DTC P0325: Knock Sensor Circuit Malfunction: DTC Detecting Condition
- DTC Description, the ECM monitors the range of the analog input signal from knock sensor 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 P0325 is set. In case the noise level is higher than the upper threshold or lower than the lower threshold, the DTC P0325 is set too. If same error code is set in the next driving cycle, the ECM illuminates the MIL.
