Review on GM Genuine Parts Secondary Air Injection Shut-Off Valve 12660127 for Improved SEO by Josh Garber

It didn't fix my p0411 I'm at a loss. Fuses are ok, wiring is ok, test lamp is on, air pump is ok, leads are carbon free. I don't understand why my cel light stays on. That was my last resort. The part works fine, I won't give a bad review because it didn't solve my problem, it's not a part error update. The dealer replaced the old one with a Dorman air pump. They didn't tell me that before I bought them, so I already knew what the problem was. Dorman is electronic junk and bam fixed my problems. The aftermarket electronics in GM vehicles don't match well, they don't provide the necessary voltage for the computer to read, everything is good, especially the O2 sensors, so if you have a GM get GM parts, it costs money . So, I got a new air pump and valve.
