Came 2 days after the delivery date given when ordering. Stopped working after 3 weeks, engine light came back on and same code came up as the first time.

Working on a 2011 Silverado with a 6.0l Vortec. Long term fuel trims seemed to be a bit high at +12% with OEM sensor. Trims seemed to stay high even at higher throttle but would level out with MAF unplugged. That tells me a vacuum leak is unlikely. Took a gamble on the WALKER sensor and it performed much worse. Was reading ~6 g/s at hot idle with the OEM MAF and dropped to ~4.5 g/s with the aftermarket. This drove fuel trims to a combined +35% for both banks. I knew the Chinese knockoffs would be a waste but expected more from WALKER. Going to replace this with OEM GM part.
Did at least include a security torx bit and extra screws. Though they are machine thread and pretty sure any housing these sensors would mount to would be plastic.
