Secondary air pump defective

When the air pump is switched on, this is audible. It sounds a bit like a vacuum cleaner in the engine compartment. A broken secondary air pump has no direct effect on the operation of the engine. However, it is important that it works properly. The catalytic converter filters harmful substances and particulate matter from the exhaust gases. If the air pump is not working properly, there will be more harmful substances than permitted in the exhaust gases during a cold start. If the pump is defective, the lambda sensor measures this and sends a signal to the ECU. The engine warning light on the dashboard will then light up. With an OBD scanner you can read out what the exact problem is. You can order a new secondary air pump cheaply at Winparts. With your car information, you can find a suitable pump for your car.

Secondary air pump

The secondary air pump helps to purify the exhaust gases when the engine is still cold. When starting from cold, the catalytic converter cannot do its job properly. The secondary air pump helps to warm up the catalytic converter faster.
