What is a air diverter valve?
The air diverter valve is designed to enhance the clean burning ability of the modern engine by adding clean air into the emissions system in an effort to push out pollutants. The air diverter valve is essentially a vacuum-operated system that supplies pressurized air from the air pump into the exhaust manifold.
What does an air diverter bypass valve do?
The air diverter valve helps to put clean air into the system to push out pollutants, without letting the exhaust fumes out. This part works in conjunction with the air bypass valve and in most cases they will have to be replaced as a pair.
How does a smog pump diverter valve work?
The smog pump is responsible for supplying fresh, pressurized oxygen into the exhaust stream near the exhaust manifold. The spinning vanes of the air pump forcing air into the diverter valve accomplish this. When needed, the diverter valve will release excess pressure into the air cleaner.
Can a secondary air pump be repaired?
If there is a problem with the air injection system, this can result in high emissions levels, engine performance issues, and a higher secondary air injection system repair cost. In order to fix this, you can replace the secondary air injection pump on your own.
How do I know if my diverter valve is faulty?
Symptoms of a faulty diverter valve
- Taps not getting hot water. The most common symptom of a faulty diverter valve is when you don’t get any hot water to your taps and showerheads.
- Lots of hot water, but no heating.
- You have hot water only if the heating is on.
Is it bad to remove diverter valve sensor?
Unplugging the connector will stop it working and cause the compressor stall. The ECU will also see it and store a fault, with the likelihood of impaired performance.
Can you unstick a diverter valve?
Diverter valves can become damaged or stuck. This is because they’re a moving part and can be oscillating between being open or closed many times a day. However, they are fixable. If you have no hot water, try turning the heating on.
How do you unblock a diverter valve?
After you remove the lid of the boiler, you have to locate the diverter valve mechanism. Run tap water on hot and observe the diverter valve. If you run hot water, the valve is supposed to close in order to divert it to the tap, meaning it should move. If you see no movement, then it’s stuck.
When do you need to replace an air diverter valve?
The air diverter valve is not inspected during any maintenance or service unless there’s a problem. Over time and through normal use, the valve can wear and eventually fail. Many pump assemblies include the air diverter valve and must be replaced together.
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.
Where is the air diverter valve located on a car?
For purposes of this HOW TO article, we’ll assume that you’re replacing a singularly air diverter valve; which is common with Ford and GM four cylinder engines and some six cylinder engines. This component is typically located on the passenger side of the engine compartment and secured to a bracket near the exhaust system.
What kind of material is an air diverter valve made of?
Most air diverter valves are metallic, but some are made from hardened plastic. As the above image indicates, there are three air supply lines that are attached to this component. The air diverter valve is typically secured to a bracket with two bolts (which is what the two holes on the left side of the unit are for).
