DTC Set Conditions

Check condition is when battery voltage is 10-16 volts. Judgment criteria is when the evaporative emission ventilation solenoid coil surge voltage (battery voltage plus 2 volts) is not detected for 0.2 second. There is only one monitor during one drive cycle.

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