How do you replace the knock sensor on Dodge Neon?

Disconnect the negative battery cable and raise the vehicle, securing it on jackstands. The knock sensor is located on the engine block near the starter motor, with 2000 through 2002 models having it screwed into the block, while 2003 models have it bolted. Disconnect the electrical connector from the knock sensor, then for 2000 through 2002 models, unscrew the sensor using a deep socket, and for 2003 models, remove the retaining bolt. Installation is the reverse of removal, ensuring to tighten the knock sensor for 2000 through 2002 models or the knock sensor bolt for 2003 models to the specified torque.

Dodge Neon Knock Sensor

The Dodge Neon is equipped with a Knock Sensor, which is used in maintaining the optimal performance of the engine as it identifies when knock is present and it is normally occasioned by incorrect ignition timing. This device communicates with the powertrain control module (PCM), which in turn alters the ignition timing in order to prevent detonation that is way beyond the normal course of the combustion cycle. Normally, the knock sensor used in the Dodge Neon is piezoelectric, which directly vibratory pressure peaks to detect the knocking sound and monitor it continuously. When knock is sensed, the PCM reduces the ignition timing step by step until normal combustion is achieved while timing is gradually enriched after that. This mechanism also makes sure that the Dodge Neon runs smoothly on lower octane fuel, at the same time warding off any potential harm to the engine.
