Description Cause for Setting DTC
111 Closed Loop Multiplier High (LPG) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation and cannot correctly
modify the fuel flow within its limits.
112 HO2S Open/Inactive (Bank 1) This fault will set if HO2S 1 is cold, non-responsive, or inactive for 60 seconds or longer.
113 HO2S Open/Inactive (Bank 2) This fault will set if HO2S 2 is cold, non-responsive, or inactive for 60 seconds or longer.
121 Closed Loop Multiplier High Bank 1 (Gasoline) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation. When the multi-
plier cannot correctly modify the fuel flow within its limits, the limit is enforced.
NOTE: If this DTC is set in conjunction with DTC 132, the HO2S sensors may be cross connected.
122 Closed Loop Multiplier Low Bank 1 (Gasoline) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation. When the multi-
plier cannot correctly modify the fuel flow within its limits, it is limited at -35%.
NOTE: If this DTC is set in conjunction with DTC 131, the HO2S sensors may be cross connected.
124 Closed Loop Multiplier Low (LPG) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation. When the multi-
plier cannot correctly modify the fuel flow within its limits, it is limited at -35%. When this condition
occurs, the EPM perceives the engine to be running rich.
125 Closed Loop Multiplier High (Natural Gas) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation. When the multi-
plier cannot correctly modify the fuel flow within its limits, it is limited at 35%. When this fault occurs,
it is because the EPM perceives the engine to be running lean.
126 Closed Loop Multiplier Low (Natural Gas) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation. When the multi-
plier cannot correctly modify the fuel flow within its limits, it is limited at -35%. This occurs when the
module perceives the engine to be running rich.
131 Closed Loop Multiplier High Bank 2 (Gasoline) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation. When the multi-
plier cannot correctly modify the fuel flow within its limits, the limit is enforced.
132 Closed Loop Multiplier Low Bank 2 (Gasoline) This fault sets if the Closed Loop multiplier exceeds the limits of normal operation. When the multi-
plier cannot correctly modify the fuel flow within its limits, it is limited at -35%.
141 Adaptive Lean Fault (High Limit- Gasoline) This fault sets if the Adaptive multiplier exceeds the limits of normal operation.
142 Adaptive Rich Fault (Low Limit Gasoline) This fault sets if the Adaptive multiplier exceeds the limits of normal operation.
143 Adaptive Learn High (LPG) This fault will set if the adaptive multiplier exceeds the limits of normal operation.
144 Adaptive Learn Low (LPG) This fault will set if the adaptive multiplier exceeds the limits of normal operation.
145 Adaptive Learn High (Natural Gas) This fault will set if the adaptive multiplier exceeds the limits of normal operation.
146 Adaptive Learn Low (Natural Gas) This fault will set if the adaptive multiplier exceeds the limits of normal operation.
161 System Voltage Low This fault will set if the EPM detects voltage less than 9.5 for 5 seconds or longer while the alternator
should be charging. The adaptive learn is disabled due to the inability of the EPM to correctly time
injector openings.
162 System Voltage High This fault will set if the EPM detects voltage greater than 18 volts for 3 seconds at anytime the engine is
cranking or running. The adaptive learn is disabled due to the inability of the EPM to correctly time the
injector openings.
The EPM will shut down with internal protection with more than 26 volts. A fuse will then blow in the
harness.
