    I recently replaced my two secondary air injection pumps on my truck. I have tested the pumps with a separate 12V Battery and they go off the minute I hook them to the battery. However, when connected to the actual truck they dont seem to be drawing any power.

    I saw that (and correct me if wrong) this 2010 model doesnt have a designated relay for the secondary air injection system?

    If the pumps are not being triggered to go off when they should (aka no signs of current going into them) what could be causing this issue?

    I know they are supposed to shut down after a few seconds once engine is warm but they dont seem to be on at any time.

    Edit: This morning my secondary air injection pumps were working fine. I think it was so hot out yesterday they werent getting triggered.
    I still have a P2432 code (secondary air injection system air flow/pressure sensor circuit low bank 1) and C1201 (engine control system malfunction)
