P1326Knock Sensor Detection System: possible connecting-rod bearing wear
- Hyundai/Kia code · Engine
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- Engines with the Knock Sensor Detection System (KSDS) software listen with the knock sensor for the vibration that early connecting-rod bearing wear makes. When they hear it, the check-engine light flashes and the engine goes into limp mode to protect itself. Stop driving soon and have a dealer check it: Hyundai/Kia cover this under campaigns and extended warranties on many Theta, Nu and Gamma GDI engines. Not every 2010-2016 model has KSDS.
