2003 ZD30 3L code 1003

[Navara03zd30]

Hi everyone appreciate you taking the time to read.
My d22 has a flashing engine light with code 1003 EGR valve .Comes on as soon as you pull off , tried resetting ecu no luck . It has EGR blank and swirl mod (by previous owner) .
I have scanned through the wires off the egr solenoid and don’t see any issues besides a bit hardened .
Is there a fuse I’m not aware of perhaps for the EGR ? Or could it possibly be incorrect vacuum hose setup ?

There’s no symptoms other than the light constantly flashing .

Any help would be great thanks

The older cars (mine included) had no flow detection, but did monitor that the EGR valve was there. It's likely that the valve itself has a fault if the wiring is ok. That could persist until you pop a replacement on it. If it were mine, I'd assume that a car wouldn't be in an accident just because the EGR valve failed, so getting one from a wreck (even a front-end wreck) would be a fairly safe bet.

check for voltage at the valve. if no voltage it runs via ecm relay and a 10amp fuse.
the ecu only checks the windings, the valve windings should be about 13-17 ohms.
