This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble checking a system that helps the car not slow down too quickly when you take your foot off the gas pedal.
The P16B3 code indicates an issue with the self-test of the Engine-Drag-Torque Control (MSR) system, which prevents the wheels from locking up when the engine suddenly loses power.
The Engine-Drag-Torque Control (MSR) system is designed to prevent excessive engine braking that can lead to wheel lockup. The control module performs self-tests to ensure the system is functioning correctly. If the self-test fails, the P16B3 code is triggered.
