Where are the 555 and 556 codes on a Cummins?
555 and 556 is for the breather filter on the side of the engine. There should be a large plastic looking box at the front left corner of the engine. There is a crankcase filter in there that is overdue for changing.
What are the fault codes for a Cummins Engine?
crankcase pressure is too high when vent is bad ore piston/ring is bad. but usually it is bad sensor issue. 559 – low fuel pressure… is it stored code ore active every time engine running? 555 and 556 is for the breather filter on the side of the engine.

What causes broken cranks on a Cummins v-555?
Reports of “broken cranks”, “spun bearings” and “thrown rods” NOT caused by “ Hydrolocking ” are far too frequent. This weakness, however is common of most smaller “V” cylinder configuration engines, especially those with cylinder bores less then 5 inches (127mm) and is due to the overall shortness of the crankshaft.
Why is my SPN 101 fault code 556?
REASON: Crankcase Pressure – Data Valid but Above Normal Operational Range – Most Severe Level. EFFECT: Engine power derate. The pressure inside the crankcase is measured by the crankcase pressure sensor. When the crankcase pressure sensor determines that the crankcase pressure is higher than normal, this fault code is logged.
What to do after a fault code 556 occurs?
After Fault Code 556 occurs, it is important to check for progressive damage to the engine due to the high crankcase pressure. Check for oil leaking from gaskets and seats. Subscribe to receive free email updates:

What to know about the ISX fault code 559?
about code 559… check for rail fuel pressure with Insite software. if it drops under load look for “cheap” problem first, like filters, tank ventilation, air in fuel, bad fuel lines…. There are two fuel pumps – priming pump (used before start) and gear driving pump. This pump may be worn, may suck air/oil, ore drop pressure under load
