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.

No, it does not have a IAC, Confirmed with the Dealer. This is for the 2.0 GAS but it does have a Secondary Air Pump and a Secondary Air Pump Control Valve.

The Major problem with the 2001 Jetta GAS is the Mass Airflow Sensor.......

The TDI is a Turbo Diesel and is not a 2.0

Well, the secondary air intake malfunction has to do with the air pump I read. Water can get into the air pump in some models and the pump would have to be replaced. However, I have heard that some OEM pumps have a short hose that accumulates water sometimes, causing a recurring problem.

Also, there is sometimes a 20 or 30 Amps fuse that controls the pump.

However, I think, that even though they cleared the code at Advance Auto Parts, and it wouldn't start, that the no start condition is not related to the air pump problem, since the air pump problem is more of an emission control to reduce pollution and doesn't feed directly into the combusiton chamber.

I think that you should check the fuel injectors to make sure that they are working. They should click when under pressure with fuel, and allow fuel to enter the combustion chamber.

Maybe check the fuse for the FI or fuel injectors.

It seems like your vehicle is getting spark since it runs briefly when you spray brake cleaner into the air intake.

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.

Hey guy I had the same problem with my 2001 Yukon XL. I took it to the dealer and they charged me an arm and a leg for a diag which found nothing. I had the fuel filter changed which fixed the problem for a few months but the problem came back. I have a new car now and drive that most of the time. I came across a site and this guy said to clean the Throttle Body like this link says, http://www.youtube.com/watch?v=MnWiOrnVk28a and also clean the mass air flow sensor as this link says, http://www.youtube.com/watch?v=vPT8rL0noYg I also changed out the air filter. Fixed my problem, the engine no longer stalls and that idle flux has stopped also. I hope this helps you and anyone else who is having this problem.

please rate me solved...thanks

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.

Had one changed on my daughters 1998 VW Beetle, cost nearly $650 for part plus installation. Failure came while her car was in Boston so I was unable to complete the task. The part is readily accessible in the front of the engine compartment, and not all that difficult to replace. If you can change brakes, alternators, serpentine belts, etc. you should be able to change the secondary air pump. Check with your local parts supplier like AutoZone or Murrays, they may have tips & tricks to make the job a bit easier.

Good luck, and have confidence.
