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.
