P1568 Cadillac Code - Cruise Servo Stroke Greater Than Commanded In Cruise
Quick Answer
The P1568 Cadillac diagnostic trouble code (DTC) indicates that the cruise control servo stroke is greater than what was commanded in cruise mode. Common causes include Faulty cruise control servo motor: A malfunctioning servo motor can cause the servo stroke to exceed the commanded range, Throttle position sensor issues: Problems with the throttle position sensor can lead to inaccurate feedback to the cruise control system, Wiring issues: Damaged or corroded wiring connections can disrupt the communication between components in the cruise control system. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
