DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the air fuel
ratio (A/F) sensor 1. The oxy-
gen storage capacity of the three way catalyst (manifold) causes the
longer switching time. To judge the malfunctions of heated oxygen
sensor 2, ECM monitors whether the switching response of the sen-
sor's voltage is faster than specified during the various driving condi-
tion such as fuel cut.
DTC CONFIRMATION PROCEDURE

P0420 THREE WAY CATALYST FUNCTION
DTC LogicINFOID:0000000012431487
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.

AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation:
• Front wiper (LO, HI)
• Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan
Operation Procedure
NOTE:
Never perform auto active test in the following conditions:
• Passenger door is open
• CONSULT is connected
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
• When auto active test has to be cancelled halfw ay through test, turn the ignition switch OFF.
• When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-98,
"ComponentFunctionCheck" (with Intelligent Key system) or DLK-232, "ComponentFunctionCheck"
(without Intelligent Key system).
