They could be related. Most likely your air injection is dumping at the wrong time. You really need to get this diagnosed by a professional. Hands on is the only way to do this.

Code p2445 - how to repair or bypass


P2445 code definition

Secondary Air Injection System Pump Stuck Off Bank 1

What the P2445 code means

The secondary air injection system is designed to pump outside air into the exhaust in order to help reduce harmful emissions. This trouble code indicates that the powertrain control module has detected a malfunction with this system on the bank 1 side of the engine.

What are the causes of the P2445 code?

The most common cause of this trouble code is a failed air injection pump. The air injection pump is designed with a check valve inside which only allows air to flow in one direction, preventing exhaust gases from escaping through the air pump and only allowing air to enter. When this check valve fails, moisture is able to get inside the air pump. During the winter months this moisture can freeze, causing the air pump to seize up and possibly break. Other possible causes of this issue would include damaged wiring or connectors associated with the air pump, blown fuses, or a broken serpentine belt

Code po491 on my 07 fusion


Code 491 is for insufficient secondary air injection flow bank one.
There is a device that pumps fresh air into the exhaust system to lower emissions. The sensor that measures air flow is telling the computer the air flow is below standard.
The system would need to be tested.

I have the following codes po410 and po491.......can u please tell me what they are so I can get my car fixed asap


P0410 - SECONDARY AIR INJECTION (AIR) SYSTEM
P0491 - SECONDARY AIR INJECTION (AIR) SYSTEM INSUFFICIENT FLOW (BANK 1)

Secondary air injection (trademarked as Air Injection Reactor) is a process where fresh air is injected into the exhaust system to allow for a fuller combustion of exhaust gasses.

The possible causes are:
SAIR pump low or now air flow
SAIR bypass solenoid leaking/blocked or stuck open/closed
SAIR diverter valve leaking/blocked or stuck open/closed
SAIR air hose restriction
SAIR vacuum hose restriction or leaking

Check to make sure your air filter isn't dirty - and replace if needed. Otherwise I would suggest having your local trusted auto repair facility diagnose and repair the issue. A scan tool will be needed to properly diagnose the issue.

How many air pumps does a 2005 dodge stratus have?


the secondary air pump is one part, it is actually called the "secondary air injection system", so the dealer misinformed u, it is a major component of the emission control system, it is under the hood and injects air into the exhaust system to help clean the exhaust

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
