DTC P1402 EGR FUNCTION EC-1059 [VG33E] C D E F G H I J K L M A EC EGRC-solenoid Valve The EGRC-solenoid valve responds to signals from the ECM. When On Board Diagnosis Logic UBS00DOE If EGR temperature sensor detects EGR flow under the condition NOTE: °C (122 to 140°F). Therefore, it will be better to turn ignition switch ON (Start engine) at the engine coolant tempera- °C (104°F) when starting DTC confirmation procedure. DTC Confirmation Procedure UBS00DOF NOTE: ● Engine coolant temperature and EGR temperature must be −10 to 40°C (14 to 104°F)* EGR TEMP SEN: Less than 4.8V *: Although CONSULT-II screen displays “ −10 to 40°C (14 to 104°F)” as a range of engine coolant temperature, ignore it. WITH CONSULT-II 1. Turn ignition switch OFF and wait at least 5 seconds, then turn ignition switch ON.
