About B2416

B2416 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

Because B2416 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Climate Control Module monitors the position of the recirculation door actuator via an internal feedback potentiometer to confirm the door is reaching commanded outside air and recirculation positions. DTC B2416 is set when the module commands the recirculation actuator to a known position and the feedback signal does not reach the expected calibrated end stop within the allowed time, indicating the actuator travel is outside accepted limits. This can be caused by a mechanically obstructed door, a slipping or stripped actuator gear train, a faulty internal feedback potentiometer, or a wiri...
