What are the ISX fault codes for Cummins trucks?
What are the ISX fault codes for Cummins trucks?
ISF 2.8, ISF 3.8, ISB, ISC, ISL, ISLe , ISDe , QSB 3.3 A high signal voltage or an open circuit is detected in the coolant temperature sensor circuit. The ECM detects that the coolant temperature sensor signal voltage is greater than 5.13 VDC for more than 1 second.
When does an ISX fault code become active?
The pressure in the intake manifold exceeded the maximum allowable value for a given engine rated power. This DTC becomes active when the pressure in the intake manifold exceeds the maximum allowable value for a given engine power rating. ISF 2.8, ISF 3.8, ISB, ISC, ISL, ISLe , ISDe , QSB 3.3
When do I get the fault code 2398?
The fault code is set when the actual position of the drive changes the geometry of the turbocharger does not match the specified for more than 10 seconds. Error code 2398 Engine:
What’s the fault code for a Cummins derate?
It sets fault code 3714 – Engine Protection Torque Derate – Condition Exists. The driver display says 25% torque derate in 3 hours. It starts to count down, but never goes 3 hours until it clears itself.

Why does my ISX truck refuse to start?
The truck sat overnight and mosat of the day yesterday, and then around 3pm i went to start it and it did the same thing as it did over their lube pit. I pulled the fuel filters and found the fuel levels inside to be low.
It sets fault code 3714 – Engine Protection Torque Derate – Condition Exists. The driver display says 25% torque derate in 3 hours. It starts to count down, but never goes 3 hours until it clears itself.
What should I do if my Cummins ISX wont run?
Start it up, run for 10 seconds or so (until the ecm recognizes that the oil pressure isn’t coming up I suppose) then shut down. Low on coolant, same thing. Should have code for low coolant or oil pressure if that was the case i would think.
Is there an issue with the 187 Cummins?
The only issue with 187 is for sensor supply #2 which includes the cam position sensor, not the engine position sensor. With the loss of the cam sensor the engine will derate, really shouldn’t shut down. With the loss of the cam sensor the ECM relies on the engine position sensor and vise versa.
What kind of camshafts does a Cummins ISX have?
Dual overhead camshafts: If your ISX was manufactured before 2010, it has a dual camshaft system. The first cam creates high-pressure fuel injection for clean power while the second has a set of lobes to operate the integrated engine brake. The second set of camshafts also moves the intake and exhaust valves.
What does ECM mean on an intake manifold?
The ECM determines that the voltage signal of the pressure sensor in the intake manifold exceeds the value specified in the calibration for more than 1 second. ISF 2.8, ISF 3.8, ISB, ISC, ISL, ISLe , ISDe , QSB 3.3 The intake manifold pressure sensor circuit is undervoltage or short circuit.
What are the fault codes for Cummins oil pressure sensor?
A low signal voltage or an open circuit is detected in the oil pressure sensor circuit. The ECM determines that the oil pressure sensor signal voltage is less than 0.25 VDC for more than 16 seconds. ISF 2.8, ISF 3.8, ISB, ISC, ISL, ISLe , ISDe , QSB 3.3 A high signal voltage or an open circuit is detected in the coolant temperature sensor circuit.

Why is the speed sensor not working on my Cummins truck?
The engine speed signal from the camshaft position sensor is not detected. Possible causes for this DTC are damage to the camshaft position sensor, an open or short circuit in the circuit, or a fault in the power circuit. The engine speed signal from the crankshaft position sensor is not detected.
