P1299 on Lincoln
Ford and Lincoln: cylinder head over-temperature protection is active (the engine computer's fail-safe cooling mode)
Severity: Stop — don't drive this car
Ford's workshop manual sets P1299 at the stage where the engine computer cuts cylinders because the engine is overheating, and says long-term engine damage can occur; the next stage shuts the engine off. Stop as soon as it is safe and let the engine cool.
