92 Loyale Bad ECU?


Recommended Posts

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?

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...
