A lack of power may develop, accompanied by an illuminated Check Engine Light with fault code P2106 stored in the powertrain control module (PCM). This fault can be caused by a throttle actuator which has only limited movement. The correction for this condition includes replacing the throttle actuator and updating the PCM software.

This is my third time on this, the first time it was replaced. Second they could not find a problem and replace it the third time
check engine light on and lock of power. My mechanic is not sure if this problem is caused by throttle position sensor or whole throttle body. Suzuki dealership advise to replace the body but it cost $550 with labor. (lot of money!) Do I need to buy the body or just the sensor.

check engine light on replaced foot pedal assembly reset codes, light back on. every test showed it was the foot pedal sensor. it also showed a dealership code that the auto zone, and advance diagnostic testers couldnt look into. this leads me to believe u r stuck having to take it to the dealership and pay 90 dollars to have it diagnosed again and pay them the labor to fix it because no one else has a machine like the one they have to read deeper into the problem. it sounds like a racket to me.
