DTC Description
WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
The PCM monitors the range of the analog input signal from Knock Sensor (KS) to check sensor failure that is short circuit or open circuit. If the difference between knock signal and noise level is smaller than the threshold during defined time period, the DTC P0326-00 is set. P0326-00 will also be set if the noise value exceeds the minimum or maximum thresholds.
