DTC P0341 CMP SENSOR
DTC P0341 CMP SENSOR PFP:23731
Description BBS002BO
The camshaft position (CMP) sensor senses the retraction with cam-
shaft (left side) to identify a particular cylinder. The camshaft position
(CMP) sensor senses the piston position.
When the crankshaft position (CKP) sensor system becomes inoper-
ative, the camshaft position (CMP) sensor provides various controls
of engine parts instead, utilizing timing of cylinder identification sig-
nals.
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.
On Board Diagnosis Logic BBS002BP
NOTE:
If DTC P0341 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652 or
P0653. Refer to EC-1691, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
DTC Confirmation Procedure BBS002BQ
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 5 seconds.
If engine could not start, keep ignition switch at START position
for 5 seconds.
4. If DTC is detected, go to EC-1644, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine and let it idle for at least 5 seconds.
If engine could not start, keep ignition switch at START position for 5 seconds.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If DTC is detected, go to EC-1644, "
Diagnostic Procedure" .
