Q: What are the functions and locations of knock sensors on Volkswagen Passat?
A:
The two knock sensors are fitted on all models. The knock sensors are on the left side of the engine block, directly below the intake manifold, with one knock sensor being on each side of the engine block (V6 models have a knock sensor on each side of the engine block, under the intake manifold). The knock sensor detects excessive vibration, including spark knock or ping, and the knock control system is designed to decrease spark knock during heavy detonation, and the engine is able to use maximum spark advance to give it better driveability. Knock sensors generate an AC response voltage based on the strength of the knock and the signal is diverted to the ECM which delays the timing in order to avoid detonation. In order to reach the knock sensor, take out the required parts, unplug the electrical connector, unscrew the bolt, and pull out the sensor of the engine block. Installation means the undoing of the process to remove it and tightening the knock sensor bolt to 15 ft-lbs (20Nm).
