The electronic throttle body is an important component of any vehicle, but when it stops working correctly, you may need to relearn the system. The process can seem daunting at first, but with a few simple steps and some patience you can have your electronic throttle body up and running in no time. First, disconnect the battery for safety purposes. Next, locate your vehicle's Throttle Position Sensor (TPS) and check its wiring harnesses to make sure they are securely connected. After that, attach an OBD II scanner to the diagnostic port on your car or truck which will allow you to access information from within the engine control unit (ECU). From there, follow the instructions provided by your scanner manufacturer on how to reset or “relearn” the TPS so that it can accurately measure incoming data from the accelerator pedal. Once this step has been completed successfully, reconnect both batteries and start up your engine – if all goes well then you should be good to go! Remember though that every vehicle is different so take care not to skip any of these steps as doing so could lead to further complications down the road.
