koticimage Posted August 25, 2013 Share Posted August 25, 2013 I need a little help. I have a 92 4wd Loyale Wagon that I need to smog in. Runs great but the CEL is on. Just drove 850 miles and got an average of 34mpg. Hooked the green test cables up on the driver's side in the engine bay and shows a code 34. I jumped the cables at the EGR solenoid, as described in this forum along with disconnecting the battery to clear the codes. http://www.ultimatesubaru.org/forum/topic/103456-cel-34-and-35-1990-loyale/?p=1182243 No change, the CEL is still on. Does this mean the ECU is bad? Link to comment Share on other sites More sharing options...
l75eya Posted August 25, 2013 Share Posted August 25, 2013 Means you need to replace the egr solenoid Link to comment Share on other sites More sharing options...
Gloyale Posted August 25, 2013 Share Posted August 25, 2013 You can install a resistor (33ohm) across the solenoid connector this will turn the CEL off, but probably won't pass smog like that unless they just don't notice. Link to comment Share on other sites More sharing options...
koticimage Posted August 25, 2013 Author Share Posted August 25, 2013 Thanks for the quick response. Does it have to be a certain wattage? My local Radio Shack only has the 1/2 watt ones, will these work? http://www.radioshack.com/product/index.jsp?productId=2062312 Link to comment Share on other sites More sharing options...
Gloyale Posted August 25, 2013 Share Posted August 25, 2013 1/2 watt is fine. Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted August 26, 2013 Share Posted August 26, 2013 Could also be a wiring issue. Thought I had a bad ECU when I couldn't figure out my IAC code... turned out it was the wires right at the plug on the harness side. If I moved the wires, it was golden. I'd check the wires at the plug back to the ECU or at least the main harness bundle at the driver's side head... Link to comment Share on other sites More sharing options...
koticimage Posted August 26, 2013 Author Share Posted August 26, 2013 Thank you for your suggestions, I have pulled the ECU and examined the wiring that I could see along with the ECU pins and they all seem ok. I'll head over to Radio Shack in the morning to pick up some resistors and see if that works. Link to comment Share on other sites More sharing options...
ivans imports Posted August 26, 2013 Share Posted August 26, 2013 I use the soiliniods from newer outback/legacy do the same job but way tougher use 2.5d egr soiliniod Link to comment Share on other sites More sharing options...
koticimage Posted August 26, 2013 Author Share Posted August 26, 2013 No luck, tried the 33 ohm resistors and didn't work. Any other ideas? Link to comment Share on other sites More sharing options...
