DTC Set Conditions

Check conditions are when engine is being cranked and battery voltage is 10-16 volts. Judgment criteria is when the EGR solenoid coil surge voltage (battery voltage plus 2 volts) is not detected for 0.2 second. Only one monitor is performed during one drive cycle.

Check conditions are when battery voltage is 10-16 volts, ON duty cycle of the EGR solenoid is 10-90 percent, ON duty cycle of the evaporative emission purge solenoid is zero percent, evaporative emission ventilation solenoid is OFF and more than one second has elapsed after the conditions have been met. Judgment criteria is when the EGR solenoid coil surge voltage (battery voltage plus 2 volts) is not detected for one second.
