- Air pump replacement.
- Removing carbon buildup from secondary air system.
- Vacuum hose replacement.

Can a bad O2 sensor cause a P0411 code?
What Does Code P0411 Mean? Diagnostic Fault Code P0411 is indicative of a general lack of flow from a vehicle’s secondary air injection circuit. In turn, this lack of airflow is registered by the affected vehicle’s O2 sensors and is recorded by the PCM/ECM as a diagnostic fault.
What causes code P0411?
Diagnostic trouble code (DTC) P0411 stands for “Secondary Air Injection Incorrect Flow Detected.” This code warns about a potential airflow issue in the secondary air system.
What does Bank 1 secondary air injection mean?
Note though that both definitions have the same basic meaning, which is that the Secondary Air Injection system is either not injecting sufficient air into the exhaust system, or that it is not injecting any secondary air at all. “Bank 1” refers to the bank of cylinders that includes cylinder #1 on engines with two cylinder heads.
What is the purpose of the secondary air injection system?
The purpose of the secondary air injection system air flow/pressure sensor circuit bank 1 is to reduce the amount of hydrocarbon exhaust emissions during engine start-up when the weather conditions are cold.
What are the components of the secondary air injection pump circuit?
Based on the specific vehicle, this circuit may incorporate several components including the secondary air injection pump, check valve, pressure sensor, air control valve and the PCM. Perform a thorough visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots.
How does the ECM monitor the pressure in the secondary air passage?
The Engine Control Module (ECM) monitors the pressure in the secondary air passage using the pressure sensor located on the air switching valve in the secondary air injection system.
