DTC P0410

Secondary air injection system problem
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.
No
Record the FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILBAILITY
•  Verify related Service information availability.
•  Is any related Service information available?
Yes
Perform repair or diagnosis according to th available Service information.
No

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].)
No
Go to the next step.
4
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA
•  Is DTC P0410 on FREEZE FRAME DATA?
Yes
Go to the next step.
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”.
•  Perform the “SECONDARY AIR INJECTION CONTROL VALVE INSPECTION”.
•  Perform the “SECONDARY AIR INJECTION SOLENOID VALVE INSPECTION”.
•  Perform the “SECONDARY AIR INJECTION PUMP INSPECTION”.
•  Is there any malfunction?
Yes
Repair or replace the malfunctioning part according to the inspection results, then go to Step 8.
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.
No
Go to the next step.
7
INSPECT FOR RESTRICTION AT THE TWC
•  Visually inspect for restriction at the TWC.
•  Is there any restriction at the TWC?
Yes
Replace the TWC, then go to the next step.
(See EXHAUST SYSTEM REMOVAL/INSTALLATION [13B-MSP].)
No
Go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P0410 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the DRIVE MODE 05.
•  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].)
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [13B-MSP].)
No
DTC troubleshooting completed.
