51-4 is for the engine throttle valve signal out of range low . I would start by checking the connection at that actuator . It is located in the intake pipe after the charge air cooler on the outlet pipe .
3464-3 is also a code for engine throttle control shorted out to power . You may be dealing with a faulty throttle valve or a bad connector . We need to inspect the connector for any spread terminals or fretting.
