I have a Jaguar XJS 1993 model. A light on the dash has come on saying 'check engine'. Using the hadbook procedure the faull FF44 has appeared. I believe the FF stands for Fueling Fault but I do not know what the 44 means
The fault code FF77 typically indicates a fault with the ABS hydraulic unit or the ABS control module in a 1994 Jaguar XJS. It is recommended to have the ABS system diagnosed and repaired by a qualified technician to ensure the system is functioning properly.
Fault code FF17 on a 1993 Jaguar XJS typically indicates an issue with the engine management system, specifically related to the fuel mixture or oxygen sensor readings. This code often points to a problem with the air-fuel ratio, which can affect engine performance and emissions. It’s advisable to check the oxygen sensors and the fuel injection system to diagnose and resolve the issue. Always refer to the vehicle’s service manual for specific troubleshooting steps.
When all else fails, check your Drivers Handbook.
The fuel pump is in the fuel tank.
{| |- | MAF sensor - air flow sensor signal out of range. Possibly due to dirt build-up in the throttle bodies, or on the hot wire airflow sensors. |}
What ff14 means is that there is a fault with the coolant temperature sensor. This could mean a blockage in the system (radiator, thermostat, water pump, etc), the temperature switch, or a loose connection.
