Secondary air injection pump failure can be easily detected if you are aware of the symptoms to watch out for.

Below you’ll find some of the most common signs of secondary air injection pump failure.

ILLUMINATED CHECK ENGINE LIGHT

The first signs of a malfunctioning secondary air injection pump is an illuminated Check Engine light.

The warning light is on because the engine control unit can automatically detect when the secondary air injection pump starts to malfunction.

FAILED EMISSION TEST

The purpose of the secondary air injection pump is to reduce hydrocarbons in your emissions system.

A malfunctioning secondary air injection pump, means your emissions system will be allowing too many hydrocarbons.

WEAK ACCELERATION

A bad secondary air injection pump in your car will also cause problems for the air-to-fuel ratio in your internal combustion engine.

If this ratio is too lean, then your engine will not generate enough speed whenever you step on the gas pedal.

ENGINE STALLING

A secondary air injection pump that is wearing down can cause inconsistent power gaps from the car engine.

If the pump is not replaced, the engine may continue to stall and will demand expensive repair work.

LOW IDLE

The normal RPM of an idle engine is somewhere between 600 to 1,000 RPM.

When the RPM drops, you will experience more vibrations and stalling while driving.

REMEMBER

Always take your car to a certified technician for receiving adequate repair.
