Battery voltage is more than 10 volts. Code will set if ventilation solenoid coil surge voltage (system voltage plus 2 volts) is not detected within 30 milliseconds. Only one monitor runs during drive cycle.
Battery voltage is more than 10 volts. ON duty cycle of EVAP purge solenoid and EGR solenoid is 0 percent. EVAP ventilation solenoid is ON. More than 1 second has elapsed since the above mentioned conditions have been met. Code will set if purge solenoid coil surge voltage (system voltage plus 2 volts) is not detected 1 second.
