DESCRIPTION:This fault code sets when the motor control module (MCM) detects that cylinder #1 has low rpm speed with the injector commanded to max fueling for a count of two with all conditions met. MONITORED PARAMETER:Engine rpm TYPICAL ENABLING CONDITIONS:1. Engine speed steady between 600 to 950 rpm.2. Engine coolant temperature between 65°C (149°F) and 114°C (237°F).3. Engine fuel temperature between 0°C (32°F) and 150°C (302°F). MONITOR SEQUENCE:None EXECUTION FREQUENCY:Once per drive cycle when enabled conditions are met. TYPICAL DURATION:Five seconds DASH LAMPS:1. CEL2. MIL ENGINE REACTION:25% Derate VERIFICATION:1. Ensure the ignitions has ben off for a minimum of 5...

NOTE: Please see the step by step troubleshooting procedures for this specific code. PROBABLE CAUSES:1. Cylinder kit failure.2. Valve train failure.3. Lash adjustments.4. Fuel injector.5. High pressure fuel line (rail to fuel injector).6. Debris entering fuel injector.7. Fuel quality. Note: If 1322-31 active, fix that first.
