Where are the relays on an air injection pump?
There are 2 relays. The one they gave you is on the pump. The other is in the fuse block. You need a scan tool to check all this. You need to command the system on to verify the pump and solenoid are working. The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start.
How does the secondary air injection pump work?
The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. The secondary AIR injection pump provides filtered air on demand to the AIR solenoid check valve assembly.
Why do I have a code p0410 on my secondary air pump?
If you have a code P0410 that relates to secondary air pump, there are a few possibilities that could trigger this code. 1. It could be a bad secondary air pump. We have a video that will show you how to test a secondary air pump 2. It could be relay that does not activate the secondary air pump 3. It could be bad fuse 4. Bad connection
How does the air pump control module work?
In all 3 phases, testing is accomplished by comparing the measured pressure against the expected pressure. The control module can detect faults in the AIR pump, AIR solenoid, pressure sensor, and the exhaust check valve. The pressure sensor can also detect leaks and restrictions in the secondary AIR system plumbing.

When to replace a secondary air injection pump?
If you’ve already experienced engine stalling, poor acceleration, and a check engine warning light, then you need to have the secondary air injection pump checked out immediately. If it is proven to be the problem, have it replaced by a certified mechanic.
What do you need to know about a secondary air pump?
If you’re wondering what a secondary air injection pump is, you’re not alone. In this article, we’ll go over the purpose of the secondary are pump as well as the symptoms you should watch for that indicate the pump is failing. What Does a Secondary Air Pump Do? What Does a Secondary Air Pump Do?

When is the fuel pump relay turned on?
The fuel pump relay is an important component of the fuel system of your vehicle. The fuel pump relay gives the fuel pump power when it is time to build up fuel pressure in the rail. Whenever you turn on the ignition of your vehicle, the fuel pump relay is turned on. There are different reasons due to which the fuel pump relay fails.
In all 3 phases, testing is accomplished by comparing the measured pressure against the expected pressure. The control module can detect faults in the AIR pump, AIR solenoid, pressure sensor, and the exhaust check valve. The pressure sensor can also detect leaks and restrictions in the secondary AIR system plumbing.
What kind of system is an air pump?
An air pump, also commonly referred to as a smog pump, is an emissions component that is part of the secondary air injection system.
How does the secondary air pump reduce emissions?
The secondary air injection pump is an emissions component that lowers emissions by pumping in fresh air just before the catalytic converter.
The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. The secondary AIR injection pump provides filtered air on demand to the AIR solenoid check valve assembly.
What should the fuse look like on Mercedes Benz air suspension?
Procedures are similar for other Mercedes-Benz with air suspension, but the location of the relay and fuse may change. In this S-Class W220, the air compressor motor /pump is protected by Fuse 32, which is a MaxiFuse 40 Amp. Here is what a good fuse should look like.
What causes a Mercedes Benz air suspension to fail?
Faulty relay or Blown Fuse The air suspension compressor relay is known to fail. It could either not engage the air suspension compressor at all or even worse keep it engaged for longer that required. If the air suspension compressor is kept engaged for too long, it can get damaged.
Where is the fuse for the air suspension compressor?
Also, check the fuse for the air suspension compressor. On the Mercedes-Benz S-Class, the fuse box that contains the air suspension compressor relay and fuse are located on the right (passenger side) of the engine. Look at the 40 AMP fuse F32, make sure that it is not blown.
Where are the fuses located in a Ford E-350?
The fuse panel is located below and to the left of the steering wheel by the brake pedal. The power distribution box is located in the engine compartment. The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems from overloads.
Where is the relay module located in a Ford E150?
The engine compartment relay module is located in one of two places depending on which type of engine your vehicle is equipped with: Gasoline engine: driver side of the engine compartment above the brake master cylinder. Diesel engine: passenger side of the engine compartment behind the power distribution box.
Procedures are similar for other Mercedes-Benz with air suspension, but the location of the relay and fuse may change. In this S-Class W220, the air compressor motor /pump is protected by Fuse 32, which is a MaxiFuse 40 Amp. Here is what a good fuse should look like.
When to replace fuses on Mercedes Benz E class?
Location of fuses and relays on Mercedes Benz E Class All Models, years 2003 to 2008. If you replace any fuses, make sure to replace it with the same color fuse. If there is an underlying problem you could overload the wires or even cause more serious problems to that circuit if you use a higher ampere fuse.
Where is the air pump on my car?
The air pump is located On left front frame rail, forward of fenderwell. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
