This question is regarding a 1999 Chevrolet s10 Blazer, 4.3L V6.
My trouble started a few months ago with a check engine light. I scanned the computer and found a P0410 code (Secondary Air Intake Failure). I researched and found that the smog pump was probably bad. I replaced the smog pump, cleared the code. The code came back, same thing.
I checked an inline fuse that comes from the smog pump, it is supposed to blow when the smog pump fails. It was intact.
I researched again and found that there are one way vavles after the smog pump that are there so the air only flows one way into the exhaust. I replaced those, the code stayed away a little longer but still came back.
I don't know what else to do. The O2 sensors appear to be ok. Maybe they aren't. Has anyone ever seen this? Does anyone have a solution or an idea?
Please help. I am way over my smog date right now.
have the same problem?
