DescriptionINFOID:0000000005929934
The knock sensor is attached to the cylinder block.
It senses engine knocking using a piezoelectric element. A
knocking vibration from the cylinder blo ck is sensed as vibrational pressure. This pressure is converted into a
voltage signal and sent to the ECM.

P0340 CMP SENSOR (PHASE)
P0340 CMP SENSOR (PHASE)
DescriptionINFOID:0000000005929944
The camshaft position sensor (PHASE) senses the retraction of
camshaft (INT) to identify a particular cylinder. The camshaft position
sensor (PHASE) senses the piston position.
When the crankshaft position sensor (POS) system becomes inoper-
ative, the camshaft position sensor
(PHASE) provides various con-
trols of engine parts instead, utilizing timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When 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.
ECM receives the signals as shown in the figure.

If DTC P0340 is displayed with DTC P0643, first pe rform the trouble diagnosis for DTC P0643. Refer to

P0420 THREE WAY CATALYST FUNCTION
DTC LogicINFOID:0000000005929949
DTC DETECTION LOGIC
The ECM monitors the switching frequency ratio of air fuel ratio (A/F)
sensor 1 and heated oxygen sensor 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of A/F sensor 1 and heated oxygen sensor
2 approaches a specified limit value, the three way catalyst (mani-
fold) malfunction is diagnosed.
DTC CONFIRMATION PROCEDURE
