Code P0722 KIA Description

The P0722 code for KIA vehicles indicates that there is no signal being detected from the output speed sensor. The output speed sensor is a crucial component in the vehicle's transmission system that monitors the speed of the output shaft and sends this information to the engine control module (ECM). This data is used by the ECM to calculate shift points, optimize fuel efficiency, and ensure smooth operation of the transmission.

  • Note that when this occurs most cars will go into a "limp" mode. This is to protect the transmission. To the driver it feels like you are taking off from second gear. Each time you turn the car on/off limp mode is reset. In my case, only after turning the car on, it would shift out of 1st with a thud at around 30mph's. From that point on it would not "thud" but the car would lose 70% of it's power. Turning the car on/off repeats this cycle.
