514 SPN Fault Code

Name:

Nominal Friction � Percent Torque

Description:

The calculated torque that indicates the amount of torque required by the basic engine itself added by the loss torque of accessories. It contains the frictional and thermodynamic loss of the engine itself, pumping torque loss (SPN 5398), and the losses of fuel, oil and cooling pumps. The data is transmitted as a percent of reference engine torque (see the engine configuration message, PGN 65251).The realization can be done by a map dependent on engine speed and engine temperature and an offset value for additional loss torques. See SPN 2978 for an indicator that describes the possible inclusion of engine parasitic losses such as cooling fan, etc. in this parameter value. Note: Refer to section 5.2.1 in SAE J1939-71. Note: Beginning in 2016, HD-OBD requires reporting of engine torque to Portable Emissions Measurement System (PEMS) equipment that is representative of torque as measured by the engine dynamometer during the emissions certification process. Therefore, for applications that

514 spn fault code name is Nominal Friction � Percent Torque. If you don't take the time to look into 514 spn fault when it arises, it can add up quickly. One small issue like 514 can cause a larger component to become damaged without taking the time to investigate. If you suspect your truck is suffering from one of these issues, look into replacing those small components to save money down the road.

Note: The name and description of 514 code represents text descriptions for faults supported by another coding system and does not necessarily comply with SAE J1939. For a specific engine manufacturer's explanation for codes, please consult the engine's technical manual. See also other spn codes.
