Cummins ISM CM875 (2003-06) Fault Code: 546 PID...

The rail fuel pressure sensor shares supply and return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to...

Cummins ISM CM875 (2003-06) Fault Code: 486 PID...

The ECM estimates the amount of fuel delivered to each bank by monitoring the crankshaft acceleration pattern as it rotates. This fault is set active if the ECM estimates that...

Cummins ISM CM875 (2003-06) Fault Code: 482 PID...

The fuel pressure is monitored by the ECM. If the rail fuel pressure is lower than an acceptable level for a given set of engine operating conditions, the fault code...

Cummins ISM CM875 (2003-06) Fault Code: 449 PID...

The fuel pressure is monitored by the ECM. If the rail fuel pressure is higher than an acceptable range for engine operating conditions, the fault code is logged. Possible repair:...

Cummins ISM CM875 (2003-06) Fault Code: 443 PID...

Low voltage on the +5 volt supply line can be caused by a short circuit to ground in the supply line, a short circuit between the supply line and return...

Cummins ISM CM875 (2003-06) Fault Code: 435 PID...

At key-on, before the engine is started, the sensor readings for barometric pressure, exhaust gas pressure, and intake manifold pressure are compared with engine oil pressure. This fault code occurs...
