Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. This fault code is activated when the pressure or temperature input from the OEM sensor exceeds the engine protection limit defined by the OEM. An engine power derate is possible, depending on the OEM application. Possible repairs: 1)Replace the OEM harness.2)If necessary, recalibrate the ECM. PACCAR PX-6 CM2150 (2007-09) Fault Code: 778 PID: SID 064 SPN: 723 FMI: 2 Engine Camshaft Speed/Position – Data Erratic, Intermittent, or...

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.This fault is set active if the ECM does not receive the Heartbeat message from the adaptive cruise control unit on the SAE J1939 data link. If Adaptive Cruise Recovery is enabled, the driver can toggle the cruise enable switch from the OFF position to the ON position two times to get regular cruise control to operate and Fault Code 784 will go inactive. At the next key...

PACCAR MX (2004 Emissions) Fault Code: P0016 Camshaft Speed Signal – Not Corresponding With Engine Position SET CONDITIONS:The PCI ECU (D420) detects that the camshaft sensor (F558) signal does not correspond to the crankshaft sensor (F552) signal (engine position) after some engine revolutions. DIAGNOSTIC CONDITION:This diagnostic runs during starting. CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:This DTC changes to inactive when 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:1. Air gap...

PACCAR MX (2004 Emissions) Fault Code: P0017 Crankshaft Speed Signal – Not Corresponding With Engine Position SET CONDITIONS:The PCI ECU (D420) detects that the crankshaft sensor (F552) signal does not correspond to the camshaft sensor (F558) signal (engine position) after some engine revolutions. DIAGNOSTIC CONDITION:This diagnostic runs during starting. CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:This DTC changes to inactive when the fault is no longer detected. To validate the repair, key the ignition off for at least 15 seconds, key on again. Then start the engine and let it idle for 1 minute. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive...

PACCAR MX (2004 Emissions) Fault Code: P0045 VTG Turbocharger Actuator – Position Error or Internal Error SET CONDITIONS:The VTG turbocharger actuator (L037) detects that:1. The end stops are out of range or2. The calibration procedure with the diagnostic service tool cannot be completed correctly or3. An internal actuator failure is active DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. RESET CONDITION:This DTC will change to inactive after the ignition is keyed off and on again and the diagnostic runs and passes. POSSIBLE CAUSES:1. Temporarily frozen actuator/nozzle ring assembly2. Soot buildup on the turbocharger nozzle ring mechanism3. After installation...
