C0219 Code: Meaning, Causes, and Symptoms | OBD2 Codes

C0219 – Longitudinal Accelerometer Signal Voltage

 

C0219 Possible Symptoms

 

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

 

C0219 Possible Causes

 

Faulty Electronic Brake Control Module (EBCM),Electronic Brake Control Module (EBCM) harness is open or shorted,Electronic Brake Control Module (EBCM) circuit poor electrical connection

 

C0219 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.
