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.
 
 
No change, the CEL is still on.  Does this mean the ECU is bad?

Means you need to replace the egr solenoid

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.

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.radioshac...oductId=2062312

1/2 watt is fine.

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...

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.

No luck, tried the 33 ohm resistors and didn't work.  Any other ideas?
