Hella Engine Knock Sensor - 6PG 013 114-571

The part number is 6PG 013 114-571.

This sensor is compatible with Dodge JOURNEY (2012-2015) MPV models equipped with 3.6L engines.

A knock sensor detects abnormal combustion vibrations (engine knock) and sends signals to the ECU. The ECU then adjusts ignition timing to prevent damage and optimize performance.

Symptoms can include a check engine light, stored trouble codes (e.g., P0325-P0334 range), reduced engine power, increased fuel consumption, and audible engine knocking or pinging.

While the sensor itself might unscrew with a standard socket, proper torque specifications are crucial. It is recommended to have it installed by a professional mechanic to ensure correct fitment and function.

This is a Piezoelectric Sensor.

This sensor has 3 pins.

This is a common symptom of a faulty knock sensor. The ECU may store error codes related to engine knock. Have the codes read by a mechanic to confirm if the knock sensor is the cause. If confirmed, replace the sensor.

A faulty knock sensor can prevent the ECU from optimizing ignition timing, leading to a loss of power. Ensure the sensor is properly connected and functioning. If the sensor is defective, replacement is necessary.

When the knock sensor is not reporting accurately, the ECU might default to less optimal timing settings, which can reduce fuel efficiency. Replacing a faulty sensor can help restore proper fuel economy.

While the sensor's job is to *prevent* knock, a malfunctioning sensor might fail to detect it, allowing the engine to knock. If you hear unusual noises, have the sensor and ignition timing checked by a professional.
