DTC P0410, P0411 [13B-MSP]

DTC REFERENCE CHART

DTC P0410
DTC P0411

Secondary air injection system problem
Secondary air injection system incorrect upstream flow

DETECTION CONDITION

The PCM monitors the A/F sensor output current when the secondary air injection system is operating. If the output current is less than the specification, the PCM determines that there is a secondary air injection system problem.

Diagnostic support note

This is an intermittent monitor (AIR system.)
The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
FREEZE FRAME DATA is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Secondary air injection system malfunction
- Air system malfunction
- Secondary air injection control valve malfunction
- Secondary air injection solenoid valve malfunction
- Secondary air injection pump malfunction
Restrict or damaged in exhaust system
Restrict in TWC
PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAVE BEEN RECORDED Have FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS (AIR system related) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE OR STORED DTC Turn the ignition switch off, then ON position (engine off.) Verify the related PENDING CODE or stored DTCs using M-MDS. Is other DTC present?	Yes	Go to appropriate DTC troubleshooting procedure. (See DTC TABLE [13B-MSP] .)
3		No	Go to the next step.
4	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA Is DTC P0410 or P0411 on FREEZE FRAME DATA?	Yes	Go to the next step.
4		No	Go to troubleshooting for DTC on FREEZE FRAME DATA. (See DTC TABLE [13B-MSP] .)
5	INSPECT SECONDARY AIR INJECTION SYSTEM OPERATION Perform the "AIR System Inspection". (See ENGINE CONTROL SYSTEM OPERATION INSPECTION [13B-MSP] .) Perform the "SECONDARY AIR INJECTION CONTROL VALVE INSPECTION". (See SECONDARY AIR INJECTION (AIR) CONTROL VALVE INSPECTION [13B-MSP] .) Perform the "SECONDARY AIR INJECTION SOLENOID VALVE INSPECTION". (See SECONDARY AIR INJECTION (AIR) SOLENOID VALVE INSPECTION [13B-MSP] .) Perform the "SECONDARY AIR INJECTION PUMP INSPECTION". (See SECONDARY AIR INJECTION (AIR) PUMP INSPECTION [13B-MSP] .) Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results, then go to Step 8.
5		No	Go to the next step.
6	VISUALLY INSPECT THE EXHAUST SYSTEM PARTS Is there any deformed exhaust system part?	Yes	Replace the suspected part, then go to Step 8.
6		No	Go to the next step.
7	INSPECT FOR RESTRICTION AT THE TWC Visually inspect for restriction at the TWC. (See THREE-WAY CATALYTIC CONVERTER (TWC) INSPECTION [13B-MSP] .) Is there any restriction at the TWC?	Yes	Replace the TWC, then go to the next step. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [13B-MSP] .)
7		No	Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0410 OR P0411 COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. Perform the DRIVE MODE 5. (See OBD-II DRIVE MODE [13B-MSP] .) Is the PENDING CODE same as the DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [13B-MSP] .)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [13B-MSP] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [13B-MSP] .)
9		No	DTC troubleshooting completed.
