Hello, Well I confirmed i am not able to come up with anything for those # I have a 123 then it skips to 131 .. then a 145 athen it skips to a 151 .. this is straight off the cummins site for your ser# .. I did a search on the site and 128 came up as boost senor high voltage.. but didnt meantion a isx.. and there is a code for that anyways
146 came up as a coolant temp sensor.. but again didnt list a ISX
I will relist the question for you, maybe someone else has a Idea, sounds like a general ECM code with no meaning.. but I cant confirm
someone should be with you soon
Hello, Your welcome sorry couldnt help.. take care
EGR Valve Control - Mechanical System not Responding Properly or Out of Adjustment. EGR valve not responding or slow to respond.
Possible low power. Power will be removed from the EGR valve motor.
Possible causes of this fault include:
The ECM monitors the response of the EGR valve and logs a fault code if the valve fails to respond as commanded. When the ECM stops commanding the valve, the fault code will go inactive; therefore, this fault code tree must be used to troubleshoot active and inactive faults.
This also means the only sufficient way to make certain the repair is complete is to run the INSITETM electronic service tool EGR valve test. Operating the engine is not adequate to verify the correct component was repaired or replaced.
