Secondary air injection, which is commonly known as air injection in the car world, is a vehicle emissions control strategy that is used in most modern vehicles. This allows fresh air to be directly injected into the exhaust stream, leading to a better ratio of secondary combustion exhaust gases. Since this system is so crucial to the inner workings of your car, it is not necessarily very cheap to repair. The total secondary air injection system replacement cost as an average price comes in around $618 for the car owner.
The secondary air injection system usually consists of an electric pump, a control relay, a pneumatic control valve, and a combination valve. This system is controlled by the engine control unit, which is the vehicle's computer. While the system is working, the electric pump is switched on the engine control unit for the control relay.
The vacuum used in the secondary air injection system causes the combination valve to open and the extra air that has been transferred by the pump to be given into the exhaust pipe behind the exhaust valves. As soon as this control becomes active, the secondary air system becomes deactivated. When the engine control unit turns off the electric pump and the pneumatic control valve, this prevents extra emissions from damaging the electric pump.
How to replace a secondary air injection pump
As we know, the air injection system is in charge of introducing oxygen into the exhaust engine at specific times that are supposed to reduce emissions. The main components involved in the emissions system and the air injection system is the powertrain control module, air injection relay, air injection hoses, the air injection valves, and the pump. The powertrain control module is the automotive components and control unit that is used in your car to play a huge part in the inner system of your car, working together with the engine control unit and the transmission control unit.
The air injection pump is either one of two types – belt driven or electric. In this case for the replacement of the secondary air injection repair and replacement, we will give you the steps of the belt driven design for the air injection system. This will determine the overall secondary air injection system repair cost.
The air injection pump is the main focal point of the secondary air injection system. Air is entering the pump and then transferred by ways of the desired location via the powertrain control module controlled valves. During the time when the engine is warming and revving, the air is then transported to the exhaust manifold. Then, in most modern cars, the air is then directed to the catalytic converter once the engine reaches the operating temperature.
The first step in the secondary air injection system and pump repair is to remove the air in the injection pump. You have to do this by a few key steps. First, locate the secondary air injection pump. The air pump will be placed at the front of hte engine with the serpentine belt wrapped around it. Make sure there is a diagram that shows the positioning of the belt that is under the hood, so you know how to reinstall the pump when you are done.
Next, remove the serpentine belt. Do this by inserting a ratchet end into the square tensioner and push the tensioner away from the belt, sliding the belt off of the pulleys. The car’s serpentine belt is in charge of various systems in your car functioning correctly, like the power steering, water pump, alternator, and air conditioning. Keeping your serpentine belt in a good condition can maintain these automotive components in good condition and lower the overall secondary air injection pump repair cost.
If you do not keep your serpentine belt working correctly, you will have to pay between $25 and $75 on the parts only, but this can get much higher depending on the location of the service. The serpentine belt is responsible for nearly every system in your vehicle, like air conditioning, steering pump, and the water pump.
If you feel like your serpentine belt might be getting worn out over time and could potentially higher the overall secondary air injection system replacement cost, then you might notice some of these signs and symptoms. You could begin hearing strange engine sounds, poor air conditioning due to the insufficient power, no power steering, and the battery warning light illuminating in your vehicle.
Once the belt is removed, remove the hose. Undo any clamps and slide the hose off the connection. Remove the vacuum line and electrical connections as well, along with the air pump mounting bolts and the air pump from the vehicle. Doing these steps on your own can lower the overall secondary air injection pump repair cost for you.
After these steps are completed. It is time to finally install the new secondary air injection pump. The first thing to do is to install the new smog pump and tighten the mounting bolts until they are snug and secure. Put back the electrical connections, the vacuum lines, the air pump hoses, and the serpentine belt.
What does this P0401 code mean when you see it appear on your diagnostic tool or you bring your vehicle to the local mechanic? The Code P0410 indicates that you have a problem with the secondary injection system and is whether caused by a direct mechanical or electrical fault. This can enhance the total price of the secondary air injection pump repair cost.
Trouble code P0410 is usually brought about by the vehicle’s emission system if the system is not working correctly or if the air pump is damaged. Symptoms of abad ro failing air pump include all of these factors, which can make the overall secondary air injection pump repair cost higher than you anticipated.
First, the engine could be running rough. One of the first symptoms and easily noticeable signs of a failing air pump is a rough running engine, since the engine will have trouble idling, may drop in speed, have trouble accelerating, or stall when you press down the pedal to go faster.
Second, you may experience reduced horsepower in your vehicle. This is another common symptom of a failing air pump, since this can cause the engine to stall, hesitate, stumble on acceleration, or cause a huge reduction in the overall power output of the vehicle. This can make the price of the secondary air injection pump repair cost higher.
Next, your check engine light may come on your dashboard, showing that here is a problem that needs to be fixed as soon as possible. This will usually occur only after the car’s computer has detected that the air pump has completely failed or damaged beyond repair, or there is an electrical issue with the circuit that has occurred. A check engine light can also be turned on by other problems, so you will want to figure out if any of these causes can affect the secondary air injection pump repair cost.
Since the damaged air pump can turn on the P0410 code, this directly affects the secondary air injection system. The main task of the air pump is to give air into the exhaust system in order to reduce the overall emissions level and reduce the pollution from your vehicle. The air pump is in charge of bringing in air from the outside and pumping it through the one-way check valve to the banks that are located within the exhaust system.
Symptoms and Causes of the P0410 Trouble Code
We know the trouble code directly affects the air injection system repair cost. Ist is crucial to notice and recognize the common symptoms that you will experience when this code appears and the causes of why this P0410 code is generated. One of the symptoms of the trouble code is the check engine light turns on, the engine hesitates while accelerating, the noises are coming from the air pump, the engine is running too rich, and the fuel economy is reduced.
Causes of this P0410 trouble code that affect the secondary air injection system repair cost are damaged air pump check valves, bad pump relays, defective control solenoids, blockages in the air injection system, a bad or damaged O2 sensor, clogged catalyst, a blown air pump fuel, and damaged vacuum lines.
