P0411 FORD code

Trouble code P0411 is a generic OBD-II DTC (digital trouble code) which indicates a problem with your vehicle’s secondary air injection system. The secondary air injection system pumps air into the engine’s exhaust stream when the engine is cold and while decelerating.Trouble code P0411 is a generic OBD-II DTC (digital trouble code) which indicates a problem with your vehicle’s secondary air injectionsecondary air injectionPumped air injection systems use a vane pump called the air pump, AIR pump, or colloquially “smog pump” turned by the engine via a belt or electric motor. The pump’s air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system.

How do you fix a P0411 code?

What repairs can fix the P0411 code?

  1. Air pump replacement.
  2. Removing carbon buildup from secondary air system.
  3. Vacuum hose replacement.
  4. Air solenoid replacement.
  5. Repairing or replacing wiring harness issues.

How much does it cost to replace a secondary air injection pump?

How much does it cost to repair a secondary air injection system? You can expect to pay about $450 to replace your secondary air injection system. These costs are split between the cost of materials and the cost of labor. You can save money by replacing your system on your own.

What does secondary air injection incorrect upstream flow detected mean?

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.

Where is the secondary air injection system located?

The secondary air injection pump is usually located on the engine or at least in the engine bay. It can sometimes be hidden deep into the engine bay, but mostly you will find it installed pretty visible on the engine.

What could cause a P0411 code?

DTC P0411 indicates the engine control unit (ECU) has detected an air flow problem within the secondary air injection system. The trouble code is fairly vague, in that, it does not identify a particular defective air injection component and requires a hands-on diagnosis to determine the root P0411 fault.

What is the secondary air injection system?

Secondary air injection (commonly known as air injection) is a vehicle emissions control strategy introduced in 1966, wherein fresh air is injected into the exhaust stream to allow for a fuller secondary combustion of exhaust gases.

Can you drive without secondary air pump?

Technically speaking, you can drive without a secondary injection pump. However, doing so is not advised. This stems from the fact that a faulty secondary injection pump can cause a host of drivability-related issues, most of which can vary significantly in severity, on a case-by-case basis.

How much is an air pump at gas station?

Some gas stations charge as much as $1.50 for air. And many drivers, not knowing any better, will drop quarters into the slot so they can fill their tires.

How much is an air pump for a car?

A standard air compressor for cars will run between $30 and $50. The price is determined by materials, the motor’s power, whether it’s digital or analog, and its hose. The most important thing is that it’s powerful enough to fill your tires since it won’t be of use without that ability.

What is an air injection diverter valve?

Air Injection Diverter Valve. So, the air pump diverter valve, allows air supplied from the air pump, to be pumped; into the exhaust stream. Thus, reducing hydrocarbon and carbon monoxide tailpipe emissions. Consequently, it functions, as a one-way valve; allowing the air to pump through the exhaust.

What is code P0410?

Code P0410 is the result of the Engine Control Module (ECM) indicating a malfunctioning Secondary Air Injection System. This happens when the O2 sensor does not accurately detect the changes in the O2 level of the exhaust while the air injection system is functioning.
