Go on, I'll listen, I do most of my own automobile repairs myself and to get good quality factory sensors costs an arm and a leg! Aftermarket sensors are hit and miss at best, sometimes they don't work at all. You need the ability, or tools, just to test them t see if they are of any good.

I have semis. They now have over 13,000 sensors.

I just spent $765 on a nox sensor just to get the check engine light to turn off on a 2018 Kenworth so that the check engine light was available to check the other sensors that could shut the engine down like a derate.
