The EGR error code.
« on: March 01, 2018, 10:10:47 PM »
Periodically I get the SERVICE ENGINE light, and using the chart and shorting lead, I get #12, which is supposed to be EGR fail.  I can reset it, but days or weeks later It comes on again.  IF I just leave it alone, it will reset after some days.

I think my EGR valve works just fine.  Is there something else I should check?

I had the same Code for the EGR,  The light came on  4 times, in one month,, I cleaned out the EGR Valve two different times.
 it  was really easy to do.

So Far it seems OK.

 I just pulled it off    The Gasket can be reused,   SO  be gentle.
   I  scraped out the black gunk,  I used some small pick tools and a bit off carb cleaner. Pipe cleaner on the tube. 
 Then scraped inside the motor side, I held the vacuum cleaner next to the scraper to keep the particles out of the motor.
    DONT!!! go to deep into the Mushroom Valve.   Bolted it on &   cleared   codes.

My 1991 Rocky ( US ) service engine light went on, checked codes and rung up #12, Checked and cleaned whole EGR system, cleared codes and after 15 or 20 miles it comes on again. been going back and forth for 3 months now and can't get the light to stay off. Coughed In the beginning at low rpm under load,in the beginning, but now runs great.
