How important is a smog pump?

The secondary air injection pump (also referred to as a smog pump or SAI pump) is responsible for lowering the number of carbon emissions that come out of the tailpipe of a vehicle. This is necessary since a vehicle engine is never 100% efficient in the combustion process.

How much does it cost to replace a smog pump?

How much does it cost to replace a smog pump? The average cost for air pump replacement is between $510 and $532. Labor costs are estimated between $77 and $98 while parts are priced between $433 and $434. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.

What are the symptoms of a bad air pump?

Reduced horsepower. Another common symptom of a bad air pump is a reduction in power output from the engine. Again, a failed smog pump can upset the tune of the vehicle, which will negatively impact overall engine performance.

A failed emissions test in conjunction with weak acceleration is a decent indicator that it is the pump’s fault. You may be driving normally and then suddenly experience engine stalling or hesitation in your vehicle. A secondary air injection pump that is wearing down can cause inconsistent power gaps from the engine.

What happens when a secondary air injection pump wears down?

A secondary air injection pump that is wearing down can cause inconsistent power gaps from the engine. One minute the power may be fine, and the next it may be weak. If the pump is not replaced, the power will stay weak.
