Output speed sensor

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your car. If your Elantra isn't going into drive, the output speed sensor could play a role. This sensor monitors the speed of the transmission's output shaft and helps regulate shifting. If faulty or damaged, the car may struggle to move or engage gears properly. Since the problem worsens when the engine is warm, this points to a potential internal transmission or electrical issue that may need further diagnosis at a trusted repair shop. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
