p2138 fault solution: Focus on inspecting the throttle body, and replace it with a new one if necessary. The P2138 fault code indicates that there is a problem with the throttle or accelerator pedal position sensor. The possible causes of this phenomenon are: 1. The throttle body itself is faulty or the accelerator pedal position sensor is not working properly; 2. A fault in the wiring related to the throttle body to the accelerator pedal position sensor. The throttle body is one of the important components of today's fuel-injected engine systems. Its upper part connects to the air filter, and the lower part connects to the engine block, serving as the throat of the car engine. Whether the car accelerates smoothly is closely related to the cleanliness of the throttle body. Cleaning the throttle body can reduce fuel consumption and make the engine more responsive and powerful.
