How much air does a smog pump move?

Think of the smog pump as a fan, not a compressor. It ingests air at 1 atm and pumps air out at 1 atm. As mentioned above, it just pumps fresh air into the exhaust to aid in the catylitic converters chemistry.

Smog pumps can be used as “superchargers”. They can produce up to 50 psi. They do unfortunately only move 50-ish CFM which makes them useless to anyone that runs more than 6-700 cc’s in their engine.

how does a smog pump work? The smog pump is responsible for supplying fresh, pressurized oxygen into the exhaust stream near the exhaust manifold. This fresh air then travels through the diverter valve, check valve, and to the exhaust manifold where it’s mixed with exhaust gases to help burn off any unused hydrocarbons.

can you drive with a bad air pump?

You may be driving normally and then suddenly experience engine stalling or hesitation in your vehicle. A secondary air injection pump that is wearing down can cause inconsistent power gaps from the engine. One minute the power may be fine, and the next the RPM drop too much and the engine shuts off.

What is a smog pump on a car?

An air pump, also commonly referred to as a smog pump, is an emissions component that is part of the secondary air injection system. It is responsible for pumping clean air into the vehicle’s exhaust stream to promote a cleaner and more complete burn before the fumes exit the tailpipe.

How long does the secondary air pump run?

120 seconds

How much does it cost to fix a secondary air injection?

All cars are required to have secondary air injection systems, which make exhaust emissions cleaner and help to combust more harmful gases. If your secondary air system fails, then replacing it will cost you between $270-$390. The labor should run you about $90, while parts cost, on average, about $250.

How much does it cost to replace an air injection pump?

The average cost for an air pump replacement is between $560 and $696. Labor costs are estimated between $88 and $113 while parts are priced between $472 and $583.

How much horsepower does a smog pump use?

The smog pump is a “cheater” in that it pumps fresh air into the exhaust, and only uses 1-2 hp tops.

How do you fix a secondary air injection system malfunction?

To get rid of this error code, you can do the following: Replace both the air pumps and the one-way check valve. Try and clean the air pump and test it. The one-way air check valve must be replaced as well. Replace the inlet hose of the air pump. Replace the fuse of the air pump (you can find it under the hood)

Do you need a secondary air pump?

The air injection smog pump pushes air into the exhaust system right after the exhaust manifold, to help intercept and burn those unburned fuels. The system is critical to help cars achieve government emissions standards. So, the law says you need a secondary air injection system.

Does a bad smog pump affect gas mileage?

The smog pump really shouldn’t affect mileage as all it does is pump air downstream into the exhaust.

What is the purpose of secondary air pump?

The purpose of the secondary air injection pump is to prevent hydrocarbons from getting into the environment. A lot of times the secondary air injection pump is called a smog pump for this reason. The smog pump is located right past the exhaust manifold allows air to be pumped into the exhaust.

What does an air pump check valve do?

The air pump check valve is the valve that allows air supplied from the air pump to be pumped into the exhaust stream to reduce hydrocarbon and carbon monoxide tailpipe emissions.

What causes a secondary air injection system malfunction?

A faulty pump is generally the most frequent cause of the system failing. Faulty ground and voltage supply can also cause the pump to fail. Blocked or leaking lines can also cause the failure or malfunction of the control or combination valve, resulting in the failure of the secondary air system.

What does p0410 code mean?

P0410 is an OBD-II generic code that the engine control module (ECM) detected the engine O2 sensor did not detect an increase in the O2 level in the exhaust when the air injection system was commanded on during an active test.

What is Mercedes secondary air pump?

Mercedes – Secondary Air Injection System Issues. This is a critical system in your Mercedes that helps decrease tailpipe emissions while the car is warming up. The system works by using an air pump to inject fresh air into the cylinders to lean out the rich fuel mixture that occurs during engine startup.

Where is the smog pump located?

The air pump is at the front of the engine with the serpentine belt wrapped around it.

How do you check a smog pump?

Spin the pump shaft clockwise while listening for unusual bearing noises. You should hear some noise from the vanes in the pump. The same noise should change pitch/tone when spinning the pump backward. If you hear the rollers in the bearings, either change the bearings or the pump.
