This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

SOURCE: po410 code on a chevy trailblazer

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: Secondary Air Injection System Malfunction

P0410 secondary air injection system malfunction. I've dealt with this problem myself. It's either the air pump which is located under the driver's side door on the frame, or it's the valve on the engine that is sticking.
The air pumps are notorious for "freezing up" in cold climates due to water sitting in the pump and freezing and then breaking the impeller from the shaft in the pump. This is what happened with mine.
Remove your pump and test it. If it spins and blows air,then it's fine. Then check your valve on the engine. If that opens (which they like to get corroded with exhaust gasses and stick) Then that will be ok. If not, you'll have a pretty good idea what is going on.
I wnt ahead and replaced both the pump and valve, which were both crappy.
GM also has a check valve that you can install to prevent water from entering the pump. I just drilled a small hole in the bottom of mine to "drain" the water.

Yes. That is exactly it. The Air Intake Temp Sensor is built into the Mass Air Flow Sensor on the Air Filter Box. Below is a picture...

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 !

My 2005 chevy trail blazer has code p0410 and i dont know what needs to be replaced provide that i know that it means secondary air injection system but i need to know the part that needs replacement


check the air pump on your trailblazer, make sure its clean inside and the hoses are properly fastened. also check to make sure it works properly by listening for it when you start the vehicle. if the air pump is working correctly, replace the position 1 o2 sensor meaning the sensor on the exhaust manifold. the air pump is located under the vehicle, inside the frame rail on the drivers side in front of the transfer case crossmember with 2 hoses connected to it.
