Diagnostic Procedures
- Normal closed EGR valve position feedback voltage should be between 0.2-1.5 volts. This value may change with temperature.
- A voltage of less than .2 volt indicates a problem with the position feedback circuit. A voltage of greater than 1.5 volts could be caused by a position feedback circuit problem, a valve stuck open or a solenoid being energized.
