Got a 90 subaru loyale with ea82 and has code 34 which is egr solenoid and im wondering how do i know for sure its that and what can i replace it with... Please help

Find the EGR valve

follow the rubber control hose to the solenoid.

 

Measure the coil resistance of the solenoid

should be around 35 ohms.

 

If infinity (open) it's toast.

 

Very common problem.

 

Gat a similar solenoid from almost any Honda or Toyota of that

era and change the connector.

 

Plenty of posts on this subject, sir.

Hope this helps.

This is my solution:

Take your electrical tester to the junk yard and pull a good one from another soob. I did this for my purge canister solenoid on my ej22. Someone beat me to the Fairfield pnp and pulled the solenoids off every single legacy in the yard. I couldn't believe it. I did find one in the next yard I went to, but bring your tester, because you want to know you're getting a good one.

What he said ^^

 

Bring your multimeter with you, find one with a good resistance value, 35 ohms.

 

That's what I do.

Or you can replace the solenoid with a 33 Ohm, 5 watt resistor. Plug the vac lines or plumb the EGR to receive vacuum at all times. Your choice. This way you never worry about the solenoid failing again. You can also do the same thing with the Purge solenoid. Neither are needed for proper operation of the SPFI.
