My manual says code 21 is the vtec solenoid code and 20 is eld. Which do you need help diagnosing?

2 long followed by 1 quick should be code 21. Give me some background, were you driving and all the sudden the cel lit up? You did a harness tuck correct? I would check all those connections.

evan, the ELD is in the alternator, test for resistance between the plug and the ecu pin.

thats random that the alternator was fucked up

i thought ELD was in the fuse box

I'm going to ADD all new 4 gauge grounds everywhere.. ithink that should fix it

i also noticed that when iremoved abs there are a lto of plugs on the harness that aren't plugged in... maybe im forgetting some

I got code 21 b4 and I cleaned the VTEC solenoid and it was gone for good
I am having code 20 (ELD) that I am trying to fix in my chipped P28 running ubderdata, I am trying to find that ELD relay which under the fuse box in the engine compartment of a 4th GEN JDM PRELUDE since I can not turn it off in uberdata.
remember to reset your ECU after clean the VTEC solenoid...

20 is ELD

21 is VTEC solenoid.


21 wouldn't cause your car from starting, just would be a VTEC problem, u suer its not 20 ?

when you turn the key and your only getting a click, that might be also a bad starter (or mybe bad battery connection). I remember my friend's car i used to hammer his starter to get it start.

an ELD code won't keep the car from turning over. you should check all your grouds, especially from the motor to the batery and motor to body.
