SEL code P1418, replaced secondary air pump
My SEL is giving code P1418. My secondary air pump only runs for 5 seconds on a cold start. I thought the pump was bad so I replaced it, but the same result... only runs for 5 seconds on cold start. When I disconnect the secondary MAF sensor, the pump runs for 23 seconds. Does this sound like a bad sensor or something else?

Crack in the check valve vacuum line. I spliced it and the SEL has turned off.
