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 !

How to fix P2430 code on a 2006 Pontiac Grand Prix


P2430 Secondary Air Injection System Air Flow/Pressure Sensor 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 2, only the AIR pump is activated. The solenoid valve is closed, this is p2430 and p2440. -The AIR system pressure sensor is stuck. good-day !!
