PACCAR MX (2004 Emissions) Fault Code: P140E Crankcase Ventilation Module Rotor Speed – Data Valid but Too Low, Most Severe SET CONDITIONS:The PCI ECU (D420) detects that the measured rotating speed of the internal element is less than 8000 rpm for longer than 10 seconds. DIAGNOSTIC CONDITION:This diagnostic runs:1. 600 seconds after the engine has been started and2. When coolant temperature is above 140°F [60°C] and3. System state is not stationary or cranking and4. Engine operating mode is not test mode CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:This DTC changes to inactive when the fault is no longer detected. REPAIR VERIFICATION:1....

PACCAR MX (2004 Emissions) Fault Code: P1458 EGR Temperature – Data Erratic, Intermittent, or Incorrect SET CONDITIONS:The PCI ECU (D420) detects that measured EGR gas flow temperature differs too much from the expected EGR gas flow temperature for more than 40 seconds. DIAGNOSTIC CONDITION:This diagnostic runs:1. 150 seconds after an engine start2. When the coolant temperature is above 65?C [149?F] and3. The engine mode is DOC heating or DPF regeneration or SCR heating or SCR high efficiency or standard or protection. CORRESPONDING OBD READINESS MONITOR:EGR system monitor RESET CONDITION:This DTC changes to inactive when the fault is no longer detected....

PACCAR MX (2004 Emissions) Fault Code: P1480 EGR Valve Module Position – Unable to Reach Target SET CONDITIONS:The EGR valve module (L095) detects a difference between the actual shaft position and the requested shaft position for more than 5 seconds. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:This DTC changes to inactive after the ignition is keyed off for at least 15 seconds and keyed on again, and the fault is no longer detected. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic conditions and set...

PACCAR MX (2004 Emissions) Fault Code: P1481 EGR Valve Module Current – Data Valid but Too High SET CONDITIONS:The EGR valve actuator (L095) detects that the measured actuator current is greater than a temperature-dependent value for more than 6 seconds. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:This DTC changes to inactive as soon as the fault is no longer detected. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic conditions and set conditions.3. Did the DTC come back?– No, repair successful– Yes, repair unsuccessful POSSIBLE...

PACCAR MX (2004 Emissions) Fault Code: P1482 EGR Valve Module – Internal Error SET CONDITIONS:The EGR valve module (L095) detects an internal error. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:This DTC changes to inactive after the ignition is keyed off for at least 15 seconds and keyed on again, and the fault is no longer detected. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic conditions and set conditions.3. Did the DTC come back?– No, repair successful– Yes, repair unsuccessful POSSIBLE CAUSES:Faulty EGR valve actuator...
