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.
EGR vacuum solenoid circuit fault
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.

Fault code FF17 on a 1993 Jaguar XJS typically indicates an issue related to the throttle position sensor (TPS) or its circuit. This code can signify that the sensor is providing incorrect readings to the engine control unit, leading to performance issues. It's advisable to check the sensor's wiring and connections for any damage or corrosion, and to test or replace the TPS if necessary. Always refer to the vehicle’s service manual for specific troubleshooting steps and repairs.
Its just the model name. ie Jag XJS - the Jag is the manufacture and the XJS is the mode ! So with the 50D - Canon is the make and the 50D is the model number.
Fault code FF3 in the Jaguar XJS 3.6 typically indicates an issue related to the engine management system, often linked to the fuel injection or ignition components. This code may suggest problems such as sensor malfunctions or electrical faults that can affect engine performance. It is advisable to conduct a thorough diagnostic check to pinpoint the exact cause and address the underlying issue effectively.
Fault code FF67 on a 1995 Jaguar XJS with a 6.0 V12 typically indicates an issue with the engine's emission control system, likely related to the oxygen sensors or catalytic converters. This can lead to poor fuel combustion and elevated emissions, causing the vehicle to fail state emissions tests. It's advisable to check for any vacuum leaks, inspect the sensors, and ensure the catalytic converters are functioning properly to address the problem. Additionally, scanning for any other related fault codes may provide further insight into the issue.
