Code B122E Chrysler Description

The B122E Chrysler diagnostic trouble code indicates that the PTS (Park Assist) sensor 7 ring time is too short. This means that the sensor responsible for detecting obstacles or objects in the vehicle's path when parking is not functioning correctly. The Park Assist system uses sensors located on the front, rear, and sides of the vehicle to alert the driver of potential obstacles and help them navigate tight parking spaces. When the sensor ring time is too short, it may result in inaccurate readings or a failure to detect obstacles, increasing the risk of collisions while parking.
