What Cummins code 7141 means

The signal wire for Engine Intake Manifold Temperature Sensor Circuit is sitting above the voltage window the ECM expects. In practice that is usually an open signal or return wire (the ECM pull-up takes the input high), a short to the 5 V supply or battery, or a failed sensor element.

It turns on the red STOP ENGINE lamp. Cummins classes this as a fault that can damage the engine or aftertreatment if ignored: stop as soon as it is safe to do so. Many calibrations also apply an engine-protection derate while the fault is active.

On a generic J1939 scan tool, or on the dash of a Freightliner, Kenworth, Peterbilt, International or Volvo chassis, the same fault is shown as SPN 105 FMI 3 rather than as Cummins code 7141. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

J1939 failure mode identifiers (FMI)

FMI 3 is highlighted. The FMI is the second half of every J1939 fault and tells you how the component failed; the SPN tells you which component.

Questions about code 7141

What does Cummins fault code 7141 mean?

Cummins 7141 is "Engine Intake Manifold Temperature Sensor Circuit - Voltage Above Normal or Shorted to High Source". It maps to SPN 105 FMI 3. The signal wire for Engine Intake Manifold Temperature Sensor Circuit is sitting above the voltage window the ECM expects. In practice that is usually an open signal or return wire (the ECM pull-up takes the input high), a short to the 5 V supply or battery

Which lamp does fault code 7141 turn on?

Red STOP lamp: It turns on the red STOP ENGINE lamp. Cummins classes this as a fault that can damage the engine or aftertreatment if ignored: stop as soon as it is safe to do so. Many calibrations also apply an engine-protection derate while the fault is active.

How do I clear or permanently delete Cummins code 7141?

An active code goes inactive on its own once the condition is gone; the inactive record stays in the ECM fault history until it is cleared with Cummins INSITE (or a J1939 tool that supports the DM3 / DM11 clear). If the code keeps coming back because the part is gone, disconnected or not worth repairing, the lasting fix is to disable fault 7141 in the calibration: upload your .xcal to the ECFG Superstore file service, custom DTC delete from $150 (up to 30 codes), full DPF / EGR / SCR delete $500, and flash the returned file with Calterm or INSITE.
