P0420 THREE WAY CATALYST FUNCTION

DTC Description

INFOID:0000000010702967

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 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.

POSSIBLE CAUSE

• Three way catalyst (manifold)
• Exhaust tube
• Intake air leaks
• Exhaust air leaks
• Fuel injector
• Fuel injector leaks
• Spark plug
• Improper ignition timing

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
TESTING CONDITION:
Do not hold engine speed for more than the specified minutes below.
1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

Will CONSULT be used?

YES

>> GO TO 2.

NO

>> GO TO 5.

2.

PERFORM DTC CONFIRMATION PROCEDURE-1

With CONSULT

1.

Turn ignition switch ON and select “DATA MONITOR” mode of “ENGINE” using CONSULT.

2.

Start engine and warm it up to the normal operating temperature.

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.

Check 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).

P0420 THREE WAY CATALYST FUNCTION

7.

Open engine hood.

8.

Select “DTC & SRT CONFIRMATION” then “SRT WORK SUPPORT” mode of “ENGINE” using CON-
SULT.

9.

Rev engine up to 2,000 to 3,000 rpm and hold it for 3 consecutive minutes then release the accelerator
pedal completely.

10. Check the indication of “CATALYST”.

Which is displayed on CONSULT screen?

CMPLT >> GO TO 4.
INCMP >> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE-2

1.

Wait 5 seconds at idle.

2.

Rev engine up to 2,000 to 3,000 rpm and maintain it until “INCMP” of “CATALYST” changes to “CMPLT”.
NOTE:
It will take approximately 5 minutes.
If “CMPLT” is not displayed after 5 minutes, turn ignition switch OFF and cool down the engine. Retry from
step 1 when “COOLAN TEMP/S” indication reaches to 70

°

C (158

°

F).

Does the indication change to “CMPLT”

YES

>> GO TO 4.

NO

>> GO TO 2.

4.

PERFORM DTC CONFIRMATION PROCEDURE-3

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Proceed to 

ECM-272, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

5.

PERFORM COMPONENT FUNCTION CHECK

Without CONSULT

NOTE:
Use component function check to check the overall function of the three way catalyst (manifold). During this
check, a 1st trip DTC might not be confirmed.
1.

Start engine and warm it up to the normal operating temperature.

2.

Turn ignition switch OFF and wait at least 10 seconds.

3.

Restart engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no
load.

4.

Let engine idle for 1 minute.

5.

Open engine hood.

6.

Check the voltage between ECM harness connector terminals as per the following condition.

Is the inspection result normal?

YES-1 >> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

YES-2 >> Confirmation after repair: INSPECTION END
NO

>> Proceed to 

ECM-272, "Diagnosis Procedure"

.
