P0328 Knock Sensor 1 Circuit High
P0328 OBD Code Description:

OBD2 Code P0328 Definition:
The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM). Symptoms

Possible sumptoms of P0328
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power Possible Causes

Possible causes of P0328
– Knock sensor circuit short to GND. – Knock sensor circuit short to PWR. – Knock sensor circuit open. – Damaged knock sensor. – Powertrain Control Module (PCM The Error code is generally activated on detection of the following conditions: – An excessively high voltage from the sensor is sent to Powertrain Control Module (PCM) or Electronic Control Module (ECM) Possible Solutions

– Repair or resecure harness or connector – Replaced knock sensor
