P0340 CMP SENSOR (PHASE)
P0340 CMP SENSOR (PHASE)
DescriptionINFOID:0000000001693299
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 P1129, first perform the trouble diagnosis for DTC P1129. Refer to

P1121 ELECTRIC THROTTLE CONTROL ACTUATOR
DescriptionINFOID:0000000001693324
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valve position, and the opening and closing speed of the throt-
tle valve and feeds the voltage signals to the ECM. The ECM judges the current opening angle of the throttle
valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening
angle properly in response to driving condition.
