Hi, the problem is the engine light is on and while it's on I'm losing acceleration and sometimes it disappears. Some mechanic asked me to change the pedal acceleration and I've done it but I'm still facing the same problem. The codes I got are P2138, P2106, and P0198.
Maybe this is related to the problem I had changed the gear box after three days of the change. These problems show up please help me.

With these codes it looks like you have a throttle body that needs to be replaced, the last code is for engine oil temperature so I would check the oil level and change it with the filter if it has been a while since the last change.

P2138 - Throttle/Pedal Position Sensor/Switch "D"/"E" Voltage Correlation:
P2106 - Throttle Actuator Control System - Forced Limited Power:
P0198 - Engine Oil Temperature Sensor High:

Here is how to change the throttle actuator out and when you are done, please clear the codes. Check out the images (below). Let us know how it goes.

Hi Mr. Ken,

Thank you for the answer. I replaced the throttle body as you recommended, but still the engine light on and missing the acceleration. I’ve changed for now the acceleration pedal and the throttle body it didn’t work. Is this problem related to the change of the gear box or not relevant

Do you still have the codes or are they gone now? Also please upload a short video of the engine running so I can see.

So, you installed a new throttle body, correct? Did you clear the codes after? These are for the throttle body so the only other thing is the wiring needs to be checked or the PCM is bad, here is how to check the wiring and the diagrams below with the PCM replacement instructions which you can get a preprogrammed unit by searching google or Ebay.
