C0216 Code: Meaning, Causes, and Symptoms | OBD2 Codes

C0216 – Lateral Accelerometer Signals


C0216 Possible Symptoms


Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)


C0216 Possible Causes


Faulty Yaw Rate Sensor/Lateral Accelerometer,Yaw Rate Sensor/Lateral Accelerometer harness is open or shorted,Yaw Rate Sensor/Lateral Accelerometer circuit poor electrical connection


C0216 Description


The Vehicle Stability Enhancement System (VSES) is activated when the Electronic Brake Control Module (EBCM) determines that the desired yaw rate does not match the actual yaw rate. The desired yaw rate is calculated from the measured steering wheel position, vehicle speed, and lateral acceleration. With no sensor bias present, a volt signal from these sensors is interpreted by the EBCM respectively as follows: – Zero yaw rate. – Zero lateral acceleration. – Zero longitudinal acceleration. The sensor bias compensates, during VSES initialization, for sensor mounting alignment errors, electronic signal errors, temperature changes, and manufacturing differences.
