DTC codes / C05xx · Brakes, steering and suspension / C051E
C051E indicates that the multi-axis acceleration sensor module A, which measures vehicle motion in multiple directions for stability and safety systems, is sending an intermittent or erratic signal to the control module. The computer has detected that the sensor's output is not consistent, dropping out or jumping in a way that does not match expected values under the current driving conditions.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
