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 causes a bad intake air temperature sensor?
A bad intake air temperature (IAT) sensor may cause one or more of the following symptoms: lean misfire, usually in a cold engine Faulty EGR system (in some applications) “Check engine” light with diagnostic trouble codes P0112 or P0113
What does the P2017 code on the intake manifold mean?
What the P2017 code means. The runner position sensor, also known as the runner valve, controls the volume of air entering the intake manifold. The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine.
Can a faulty IAT sensor cause an engine to not start?
However, some engines rely on the IAT sensor to turn on the cold-start injector or operate the EGR valve. So a faulty IAT sensor can make it difficult for an engine to start when cold.
When to open and close intake valve actuator?
The ECM compares the two pressure values. The ECM activates a 283-7 code if the pressure difference is too low. The control valve should remain closed during engine operation. The system does not operate until the engine has reached normal operating temperature. Each actuator (4) contains two solenoids (6) .
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.
What are the symptoms of an intake valve problem?
The following symptoms may occur if there is a problem with the intake valve actuation system. You may need to apply a load to the engine in order to verify that the problem is resolved. The test must be performed at 75 percent of the engine’s rated fuel rate for at least 30 seconds.
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.
What is the intake valve actuator solenoid test?
“Intake Valve Actuator Solenoid Test” This test is available on the Caterpillar Electronic Technician (ET). The test helps diagnose problems with the circuits for the solenoids. The following conditions must be met before the test will function:
What causes an oil leak in a C13 engine?
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. The Engine Intake Valve Actuation System Oil Pressure did not change when the Engine Intake Valve Actuation System Oil Pressure solenoid is toggled.
What is the intake valve actuator on ACERT cat?
An Intake Valve Actuator or IVA (also known as a Varible Valve Actuator or VVA) is a device that contacts the intake rocker arm and holds the intake valve of an ACERT Cat engine open in an effort to lower the cylinder temperatures of the engine.
