The check engine light can trigger for a host of reasons, one of which is routine maintenance like oil (5k miles these days). To know what’s causing it, you need to check the codes.
On most cars, if it blinks when starting up then goes away, it’s time to change the oil. If it stays on, it’s past time and/or there’s another sensor tripping.
Don’t ignore the check engine light. It takes like 30 sec to diagnose at any auto parts store, so just drop by and ask for a free scan if you don’t have a reader or don’t want to take it to a mechanic.
Global foundries has a fab nearby, and all they produce are those chips for the old obsolete cars put out by Ford
Not everything has to be latest gen CPUs, there will always be a market for 555 timers and ESP32s
Plus, these have to be automotive grade, which requires a higher tier of durability. Not a lot of profit margin to be made on those sorts of devices.
Except these are the empty headed sensors that trigger the check engine light despite the engine running just fine

Exactly. Modern cars are great at compensating for poor maintenance, but that doesn’t solve the problem.
Maintain your cars properly and they won’t need to compensate like this, meaning you’ll get better fuel economy and largely avoid costly repairs.

Isn’t the check engine light simply a timer and not an actual sensor? Programmed to light at least once a year and at least every 5k miles
