Question about 2008 Chevrolet Impala

Open Question

I have a 2008 Impala with a 3.5L v6 engine. I have a p2432 code for the secondary injection system. I have taken it to the dealer 2 times. 1 time I think they just cleared the code and the 2nd time they replaced the air pump. The code keeps comming back. Any answers? I would appreciate any help with this concern. The check engine light seems to come on more often when I am decelerating. It ususlly goes back off after a few days.

SOURCE: 2008 bettle secondary air injection sys incorrect flow

the air pump should start when car is cold, if you do not hear a small airplane under your hood, than it is not functioning, if you do, you'll need to do other diagnosis (checking vaccum lines most likely), but being such a new car, a dealer would probably be under warranty.

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 !

2002 VW Passat GLS 1.8T throwing two codes: P0171 and P0411. No noticeable loss in performance. Can I fix this myself?


System Too Lean (Bank 1)

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.

P0411 Secondary Air Injection System Incorrect Flow Detected, check the...Combination valve
...Secondary Air Injection pump motor
...Secondary Air Injection solenoid valve
I would take it to a mechanic

HAVE A 2005 CHEVY TRAILBLAZER WITH P2432 CODE ?


Yhea it's under the truck on drivers side bolted to the transmisson crossmember. There are three 13mm headed bolts holding it on, they go up through the crossmember and bolt to the bottom of the bracket that is holding the air pump on. there are two hoses going to the pump that you need to take off and two electrical connectors. Then you will need to switch a few things over after you get the old one out. Not hard at all, Becarful when pulling the hoses off most of the time the reason they fail is because water has gotten in there, when you take the hoses off you get soaked(i speak from lots of unexpected showers).
