US fab construction costs twice as much, takes twice as long as Taiwan
U.S. and Europe need to adopt new construction techniques to be competitive.
One of my older cars (2006) did trip the check engine light for oil changes IIRC. I could be mistaken though.
Regardless, checking the codes is always a good idea, never assume.
Don’t listen to the parts store guys, they are there to sell you parts.
Absolutely. But pulling the code is absolutely the first step to figuring out what went wrong. Sometimes it directly indicates the issue, and sometimes it trips due to another issue. I take the code, do a little research, and if I'm not confident in my own diagnosis (or it'll be a costly repair), I'll take it to a mechanic.
But don't just sit on the check engine light. Figure out what it is and address it. In my state, you can't pass emissions testing w/o having a clear check engine light (and yes, they check if you cleared it) or apply for an exemption, so we at least need to take care of it by then.
100% on all points. I used to be a mechanic, and I DIY 99% of my vehicle's needs (except windshields, tires, and full alignments - simply for lack of equipment). Very important to get the codes, because, for example, a P0456 could be caused by something as simple as a loose gas cap (95% of the time), or something could be wrong with the evap system.
Though I'm curious what car you had that tripped the check engine light like that... 🤔
Again, I could be mistaken, but I thought it was my Toyota minivan. My other Toyota (2007 Prius) definitely has a "maintenance" light, and the minivan also occasionally threw check engine lights due to the fuel sensor (often tripped with low fuel in the tank), so I could honestly just be misremembering.
Was it a Sienna, by chance? I have a 2008 Sienna with an ominous-looking maintenance reminder light.
Yup, Sienna.
Nice. Appears mine is currently illuminated 😅
