P0327Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor)

The knock sensor on bank 1 (or the only sensor) is sending a signal voltage that is too low. The engine computer uses this sensor to detect engine knock and trim ignition timing. A low or missing signal means the computer can no longer trust knock detection, so it usually retards timing to stay safe.

Ամենատարածված պատճառներն են՝ Faulty knock sensor, Short to ground in the signal circuit, Open or high resistance in the sensor wiring, Corroded or loose sensor connector, Poor ground connection, Faulty engine control module (rare)։

Սովորաբար անվտանգ է կարճ տարածությունների վրա վարել, սակայն շուտով ստուգել տվեք։

Short-distance driving is generally fine, but get it checked soon so you do not lose power and economy long term. A technician will measure the sensor and inspect its wiring and connector for opens, shorts, or corrosion. Replace the sensor only after wiring is ruled out.
