The secondary air injection comes from an electric air pump (replaces the old eng. driven smog pump), it seldom runs, but when the car is 1st started you should hear if for about one minute, kinda sounds like a muffled hair dryer. The most common issue is the hoses get knocked off, 2nd is the electric motor failing.

SOURCE: No power leaving the relay

Are you testing the relay when the engine is cold?
The air injection pump works for a very short period of time during initial cold engine start.

Once the exhaust stream is warm enough to support O2 sensor function, the pump shuts off and will not come on again until conditions are met.
Let me know.
Regards,

SOURCE: replaced secondary air pump with new unit 3 days

There is a fuse holder box below the battery tray. There is a relay, 30 amp fuse, and a 10 amp fuse in it. The battery and tray have to be removed to access the fuse box.

P0128 is coolant operating temperature operating too low. This can be contributed to the Thermostat stuck open or faulty electronic radiator fan clutch. This is common, I had the same issue and replaced the thermostat and fan clutch and had the clutch re-programmed (required) at the dealer. As for the P0410, check the air pump fuse, if blown it will set this code on. Also check the air pump hoses for water and cracks. Hopefully this helps!!

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.
