C0327 on Chevrolet
Excessive Lateral Acceleration Sensor Rate
C0327 on Chevrolet vehicles indicates excessive lateral acceleration sensor rate. Au7o has documented this code across 2 Chevrolet models — most commonly on Silverado 1500, Silverado 2500HD. This chassis code means the stability/traction control system has detected an excessive or abnormal rate of change from the lateral acceleration sensor, which measures sideways g-forces during cornering. This sensor helps the electronic stability control (ESC) and ABS systems know how the vehicle is actually moving so they can intervene if it starts to skid. When the sensor's signal changes too fast, sticks, or reads implausibly, the computer flags it and may disable stability/traction control, often lighting the ESC, ABS, or traction warning lamps. Causes are usually a faulty sensor, its wiring, or a mounting/calibration problem. Typical repair costs on Chevrolet range from $100 to $1,200, depending on the specific model and root cause.
Common Causes of C0327
- •Faulty lateral acceleration (yaw/g) sensor
- •Loose or improperly mounted sensor (vibration/movement)
- •Damaged, corroded, or loose sensor wiring/connector
- •Sensor out of calibration after suspension/alignment work
- •Faulty steering angle or yaw rate sensor affecting the system
- •Poor ground or low system voltage
- •Faulty ABS/stability control module
C0327 on Chevrolet by Model
Chevrolet Silverado 1500(1 issue)
- Transfer Case Encoder Motor / Position Sensor Failure Causing Stuck 4WD or Service 4WD Message2000-2013
Silverado 1500 trucks equipped with electronic shift transfer cases commonly develop failures in the transfer case encoder motor, mode position sensor, or related switch/module circuitry. Owners report the truck getting stuck in 2HI, 4HI, or 4LO, flashing selector lights, or displaying a Service 4WD message. GM service information and large numbers of owner complaints/forum reports document the issue across both GMT800 and GMT900 trucks.
Chevrolet Silverado 2500HD(1 issue)
- Transfer Case Encoder Motor Failure1999-2025
The transfer case encoder motor on the Silverado 2500HD (NP246/NP261/NP263 transfer cases) fails, preventing the vehicle from shifting between 2WD, 4WD High, and 4WD Low. The encoder motor is mounted on the outside of the transfer case and uses an electric motor with a position sensor to actuate the shift fork. Moisture ingress, corrosion, and worn motor brushes cause intermittent or complete failure. The "Service 4WD" message appears on the DIC, and the transfer case may get stuck in one mode. Failure is more common in salt-belt states.

What does C0327 mean on Chevrolet?▼
C0327 stands for "Excessive Lateral Acceleration Sensor Rate." This chassis code means the stability/traction control system has detected an excessive or abnormal rate of change from the lateral acceleration sensor, which measures sideways g-forces during cornering. This sensor helps the electronic stability control (ESC) and ABS systems know how the vehicle is actually moving so they can intervene if it starts to skid. When the sensor's signal changes too fast, sticks, or reads implausibly, the computer flags it and may disable stability/traction control, often lighting the ESC, ABS, or traction warning lamps. Causes are usually a faulty sensor, its wiring, or a mounting/calibration problem. On Chevrolet specifically, this code is documented across 2 models.
