Bro..
Normally for hondas, we only mention the center grp of digits...
In your case P27... so it should be the same spec...(except manual & auto).
Can be modified to prevent Check light for auto...

Any special reason to replace it???

For the below P27-T00 was for a manual transmission car...

Pls link if need repair....

Hi E-Tech,
TQVM for your reply!

I also get the info from a blog saying that T01 (manual) is a later version from T00.
So i think (?), they can be inter-changeble.
But i have better re-confirm T01's pin-out before proceed for "plug and play".

As you guess, T00 is gone case. So will be replace by T01 ;)

 

[E-Tech]

Bro...
Welcome.. and fyi... honda pin out are all the same.
In your case... you are having OBD1, so all obd1 have the same pinout...
e.g p27, p28. p08, p30 all can plug & play... differents are got vtec onot, knock board onot..
Just plug and play and if no CEL then 100% okay....

How bad is the T00 ecu? If you dun have any plans for it pls donate to me...
Tq

 

[levin818]

Thats amazing, Honda has same pin-out for OBD1 ECU.
For Toyota, all has its own pin-out.

Btw, there are many people doing ECU repair in zth.
Myself too, has done more that 700's (Toyota, Honda, Mitsubishi, etc)
That T00 already injected with new life, and ready to run better than before.

Code 41 - O2 heater
Possible area:
1) O2 not connected / wiring broken.
2) ECU problem / QM3 short circuit.
Please f/back after check...

 

[E-Tech]

Bro
sensor checked- ok
qm3- change new twiced

still cannot...
U repaired ant ecu wit this symptom before?
Tq

 

[levin818]

Haha... tough one
Code 41 appears when IC8 of the ECU didn't read the heater's impedance.
Try check Q15 (SMD) , which send the impedance info to IC8.

Never have this symptom ECU before. But have one P27 with CEL always on and can't shows any error codes at all. Dead brain maybe....

 

[E-Tech]

Bro
q15 also changed oledi..
Gonnalah tis p30...
Any other ideas...to trick it so no cel?

The main chip or others might be kill by the surge current already.
(especially if you have a burnt hole under the cap 220/35)
Unless you can replace all the chip that connected directly to B+, otherwise the only way is to bid farewell to this ECU lor

 

[freeman1314]

Wah...u all really scaring me with this ECU burned up stuff la.
Never knew ECU are so fragile.

 

[E-Tech]

After 10years... Anything and everything will
happen to da ecu....

Levin818,
but this ecu caps all good and no burn or leak
just the cel41.....

how to trick ic2? Tq...
