When I started up a NH T4.75 yesterday I got two error messages. 3003 (Accelerator pedal signal - source low) ??? And 14016 (ADIC 5 volt reference voltage is too high above 6 volts). The tractor started up fine and even after warming up (temp in low 20's) throttle would not respond, but stayed at fast idle. Anyone have any idea what's up. Would be lucky if dealer up here had any idea during the week, but little to no chance on Friday evening.
