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.

If you follow the hose from the pump it should go to a valve and tube that connects to the exhaust.
Depending on the trouble code, you may need the check valve on the end of that tube.

Diagnostic Test Code (DTC) P0410 indicates that your secondary air injection system is not functioning properly.
Not all 2001 Chevrolet Bazers are equipped with secondary air injection. The secondary air injection system was added to vehicles that were to be sold in certain areas where the emissions laws required it, like the State Of California.

The Powertrain Control Module (PCM) monitors the system by commanding the secondary air blower motor to run and the air injection solenoid to open. This causes additional oxygen to enter the exhaust system. The PCM then monitors the signal from the oxygen sensors to see if the commanded air has in fact, entered the exhaust system. Code P0410 sets when the PCM has commanded the blower motor on and the solenoid open and there is little or no change in the oxygen sensor signal.

GM has had some problems with these systems and there has been a Technical Service Bulletin (TSB) issued that addresses some of the known concers. Below is a brief description of the TSB and the issues involved.

Bulletin No.: 04-06-04-015A
Date: November 28, 2006
TECHNICAL
Subject:
LN2, L43 or L35 Engine SES/MIL Light Illuminated, AIR Pump Ingesting Water and DTC P0410 Set (Replace AIR Pump and Inlet Hose Assembly)
Models:
1999-2003 Chevrolet Blazer, S10
1999-2001 GMC Jimmy
1999-2003 GMC Sonoma
1999-2001 Oldsmobile Bravada
with Vortec 2.2L I4 or 4.3L V6 Engine (VINs 4, 5, W - RPOs LN2, L43, L35)
Condition
Some customers may comment on the SES/MIL light being illuminated. Upon investigation, the technician may find a DTC P0410 indicating that there is a concern in the secondary air injection system.
Cause
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.
Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly...

The bulletin goes on and gives detailed information on how to perform the repair and the part numbers of the replacement parts needed to do so. Your local dealer can provide the parts for you and you can probably get them to print out a complete copy of the bulletin for you. It is not really hard to do if you want to do this yourself.

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

your vehicle has an air pump that puts air in to the exhaust cooling it to reduce nox gasses most likely the pump has sucked up water shorting it out and blowing the fuse. there is an updated pump inlet and pump to fix this problem also need to replace the fuse after replacing pump.

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.

If you have a "Air pump installed on your TB then you need to replace pump and or check to make sure that the hose's are all connect to it prior to replacing the pump which is dependisng on which engine you have on the lower left side (passenger)
Models Affected
1999-2003 Chevrolet Blazer, S10
1999-2001 GMC Jimmy
1999-2003 GMC Sonoma
1999-2001 Oldsmobile Bravada
All with 2.2L or 4.3L Engine (VINs 4, H, 5, W -- RPOs LN2, L43, L35)
Condition
Some owners may comment on the check engine light being illuminated. Upon
investigation, the technician may find a DTC P0410 indicating there is a concern in the
secondary air injection system.
Cause
This concern may be attributed to water that may have collected in the AIR pump or the
vent solenoid and frozen or corroded the pump.
Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly using
the following procedure:
1. Prep vehicle.
2. Raise vehicle on hoist.
3. Remove shield covering AIR pump.
4. Remove hose and vacuum lines from pump and solenoid.
5. Remove AIR pump inlet hose. Do not re-use.
6. Disconnect electrical connectors from pump and solenoid.
7. Remove pump mounting bolts and pump.
8. Transfer isolators from the old pump to the new pump.
9. Install new AIR pump and bolts to vehicle. Tighten the bolts to 17N·m (12.5 lb ft).
10. Route new hose assembly up between engine and fender. It should come up near
the area between the battery and the coolant bottle.
11. Connect new inlet hose to pump inlet.
12. Connect old outlet hose to pump outlet.
13. Connect electrical connector to pump.
14. Connect electrical connector for solenoid to connector on the new hose assembly.
15. Connect the hose with the white nipple to the vacuum source hose.
16. Connect the remaining hose to the shut off valve.
17. Install shield covering AIR pump.
18. Lower vehicle.
19. Remove coolant reservoir nut nearest the battery.
20. Route new hose assembly between the battery and the coolant reservoir with the solenoid on top.
21. Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut
back into the vehicle.
22. Use a wire tie to keep the new hose assembly away from the engine. On four
cylinder engines, tie to the AIR outlet hose. On six cylinder engines, tie to an
available hole in the radiator fan shroud.
