Ok D16A6 stock si motor had a B16 dude pulled it. I bought the car for cheap
put back in the stock motor with a brand new harness. The car starts then goes
into limp mode. I checked the voltage its at 19 so i changed the alt and batteryand its still doing it. BUT if i unplug the harness from the alt and run it of battery power it runs fine and throws code 20 WHY ? Both alts cant be bad. so what else could it be a ground some where ? i dunno please help thanks

 

code 20 eld
need to replace under hood fuse box
check your wiring at the fuse box

 

Where is the ELD is it in the ecu ? or is it just a fuse ? i thought it was a fuse
under the dash 14 i think.

 

no eld is part of main fuse box under hood
check your grounds also

 

woo hoo fixed it no more limp mode thanks all!!!!!!
