5 Symptoms Of A Bad Secondary Air Injection Pump Symptoms of a bad secondary air injection pump. when the secondary air injection pump fails, you will notice the check engine light. it also leads to a failed emissions test, slow acceleration and overall decreased performance. aside from those symptoms, the idle rpm may also be slower, even to the point of stalling the engine. 1) check engine light. one of the early symptoms of a bad secondary air injection pump is the check engine warning light turning on. the engine control unit can automatically detect when the secondary air injection pump has a problem. since the functionality of the air pump impacts the engine, any problem with it will activate the check engine.
Is Your Secondary Air Injection System Malfunctioning Symptoms And Let us look at the signs of a bad air injection smog pump. 1. check engine light. one of the most common symptoms of a bad secondary air system is that the check engine light will come on. this light comes on when there is a problem with the engine, and it can be triggered by a variety of issues, including a failing secondary air injection pump. This stems from many variables, including the amount of labor time required to complete such a repair, as well as variances in the cost of a particular replacement air pump. however, the average cost to replace the secondary air injection pump often falls within a general range. this range typically spans from $250 $450, with somewhere in the. 1. engine is running rough. one of the first symptoms of a bad or failing smog pump is a rough running engine. when a smog pump fails the finely tuned air fuel ratios can be upset, and it will negatively affect the performance of the engine. the engine may have trouble idling, and may drop in engine speed, or stall when the pedal is pressed. Pump: the pump is the heart of the secondary air injection system. it is responsible for drawing in fresh air and delivering it to the exhaust system at the appropriate pressure. electric motor: the electric motor powers the pump, enabling it to generate the necessary air pressure.

If the check valve fails, hot exhaust gases can sneak back into the system, damaging components, such as the air pump and air management valves. if the module detects a problem due to a faulty check valve, it will turn on the check engine light and store a diagnostic trouble code (dtc) in its memory. to better understand air check valves, it. If your vacuum pump is at the ready, here’s how to use it. to see if the secondary air injection pump has failed, hook it up to the control valve hose fitting and start your vacuum pump. if the pressure is low or fluctuating, there is a leak. testing the combination valve is a similar process. the combination valve (kombi valve for german.
