The more I read into emissions requirements, the less I’m convinced there’s a meaningful difference between a 2010 and 2020 engine’s emissions system.
I retract my original statement that a 2010 Polo wouldn’t have the same emissions equipment as a newer car. I suspect a newer engine would still have tighter requirements for sensor values though based on the constantly evolving emissions laws.
California has made their emissions requirements stricter and stricter every few years, but it seems like most of the big changes were pre-2000 that I could find (or future like the upcoming phasing out of ICEs).
Just as a summary of the emissions systems I was considering along with catalytic converters, which it turns out have all been around a long time:
What you’re saying is my understanding too. All those things are 80s tech that back then operated in separate isolated closed loop servo feedback when working right and pissed everyone off when something went wrong because they couldn’t just go out and fuck around with the carburetor until it worked right.
Part of what made obd2 so great for so long was that it gave you the actual measurement to pair with a symptom that would tell you what to test to figure out what part was messed up.
