DTC P0410 Secondary Air Injection (AIR) System

Circuit Description
The PCM activates the secondary air injection system by grounding the AIR relay. This energizes the pump and the vacuum control solenoid. As vacuum is applied to the two shutoff valves, fresh air is allowed to pass through them. The AIR pump forces fresh air past the shutoff valves and into the exhaust stream in order to accelerate catalyst operation. The PCM will run up to 3 diagnostic tests using the O2S1 voltage and Short Term FT to verify system operation. The system can be diagnosed during normal secondary air injection operation or the scan tool can activate the system specifically for diagnostic purposes. If an air flow problem is detected this DTC will set. When inactive, the shutoff valve prevents air flow in either direction.

Conditions for Running the DTC
• AIR system commanded ON for more than 20 seconds.

• The IAT is between 1° C and 151° C (32° F and 302° F).

• The ECT is between 5° C and 114° C ( 41° F and 230° F).

• Battery voltage is more than 11.7 volts.

• Engine run time is more than 200 seconds.

• Calculated air flow is more than 11 gps.

• Accumulated flow between 240 cts and 600 cts.

• BLM cell of 16 or 17.

• TPS changes less than 5 percent.

• Stabilization time of more than 1 second.

• Fuel ethanol composition of less than 15 percent.

• DTCs 105, 107, 108, 112, 113, 117, 118, 122, 123, 130, 131, 132, 133, 1133, 134, 171, 172, 178, 179, 201, 202, 203, 204, 300, 336, 340, 341, 506, 507, 601, 602, and 1621 are not set.
Conditions for Setting the DTC
Lean time is more than 1 second during 4 second active test.

Action Taken When the DTC Sets
• The malfunction indicator lamp (MIL) illuminates after two ignition cycles with the malfunction present.

• The PCM records the operating conditions at the time the diagnostic fails. The Freeze Frame and Failure Records buffers stores this information.

• A history DTC is stored.

Conditions for Clearing the MIL/DTC
• The MIL will turn OFF after 3 consecutive ignition cycles in which the diagnostic runs without a fault.

• A history DTC will clear after 40 consecutive warm up cycles without a fault.

• A scan tool can clear the DTCs.

Diagnostic Aids
An intermittent may be caused by any of the following conditions:

• A poor connection

• Rubbed through wire insulation

• A broken wire inside the insulation

Thoroughly check any circuitry that is suspected of causing the intermittent complaint. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.

If a repair is necessary, refer to Wiring Repairs or Connector Repairs in Wiring Systems.

Test Description
The numbers below refer to the step numbers on the diagnostic table.

This step checks for a restriction in the engine vacuum supply to the AIR shutoff valve.

This step determines if the lack of air is caused by an open in the AIR supply hose or a defective shutoff valve.

Code po410

P0410 - Secondary Air Injection System Malfunction
Possible causes- Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

This is likely a pump problem caused by water being sucked into the secondary air injection pump under the hood.

I have a 00 cadillac deville base. i have a po410 check engine code. i was wondering what is the usually fix for this

Code po410 secondary air ignition malfunction

Start up your car cold, if you don't hear a sound like a vacuum cleaner running under your car you probably need a new air pump.
First, check the maxi-fuse in the underhood fuse block for the AIR pump.
If it's blown then you need to get under the car on the driver's side.
Remove the front cover and look at the bottom cover on the air pump, if it's dislodged and full of water the pump probably sucked up some water and is no longer good. There is a bulletin out to replace the air pump and the intake duct with a redesigned part that is not so suceptible to water intrusion. Also it's possible that the connector is burnt up, I have seen some with new air pumps set codes because of a fried electrical connection.thank you and have a wonderful day

Engine code po307 AND PO410

Hey; Code 307 is a code for misfire on cylinder #7. It could be caused by bad spark plug, ignition module. If engine has a miss then I would replace the spark plug first. If that don't fix then it will require further diagnosis with a scan tool. Code PO410 is for the secondary air injection system. Make sure the vacuum hoses going to the valves on the front and rear cylinder banks are connected and the hose(s) not damaged. Also make sure the solenoid is connected both electrical and vaccum' Maybe this will help

Engine light came on, code po410 came up.

This has to do with the secondary air pump system, this system is used at cold start-up and involves three components; air pump, solenoid valve and a relay. Many times the valve becomes stuck or clogged, the relay has also been known to fail.

Which sensor do I need to correct code po410

PO410. Secondary air pump code.

Check fuse for air pump. Blown.
Replaced the air pump if it's in Bad shape.
The air pump is only $100 (NAPA) Gotta be water in the air pump. Water gets in air pump...then rapid below freezing conditions the air pump freezes...blows fuse.....set air pump code.

There is a GM bulletin about a new intake tube for the air pump for exactly this problem. This new intake tube should save the air pump, get the new intake pipe/valve the same time you repair or replace the air pump if it's gone bad. Check the fuse first though, good luck.

P0410 Secondary Air Injection System Malfunction
I am very familiar with this failure code, you are going to have to replace the secondary air injection pump, it has a failed motor in it, the code really indicates no airflow from the pump when commanded to be on.
