Secondary Air Injection Pump

[jhshelton]

Durametric showed usual 996 codes secondary air injection pump codes.

 

Dismantled the pump, bearings are good, electrical connection good, but the filter was very dirty. Can the filter inside the pump be replaced or, new pump the only fix?

I do not believe the internal filter is available as a separate part.

If the codes suggest a problem with the secondary air injection SYSTEM, I've been there before. Do not fail to assess and replace the vacuum reservoir at the beginning of the repairs and not at the end when all else fails.

The vacuum reservoir should be pressure tested. Easy project. The leak is usually in the base where it seals to the dome. Not visible to the naked eye. Pressure test only confirms.
