Hyundai Sonata no response when pressing gas pedal, possible throttle position sensor issue on Hyundai Sonata

Some Hyundai Sonata owners report experiencing issues with their vehicle not responding when pressing the gas pedal, which may be caused by a faulty throttle position sensor (TPS). These owners note that a malfunctioning TPS can lead to incorrect data being relayed to the engine control module (ECM), resulting in poor fuel economy and performance issues. Common symptoms include poor acceleration, rough idling, and engine stalling. To diagnose the problem, some owners recommend testing the throttle position sensor, and if it is found to be defective, it may need replacement. The average cost for replacing a throttle position sensor in a Hyundai Sonata typically ranges from $157 to $198. It is advisable for owners experiencing these issues to have the TPS checked by a qualified mechanic to ensure proper vehicle functionality.
