FG2 K24A2 TB-J37 8kRPM problem

[dvergara]

Hi all, i have a problem with my FG2 2010 and any help would be much appreciated. my car is fitted with a hondata flash pro. when i am driving the car at full throttle i am getting the error code P2101 ( throttle actuator system malfunction). this normally happens at high rpm around 8000. as you can see from the data log the throttle plate and the throttle pedal stars to separate and this is when the error comes up. anyone could suggest what is the most likely to be the failure if its the throttle pedal, the throttle plate of the throttle actuator control module?

Things I already did:
Check wiring
Replace relay
Clean the TB
To perform the relearning procedure
Reduce the% opening TB.
Check the battery voltage
Look for leaks in admission
...................
The weekend before this failure, I did the porting of the admission. After this the problems began.

IT sounds like there is a problem with the throttle body. I would recommend trying a known working one to see if the problem goes away.

I'll try another TB J37

Last night I moved the TB adjustment screw and opened the TB. This caused the fault to occur at 7k RMP. Then, I calibrate the TB with these values.
------------
Closed 0.60 / 1.48 volts
Default position 0.85 / 1.67 volts
Open 4.00 / 4.20 volts
Closed 0.1%
Default position 7.8%
---------
The error occurred again at 8k rpm.

Today I read in this forum that the values I am using are not correct. Today I will try to adjust TB with new values and increase the Maximun plate deviation from 6% to 10%

Closed 0.60 / 1.47 volts
Default position 0.90 / 1.72 volts
Open 3.97 / 4.17 volts

please. If they have any information that will help me

Here the actions of today
Install my J37 on another civic SI. The fault did not replicate.
Install another J37 in my car. The fault persists.
In my map, increase the values of maximun plate desviation from 5% to 10%. Did not work.
Again check continuity in wiring. Everything is ok

Anything else I can check?
I will try to increase the maximun plate desviation from 10% to 50%

I recommend that you read the information posted at: https://www.hondata.com/forum/viewtopic ... ent#p90094

Read the summary on the first post:
"Bigger throttle bodies draw more current, potentially overheating the controlling circuitry, causing erratic throttle operation and errors. This cannot be fixed by software."

Hi.

Replace the TB cover with one of an OEM TB of SI. In this cover are the connectors and the TB position sensor ... The issue was solved.
