Fault code

Low coolant level.

 

When you have any code with a "P" in it, it is an inactive or old code. "A" means a currently active one. Those codes could be several hundred hours old. Unless they become active I wouldn't worry about it. The LCD display just displays inactive and active codes it finds on the datalink. Some codes are displayed in error. International doesn't really recommend using that display for any kind of troubleshooting. The LCD display isn't a proper code reader. Unless there is a definite problem with the engine, or abs system and a "CHECK" or "WARN" engine light, the codes in the LCD should be ignored.

 

The "128" is the address the fault is coming from. All vehicles 128 is the engine. 92 is satellite or something not factory. The 155 code is something to do with the EGR differential pressure sensor or circuit. Likely a bad sensor. When I search the Cummins site for the 156, I get no results found. That is the problem with the LCD display. It doesn't always read properly. Keep an eye on your coolant level. A bit of condensation could have frozen in the EGR differential pressure sensing tube and cause a restriction which cause the other code. If you get another check engine light, just toggle through the faults again to see which one has an "A".

 

Ok so we have a 2006 international 9400i it is coming up with the code 092:F02 PID102.A any idea what's this code means?

 

If you are getting that from the LCD display, it means nothing. It isn't a fault code. It is a data message. The LCD display is not a proper fault reader. Unless you have a check engine light, those are to be ignored. If you have a check engine or abs warning light, you need a proper scanner.
