CAT C15 MXS IVA warm-up control solenoid question

The rough running condition your talking about is that when you first start down the road and is sputtering or coughing, and puffing out smoke? My MXS will do that too from time to time if I don't let if warm up properly. Code 95 is intake valve actuation oil pressure sensor. Sounds about right on the one you replaced. Should be on the front passenger side of motor by t-state housing. When I turn my key on I also hear clicking noises in the engine area. Sometimes it lasts a short time others it will go on longer.

I will tag @GrapeApe for you he is very knowledgeable on the acerts. Good luck

 

Before all these parts you replaced, did it run fine before?

 

I am getting stumped now. I wonder if there is something wrong with 1 of the other 4 injectors? Is it throwing any codes at you when it is running rough?

 

If there is any stored codes you can retrieve them from using your cruise control toggle switches. To check that you turn your key on, turn your cruise control switch off and then hold your set/resume switch down for a few seconds, then release. Watch your check engine light flash. If it flashes 5 times, then a slight pause, 5 more times (code 55) then that means no codes active.

The rough running problem your describing is most likley the water recirculation valve at the precooler no functioning...they help the motor warm up also by either not allowing or allowing coolant to circulate threw the precooler core. Their is a diaphram behind the valve that can go bad but usually its the 2 wire harness that goes to it and routed behind the turbo and very close to manifold...it becomes melted and brittle from heat and they can short out on motor or themselves not allowing the valve to work. In my experience it normally doesnt through a code. Youll have to run new wires from where they come out of the main harness near the front of the cylinder head by the fuel inlet line. I usually run them up and over the alternator bracket away from the manifold and connect it to the valve near where the heater hoses are fastened to the frame. Stops them from melting again. Hope this helps.
