DTC P0340 CMP SENSOR (PHASE)
DTC P0340 CMP SENSOR (PHASE)
Component DescriptionINFOID:0000000001702808
The camshaft position sensor (PHASE) senses the protrusion 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 inoperative, the camshaft
position sensor (PHASE) provides various controls of engine parts
instead, utilizing timing of cylinder identification signals. The sensor
consists of a permanent magnet and Hall IC. When engine is run-
ning, the high and low parts of the teeth cause the gap with the sen-
sor 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.

DTC P0420 THREE WAY CATALYST FUNCTION
DTC P0420 THREE WAY CATALYST FUNCTION
On Board Diagnosis LogicINFOID:0000000001702816
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 air fuel ratio (A/F) sensor 1 and heated
oxygen sensor 2 approaches a specified limit value, the three way
catalyst (manifold) malfunction is diagnosed.
DTC Confirmation ProcedureINFOID:0000000001702817
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
TESTING CONDITION:
Do not hold engine speed for more than the specified minutes below.
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and warm it up to the normal operating tempera-
ture.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Start engine and keep the engine speed between 3,500 and
4,000 rpm for at least 1 minute under no load.
5. Let engine idle for 1 minute.
6. Make sure that “COOLAN TEMP/S” indicates more than 70°C
(158°F).
If not, warm up engine and go to next step when “COOLAN
TEMP/S” indication reaches to 70°C (158°F).
7. Open engine hood.

8. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUP-
PORT” mode with CONSULT-II.
9. Rev engine up to 2,000 to 3,000 rpm and hold it for 3 consecu-
tive minutes then release the accelerator pedal completely.
If “INCMP” of “CATALYST” changed to “CMPLT”, go to step 12.
10. Wait 5 seconds at idle.
11. Rev engine up to 2,000 to 3,000 rpm and maintain it until
“INCMP” of “CATALYST” changes to “CMPLT” (It will take
approximately 5 minutes).
If not “CMPLT”, stop engine and cool it down to less than 70°C
(158°F) and then retest from step 1.
12. Select “SELF-DIAG RESULTS” mode with CONSULT-II.
13. Confirm that 1st trip DTC is not detected.

Overall Function CheckINFOID:0000000001702818
Use this procedure to check the overall function of the three way catalyst (manifold). During this check, a 1st
trip DTC might not be confirmed.
