Help with unusual fault in civic reborn automatic

[borgfilez]

Have this car for 1.5 years and for last 2 to 3 months having this problem.. already spent 50000+ still problem remains ...

Randomly car going to limp mode. RPM get fixed to 2000 and no acceleration works restarting car sometimes fix it for few minutes

Sometimes it starts after using car and other times right when you start car in morning.

Have changed following things in last 2 months and it fixes problem for 2 to 3 days until starts again

New plugs
New coils
Three times changed throttle body (used)
Changed the acceleration peddel after a repair try.

Still car starts either normal and goes to limp mode or start with limp mode.

ECT's can throw ecu in limp mode.
Although you can use a scanner and monitor when problem occur.

[Taimur92]

Start by scanning for codes when the car goes to limp mode then troubleshoot from there. If the car throws multiple errors when it goes into limp mode and all of that goes away on its own and comes back later, this could have something to do with the ecu wiring being shorted somewhere on its path. Trace the wiring from the ecu end for any breaks or wrong connections and check all the fuses too.

[borgfilez]

Scanner never shows any issues or code for transmission even in limp mode.
Only code i get is in limp mode is P2135

[borgfilez]

P2235 is the code everytime car in limp mode. When car start fine code goes away. Ignor the other code as it is temp and came after all this peddle change and etc.

Wiring has been checked by electrician twice with 2 different people.
Only alteration left is the starter motor that is giving extra current from battery by an electrician because it doesn't start the car else.

Now i have told each and every mechanic that this problem started after this wire but no one agrees and say it is nothing to do with it.

[Hassan1991]

You got your problem.
Have you calibrated the throttle?
Between which wire you are talking about?

[borgfilez]

Pls ignore the calibration error

[Hassan1991]

Okay, but you have to calibrate it everytime.

This seems to be your problem. I would get rid of the wire and try restoring the starter motor wiring to factory default. If the motor is weak then have it repaired but get rid of the wire.

[borgfilez]

Yeah but all Mechanic's (asked 3) are not agreeing.. says you want to change it fine ... But a mechanical part cannot give you electrical issues

[Hassan1991]

Starter is give a wire from direct battery or a wire is added to trigger signal for solenoid?

[borgfilez]

All i know is wire is connected to battery directly. Now I don't actually know pass that. I can ask if you like since car is still ar repairs.

I tried by removing cable few days back from battery just to test if rpm get fix but removing wire stops starter to work

[Hassan1991]

You didn't answered my question. You ever done recalibration after pedal or throttle body work?

[borgfilez]

Yes multiple times.. even when there was no such code.
