1. Cruise control not working: If the cruise control switch signal is not properly recognized, the cruise control system will not be able to engage or maintain a set speed.
2. Engine performance issues: The throttle body plays a crucial role in regulating the air and fuel mixture entering the engine. Incorrect signals from the cruise control switch can disrupt the throttle body's operation leading to rough idling, stalling, or hesitation during acceleration.
3. Warning lights: The code P1586 may trigger the illumination of the check engine light or other warning indicators on the instrument panel.
To resolve the issue, the throttle body control system and the cruise control switch should be thoroughly inspected and diagnosed. This may involve checking for loose or damaged wiring connections, faulty cruise control switches, or issues with the throttle body itself. It is recommended to have a qualified mechanic or technician diagnose and fix the problem to ensure the safety and proper functioning of your Jaguar S-type.
