Cummins ISL CM850 (2003-06) Fault Code: 471 PID: 98 SPN: 98 FMI: 17 Engine Oil Level ? Data Valid But Below Normal Operational Range ? Least Severe Level. Low oil level has been detected by the oil level sensor.
Cummins ISL CM850 (2003-06) Fault Code: 471 PID: 98 SPN: 98 FMI: 17 Engine Oil Level ? Data Valid But Below Normal Operational Range ? Least Severe Level. Low oil level has been detected by the oil level sensor.
If inactive counts of Fault 471 are logged in the ECM, it could be possible that the engine was running or keyed on while tilted at an angle severe enough to cause this fault to be triggered.
Other causes of fault code 471 may include:
1)The engine may not have been filled to proper capacity during the most recent oil change
2)External engine oil leaks (oil leaking onto the ground)
3)Internal engine oil leaks (oil leaking into the fuel system or cooling system)
4)High engine oil consumption/power cylinder failure (check for abnormally high blowby when the engine is loaded).
On-Board Diagnostic (OBD) Information:
1)The ECM illuminates the appropriate amber or red fault lamp when the diagnostic runs and fails
2)The ECM turns off the appropriate fault lamp when the diagnostic runs and passes.
Possible repairs:
1)If low engine lubricating oil level has been detected. Add engine lubricating oil to the engine.
