C0327 on Cadillac
Excessive Lateral Acceleration Sensor Rate
C0327 on Cadillac vehicles indicates excessive lateral acceleration sensor rate. Au7o has documented this code across 1 Cadillac model — most commonly on Escalade ESV. 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 Cadillac range from $250 to $600, 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

Cadillac Escalade ESV(1 issue)
- Transfer Case Encoder Motor and Position Sensor Failure2002-2020
The transfer case encoder motor that controls AWD/4WD engagement fails, causing the "Service 4WD" message and preventing 4WD engagement. The position sensor inside the encoder motor sends incorrect signals. The transfer case may also develop an internal fluid leak past the front output seal.

What does C0327 mean on Cadillac?▼
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 Cadillac specifically, this code is documented across 1 model.
