Help! Engine code #32 egr function

[PeterYang]

So I have a 1990 ka24e s13 and check engine light read code #32 which is egr function.... I replace a new egr already but after resetting ecu drove about 30 miles and it came back on reading same code. Any help would be greatly appreciated.

Check all the lines and hoses that are part of the egr state if you haven't already. Do you need it to pass smog? I get this code on and off and ive just learned how to deal with it.
