DTC P0411/16795: SECONDARY AIR SYSTEM - INCORRECT FLOW DETECTED
Test Requirements
Ensure all fuses are okay, battery voltage is at least 11.5 volts, all electrical accessories are off, A/C is off.
Ensure engine is mechanically sound.
Test Procedure

NOTE
Secondary air system is activated by ECM and blows air into exhaust pipe
upstream of catalytic converter for 100 seconds during a cold start, 41-91°F (5-
33°C). Engine must be cold to perform following test procedure.

1. Ensure fuse and secondary fuse (secondary fuse is 40 amp and is located in fuse holder on top of battery)
are okay. Check hoses and components of Secondary Air Injection System, for damage, loose fit and
improper installation, check vacuum hoses for Secondary Air Injection System. Repair as necessary.
Erase DTC memory. Verify repair. If DTC does not reset, test is complete. Perform ECM relearn
procedure. See TEST DRIVE RELEARN PROCEDURE .
2. Remove engine cover. Disconnect pressure hose from Secondary Air Pump Motor (V101), by pressing
buttons on hose connector. See Fig. 33 . Using scan tool, check Secondary Air Pump Motor (V101) in
scan tool Output Diagnostic Test Mode (Secondary Air Pump Relay activation mode). See OUTPUT
DIAGNOSTIC TEST MODE .
3. Secondary Air Pump Motor (V101) should run in intervals and air should exit pump at hose connection.
If Secondary Air Pump Motor (V101) is okay, go to step 7 . If motor runs and no air exits secondary air
pump motor, replace faulty Secondary Air Pump Motor (V101). Erase DTC memory. Verify repair. Test
is complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE . If
secondary air pump motor does not run, go to next step.
4. Disconnect Secondary Air Pump Motor (V101) harness connector, install LED test light at secondary air
pump harness connector terminals. Turn ignition on. Using scan tool, activate Secondary Air Pump Motor
(V101) in scan tool Output Diagnostic Test Mode (Secondary Air Pump Relay activation mode). See
OUTPUT DIAGNOSTIC TEST MODE . LED test light at Secondary Air Pump Motor (V101) harness
connector should flash. If LED test light at Secondary Air Pump Motor (V101) harness connector does
not flash, go to next step. If LED test light at Secondary Air Pump Motor (V101) harness connector
flashes, replace faulty Secondary Air Pump Motor (V101). Erase DTC memory. Verify repair. Test is
complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .
5. Using DVOM check resistance of Secondary Air Pump Motor (V101) wiring. See appropriate WIRING
DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS. Resistance should
be a maximum of 1.5 ohms for each reading. Check wiring for short circuit to one another in Secondary
Air Pump Motor (N101) harness connector. Repair as necessary. Erase DTC memory. Verify repair. Test
is complete. Perform ECM relearn procedure.
Secondary Air Pump Motor (N101) wiring is okay, go to next step.
6. Check Secondary Air Pump Relay (J299) and Secondary Air Pump Relay (J299) wiring. See DTC
P0418/16802: SECONDARY AIR PUMP RELAY (J299), MALFUNCTION . Repair or replace as
necessary. Erase DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure. See
TEST DRIVE RELEARN PROCEDURE .
7. Disconnect vacuum hose from Secondary Air Injection Valve (N112) and disconnect pressure hose from
secondary air pump motor, press buttons on pressure hose connector to disconnect pressure hose. See Fig.
34 . Blow lightly into disconnected pressure hose, Combi-Valve should be closed. Connect hand vacuum
pump to disconnected vacuum hose and apply vacuum to Combi-Valve, Combi-Valve should open. If
Combi-Valve opens when vacuum is applied, Combi-Valve is okay. Go to next step. If Combi-Valve
does not open when vacuum is applied, replace faulty Combi-Valve. Erase DTC memory. Verify repair.
Test is complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .
8. Check Secondary Air Injection Valve (N112). See DTC P0412/16796: SECONDARY AIR
INJECTION VALVE (N112), ELECTRICAL CIRCUIT MALFUNCTION . Repair as necessary.
Erase DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure.
NOTE: Do not use compressed air to check Combi-Valve.

SOURCE: Read a PO410 code,1996 850 GLT volvo, secondary

The most common cause is either a bad air pump (under your battery tray) and/or a bad SAS check valve which is connected in to your exhaust next to the firewall in the engine compartment.  It could also be a bad relay for the motor.  Less common, but possible, other bad components are the vacuum solenoid that controls the SAS valve, which is located by the radiator or a broken/leaking vacuum line to or from the solenoid.

You can test the motor by jumping the relay or applying 12v straight to it.  If the motor runs it most likely is not the problem.  If not, it's likely that there is water in it and you should replace both the motor and SAS valve.  The SAS valve is a pain to get unbolted, at least on turbo cars.  You can check the solenoid by just making sure there is vacuum going to the SAS valve a few seconds after starting up the car cold, and checking the lines for any obvious wear in the rubber elbows or breaks in the plastic line.

I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check


here is what i found on p1416.



P1416 Chevrolet
P1416 Chevrolet - Secondary Air Injection System Bank 2
Possible causes
- Faulty Secondary Air Injection (AIR) pump
- Secondary Air Injection check valve bank 2
- Secondary Air Injection (AIR) pump electrical circuit fault
- Blocked Secondary Air Injection (AIR) system

When is the code detected?

The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).


Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)


P1416 Chevrolet Description
An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

P2440 refers to the Secondary Air Injection system. It means that the switching valve is stuck open. We already replaced the secondary air flow pump, now it's telling us that's its the secondary air flow sensor and the valve is stuck open. the code is coming up P2440

410 CODE TRAILBLAZER i6 MOTOR


Definition
Secondary Air Injection System fault
Explanation
The air injection system is monitored for faults
Probable Causes
1) Circuit relay defective or fuse open
2) Check connector and wiring
3) AIR pump defective or hoses blocked

You have an air injection problem with the emissions system, check with a tech for any tsb's or recall extended warranty etc that are related to that system. CHECK WARRANTY!

It can be caused by...
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.
Blown AIR pump fuse due to freezing up.

Possible solutions:
The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose.
Replace the AIR pump AND one-way check valve.
Test and clean the AIR pump AND test and replace the one-way air check valve.
Replace the AIR pump inlet hose.
Replace the AIR pump fuse (found under the hood).

You might have to replace a hose or two, or you might need an entire new air pump. A visual inspection from a licensed mechanic will confirm exactly what needs to be replaced, as it can be one of several things, if not multiple problems.

Hope that helps.
