C0327: Excessive Lateral Acceleration Sensor Rate
7 vehicles · 4 makes · $100-$3,000 repair
Most Reported On
C0327 is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2007-2022 GMC Sierra 3500HD, 2009-2011 Kia Borrego, and 1999-2025 Chevrolet Silverado 2500HD, plus 4 other vehicles, with repair costs ranging from $100 to $3,000.
