Sorry, wrote that in a rush. This may need further diagnosis before buying a new EGR.
Was P0403 there all the time? What did you do to get this? Did you unplug EGR solenoid?
P0403:
- Bad EGR solenoid
- Excessive resistance in control circuit (PCM controlled ground) due to an open, chafing or damage to the harness
- Poor connection at the EGR solenoid harness (worn or loose pins)
- Water intrusion at the EGR solenoid harness
- Blockage in EGR control solenoid holding solenoid open or closed causing excessive resistance Loss of supply voltage to EGR solenoid
- Bad PCM

OK, then you need to check the wiring to it. Make sure the plug is on properly. P0403 is the ECM saying there is something wrong in the EGR solenoid circuit.
