(M) Malfunction Indicator Lamp (MIL) illuminated during engine operation if this DTC was recorded (depending if required by CARB and/or EPA). MIL is displayed as an engine icon on instrument panel. (G) Generator lamp illuminated P0134 (M) 1/1 O2 Sensor Stays at Center Neither rich or lean condition is detected from the oxygen sensor input. P0135 (M) 1/1 O2 Sensor Heater Failure Oxygen sensor heater element malfunction. P0136 (M) 1/2 O2 Sensor Heater Circuit Malfunction Oxygen sensor heater element malfunction. P0137 (M) 1/2 O2 Sensor Shorted To Ground Oxygen sensor input voltage maintained below normal operating range. P0138 (M) 1/2 O2 Sensor Shorted To Voltage Oxygen sensor input voltage maintained above normal operating range. P0139 (M) 1/2 O2 Sensor Slow Response Oxygen sensor response not as expected. P0140 (M) 1/2 O2 Sensor Stays at Center Neither rich or lean condition is detected from the oxygen sensor. P0141 (M) 1/2 O2 Sensor Heater Failure Oxygen sensor heater element malfunction. P0143 (M) 1/3 O2 Sensor Shorted To Ground Oxygen sensor input voltage maintained below normal operating range. P0144 (M) 1/3 O2 Sensor Shorted To Voltage Oxygen sensor input voltage maintained above normal operating range. P0145 (M) 1/3 O2 Sensor Slow Response Oxygen sensor response slower than minimum required switching frequency. P0146 (M) 1/3 O2 Sensor Stays at Center Neither rich or lean condition is detected from the oxygen sensor. P0147 (M) 1/3 O2 Sensor Heater Failure Oxygen sensor heater element malfunction. P0151 (M) 2/1 O2 Sensor Shorted To Ground Oxygen sensor input voltage maintained below normal operating range. P0152 (M) 2/1 O2 Sensor Shorted To Voltage Oxygen sensor input voltage sustained above normal operating range. P0153 (M) 2/1 O2 Sensor Slow Response Oxygen sensor response slower than minimum required switching frequency. P0154 (M) 2/1 O2 Sensor Stays at Center Neither rich or lean condition is detected from the oxygen sensor. P0155 (M) 2/1 O2 Sensor Heater Failure Oxygen sensor heater element malfunction. P0157 (M) 2/2 O2 Sensor Shorted To Ground Oxygen sensor input voltage maintained below normal operating range. P0158 (M) 2/2 O2 Sensor Shorted To Voltage Oxygen sensor input voltage maintained above normal operating range. P0159 2/2 O2 Sensor Slow Response Oxygen sensor response slower than minimum required switching frequency. P0160 (M) 2/2 O2 Sensor Stays at Center Neither rich or lean condition is detected from the oxygen sensor. P0161 (M) 2/2 O2 Sensor Heater Failure Oxygen sensor heater element malfunction. P0168 (M) Decreased Engine Performance Due To High Injection Pump Fuel Temp Fuel temperature is above the engine protection limit. Engine power will be derated. 25 - 4 EMISSION CONTROL SYSTEMS DN DESCRIPTION AND OPERATION (Continued) |
