Where are the actuators located on an intake valve?
Actuator (4) – The actuators are located under the valve covers. Pressurized engine oil flows from the rail to each actuator. The actuators use the pressurized engine oil and electrical commands from the ECM in order to delay the closing of the intake valves.
What is code for C 13 intake valve actuator?
Replaced jake/intake actuator assembly and had no other problems. Last week light came on and had a code for #2 this time. Replaced the other 2 jake/intake actuator assemblies. Next day light came on again and derated power and now have code for low oil pressure to actuation system.
What is the code for open intake valve?
If the control valve is partially open, a 283-7 code is usually activated in addition to the 385-1 code. Follow the troubleshooting procedure in order to identify the root cause of the problem.
How does the ECM work on an intake valve?
Pressure Sensor (2) – A pressure sensor is threaded into the rail. The sensor converts the rail pressure into an electrical signal. The ECM monitors the signal in order to determine the pressure of the oil in the rail. Control Valve (1) – A control valve is threaded into the rail.
Actuator (4) – The actuators are located under the valve covers. Pressurized engine oil flows from the rail to each actuator. The actuators use the pressurized engine oil and electrical commands from the ECM in order to delay the closing of the intake valves.
Why is my intake valve not working properly?
The intake valve actuator is not responding correctly to the commands from the ECM. This can be caused by the following conditions: There is an oil leak in the system. There is a problem with an actuator. The valve lash is incorrect. The adjustment of an actuator is incorrect.
