p05 error code. FIXED! THANKS MADMAX
 

i got a chipped p05 + vtec and im getting a code 20. i searched around pgmfi.org but no leads. someone there said they disabled the o2 heater but that doesnt solve my issue. any tips would be good. i added q30 transistor also, no luck. also is there a way to disable the vtec circutry w/o having to remove all the parts i added? just for troubleshooting purposes.... thanks

Re: p05 error code.
 

yeah cut J10... think that will bypass VTEC...

wait..code 20? that the electrical load detector...just disable it in CROME...

Re: p05 error code.
 

I've had a couple ECUs that always threw a CEL 20 when you jumpered the diagnostic plug, but they didn't set a CEL on the dash.

Re: p05 error code.
 

it is disabled. its confusing the crap out of me. ill try cutting j10 and see if it works ok. then ill know if its something i fucked up when i added the vtec parts.

Re: p05 error code.
 

I thought J10 just made it possible to run one switch rather than run two 5150's in series.

Re: p05 error code.
 

Amusing to watch you take ECU advice from someone who doesn't know what they are talking about, in a thread I posted my commentary in.

J10 has zero to do with CEL 20, dildoes.

Re: p05 error code.
 

either way, it didnt work. ....

i tried a different bin on crome and the cell went away. so i uploaded a different bin and i got a cell. tried this several times and it works with some and not with others. weird ----. same code. ill be hooking it up to the ostrich tomorrow and see what changes it doesnt like with rtp. dam p05.

also, the code may not be eld. i get two long solid lights, then an extremely short flicker. i cant 100% say its a short light, its too short, the light doesnt come on fully. im not sure its a code 21. i know theres nothing with the vtec solenoid, no codes with the stock p28. it may just be a gliche? anyone seen that before?

Re: p05 error code.
 

RENE, it's probably code 21. Is it a 1720 board? They flash the single digits really fast unlike the 11F0 boards.

Re: p05 error code.
 

your right it is. so then what does that mean? somethings bad with the chipping right? what would cause that to happen in a p05 and not in the p28?

Re: p05 error code.
 

Did you set up the resistors in RM11 correctly.

1-2 10K
2-3 51K
3-8 12K

Also make sure the transistor in Q26 is in the correct way, not backwards.


Just recheck everything and then see how it goes.
