microprocessor function.
34 Right-hand 'A' cylinder bank injectors and Looks for Injector dribble.
