Probably the secondary air injection solenoid valve is stuck, this usually happens when moisture gets inside it.

SOURCE: 2005 GMC Envoy 4wd 4.2liter V6 check engine light is on.

The check valve is #12619128 and the gasket is #24577193. I think $65 and $75 respectively you can try websites like parts4chevy.com and gmpartsdirect.com. 
your talking about the diverter valve for the AIR pump. In which case it is easy to do and its easily accesible in the engine bay. The valve is located at the passenger side by the transmission dipstick tube under the intake tube. Good luck

SOURCE: engine light stays on all the time

Before you start replacing parts and wasting money make sure and get the codes checked.If you just replace a part cause someone told you this could be the problem you can spend a lot of money and not get the problem fixed.Get the codes and then post back and I`ll be glad to help you find the problem.You can get them checked free at most parts stores.They might try to sell you a part for that code.Be patient and post back with the code and I`ll be glad to help.Good luck.

SOURCE: 2006 GMC Envoy I6 HVAC fan stopped working. Level

If high speed went out first, then it is the switch.
There is the most arcing in the switch at high speed.
If there was motor or relay trouble, it would effect all speeds.
If there were problems with the ballast resistor, it would effect lower speeds.

SOURCE: 1. Trouble Code #00410 "States

I have a 2000 2.2L Sonoma that I had to replace the motor in with a 99 engine and when I did the exhaust manifold was different and I could not hook up my air pump and I now have a service engine light on all the time but it runs just fine and I even think it improved my gas mileage. You might check your air pump connections or sensor. The air pump is on the front of the engine below the ac unit. I TOO have a Hanes book but also a Chilton book because 1 covers some things the other does not

My 2008 Trailblazer has OBD-II code P2430. How do I replace the secondary air injection pump?


This code doesn't mean to replace the air pump ,
DTC P2430 : Secondary Air Injection (AIR) System Pressure Sensor Circuit
Circuit/System Description
The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. An electric air pump, the secondary AIR injection pump, provides filtered air on demand to the AIR control solenoid valve/pressure sensor assembly. The AIR control solenoid valve/pressure sensor assembly controls the flow of air from the AIR pump to the exhaust manifold. The AIR solenoid relay supplies the current needed to operate the AIR control solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The engine control module (ECM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.
This is a pressure sensor problem . What this video on testing !

What does code p0411 on 2008 Envoy


Diagnostic Test Code (DTC) P0411 is defined by SAE J2012 as "Secondary Air Injection System Incorrect Flow Detected"

This DTC runs when the air injection pump and the air injection control solenoid do not have any detectible electrical faults. The PCM commands the pump to run and the solenoid to open and add forced air to the exhaust stream. The PCM then looks at the oxygen sensors in the exhaust to see if there is added oxygen in the exhaust as expected. If the oxygen sensors do not indicate that added oxygen is present, DTCP0411 sets.

There is also an air pressure sensor involved in this system, but I have never replaced one of these...failure is rare.

With all that said, I have replaced MANY air injection control solenoids to fix this fault. I have also replaced a couple pump motors, but not nearly as many as the solenoids.

The air injection pump is located under the vehicle below the driver's seat. You should be able to hear it running occasionally - it sounds like a small vacuum cleaner when it runs. If the pump runs, this is not likely to be the problem and you will most likely have to replace the solenoid.

The solenoid is located on the right side of the cylinder head. (see diagram)

DTC P0411 : Secondary Air Injection (AIR) System Incorrect Air Flow Detected

DTC P2440 : Secondary Air Injection (AIR) Valve Stuck Open

DTC P2431 : Secondary Air Injection (AIR) System Pressure Sensor Performance
Circuit/System Description
The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. An electric air pump, the secondary AIR injection pump, provides filtered air on demand to the AIR control solenoid valve/pressure sensor assembly. The AIR control solenoid valve/pressure sensor assembly controls the flow of air from the AIR pump to the exhaust manifold. The AIR solenoid valve relay supplies the current needed to operate the AIR solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The powertrain control module (PCM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.
The AIR diagnostic uses 3 phases to test the AIR system:
DTCs P0411 and P2430 run during Phase 1
DTCs P2430 and P2440 run during Phase 2
DTC P2444 runs during Phase 3
During phase 1, both the AIR pump and the solenoid valve are activated. Normal secondary air function occurs. Expected system pressure is 8-10 kPa above BARO.
During phase 2, only the AIR pump is activated. The solenoid valve is closed. Pressure sensor performance and solenoid valve deactivation are tested. Expected system pressure is 15-20 kPa above BARO.
During phase 3, neither the AIR pump nor the solenoid valve is activated. AIR pump deactivation is tested. Expected system pressure equals BARO.
In all 3 phases, testing is accomplished by comparing the measured pressure against the expected pressure. The PCM can detect faults in the AIR pump, AIR solenoid valve/pressure sensor assembly, and the exhaust check valve. The pressure sensor can also detect leaks and restrictions in the secondary AIR system plumbing.

I have the following codes po410 and po491.......can u please tell me what they are so I can get my car fixed asap


P0410 - SECONDARY AIR INJECTION (AIR) SYSTEM
P0491 - SECONDARY AIR INJECTION (AIR) SYSTEM INSUFFICIENT FLOW (BANK 1)

Secondary air injection (trademarked as Air Injection Reactor) is a process where fresh air is injected into the exhaust system to allow for a fuller combustion of exhaust gasses.

The possible causes are:
SAIR pump low or now air flow
SAIR bypass solenoid leaking/blocked or stuck open/closed
SAIR diverter valve leaking/blocked or stuck open/closed
SAIR air hose restriction
SAIR vacuum hose restriction or leaking

Check to make sure your air filter isn't dirty - and replace if needed. Otherwise I would suggest having your local trusted auto repair facility diagnose and repair the issue. A scan tool will be needed to properly diagnose the issue.

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.

Code P1420 suggests replacing the secondary injection pump relay, where is the relay?


17828/P1420/005152 - Secondary Air Injection Solenoid Valve (N112): Electr. Malfunction Possible Causes
  • Secondary Air Injection Solenoid Valve (N112) faulty
  • Secondary Air Pump Relay (J299) faulty
Possible Solutions
  • Check Secondary Air Injection Solenoid Valve (N112)
  • Check Secondary Air Pump Relay (J299)
The secondary air injection pump relay (J299) is inside the engine compartment, left side, behind air cleaner housing, under a black plastic protective cover you can lift up to reveal it. It's near the brake fluid reservoir beside the odd black plastic cover for the wiring harness beside the shock absorber tower.

Rating my suggestion let's me know how helpful it was correcting your problem. Your rating is truly appreciated and would take the very least of time and effort away from you. Thank you

Obd code of p0411 on a 1999 ford mustang 3.8 v-6 what do I check to correct


That's s failure of the secondary air pump. It'll have to be changed. It's an emissions component meant to help with cold start emissions. It won't cause engine running trouble but at inspection time you'll fail for smog. Change it before then and you'll be fine.
