: As the connection degrades, it generates more heat (becoming "hot" to the touch or even melting).
The phrase typically refers to a specific failure point in modern diesel engines—specifically the Duramax L5P (2017–2023) —where the BD Diesel fuel injector connectors and pigtails overheat due to increased electrical resistance . This "hot" condition often triggers diagnostic trouble codes (DTCs) ranging from P0201 to P0208 , indicating a circuit malfunction in one of the cylinders.
