Hi my name is***** 94 is an Intake valve actuator fault(failed Intake Valve Actuator Solenoid). The solenoid is located on top of the Intake Valve Actuator housing. You can by a two solenoid kit from Cat. for 94 you will be replacing #5 and 6 under the valve cover. They are easy to change and help in by 4 screws.

Fault code 95 is intake valve actuation oil pressure voltage high, or intake valve actuation oil pressure voltage low. Check the sensor and harness. Most commonly it will be the sensor that is faulty. Let me know
