DTC Set Conditions

Check conditions are ignition switch: "OFF" to "ON" and EGR valve in operation after the engine starting process is complete. (While EGR valve is initialized.) Judgement criteria is where the EGR valve motor coil surge voltage (battery positive voltage +2V) is not detected for 3 seconds. The PCM monitor for this condition runs once per drive cycle.
