DescriptionINFOID:0000000003856619
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 ECM.

P0335 CKP SENSOR (POS)
P0335 CKP SENSOR (POS)
DescriptionINFOID:0000000003856623
The crankshaft position sensor (POS) is located on the oil pan facing
the gear teeth (cogs) of the signal plate. It detects the fluctuation of
the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.
