My question is in relation to the first one I guess.. My father is a truck driver and hes out on the road right now but he keeps getting this diagnostic code error. The errors are 55 and 93. He has a 2007 Kenworth truck with a CAT engine. Any help would be greatly appreciated if anyone knows what they translate to.

Thank you

If the CAT owners manual is still in the truck they're listed in there.

does any body know what 5 volt below normal code 232.4 mean

Send me a Private Message and I will give you a link to a program that will look up any codes in any heavy diesel engine including CAT. I can not post links here as per rules.

Sorry it didn't come out as good as I thought it would,but Cat Wrench done it far better

I have a CAT 3406E showing a fault code 1-11 which is showing as "cylinder 1 fault" on the posted PDF file for codes. Does anyone know what the sensors interpret? i.e. Injector, compressor, valves??????

My engine is a 1994 CAT 5EK. I don't have the first set of codes. It is flashing blink pause blink-blink. I am reading this as 1-11. Am I reading this correctly or is there another way of interpreting the code?

That would be a code 12. blink=1 pause blink blink=2. If you had a "blink blink blink blink blink", pause, "blink blink blink blink blink" = 55 mean no fault codes.
