A Look Into Secondary Air Injection System Repair.

As a matter of fact, different vehicles makes and models uses different codes to indicate different secondary air injection system faults. This is an integral part of the emission control system responsible for pumping air into the engine exhaust system when it is cool in order to help warm catalytic converter. Mostly these systems develop faults when the vehicle is exposed to a cold climate or weather.
It is made of an air injection pump that is responsible for secondary air injection through a one-way check hose in order to provide maximum protection. Click secondary air injection to read more about secondary air injection system repair. There are various factors that cause the system failure and faults. The first cause is air blockage. If the system inflow air is blocked, little air will be supplied to the exhaust causing faults. Another factor is when ozone sensors get slow to respond.
This increases the level and volume of O2 in the vehicle exhaust system making it unable to breathe properly. This system can also suffer faults when the catalyst becomes clogged either fully or partially. This increases back pressure in the vehicle exhaust forcing the vehicle to stop. Another factor that may cause this problem is when the injection pumps fail to make contact but instead relay the contact.
Other causes of Toyota tundra secondary air injection system include connector damage, getting loose or damaged. Wiring faults or damages on the air injection pump defects. There are some symptoms that indicate the vehicle is suffering from secondary air injection system failure. The vehicle can start making unusual noise emanating from bearings.
The engine light can be illuminated and the vehicle indicates there is a problem. Visit toyota tundra secondary air injection system to learn more about secondary air injection system repair. Engine running too rich is another symptom indicating there is excessive ozone is the exhaust. This problem is diagnosed through scans on documents and codes on the freeze frame on the data provided in order to understand what the problem is.
You can also diagnose through codes retesting so as to verify system functionality. Repair any ozone sensor before diagnosing. Check injection relay if it is facing power cut in case the pump fails to turn on. Pump resistance checks and replacement of sluggish ozone sensor. Secondary air injection system repair is done by either replacing the power relay and air injection pump.
You can also repair these faults by replacing all the ozone sensors that are slow due to age. You can also repair the system by replacing the pump intake filters that have been clogged or blocked by different material and debris. You can also repair by replacing all the valves that have failed. Repair also involves wiring faults correction, fuses and hoses replacement. Learn more from https://www.youtube.com/watch?v=pRSl_tS3kl0.
