DTC Set Conditions

• Engine is being cranked.
• Battery voltage is 10-16 volts.

Judgement criteria is when the EGR solenoid coil surge voltage (battery voltage plus 2 volts) is not detected for 0.2 second. The PCM monitors for this condition once during the drive cycle.

• Battery voltage is 10-16 volts.
• ON duty cycle of the EGR solenoid is 10-90 percent.
• ON duty cycle of the EVAP purge solenoid is zero percent.
• EVAP ventilation solenoid is OFF.
• More than one second has elapsed after the conditions have been met.

Judgement criteria is when the EGR solenoid coil surge voltage (battery voltage plus 2 volts) is not detected for one second when the EGR solenoid is turned off.
