Good day all,

I have an 8th gen Si that has surpassed 400,000 Kilometers. I'm familiar with older generation sensors and cleaning practices but not sure which of those apply to the newer 8th generation sensors and parts.

I was wondering what sensors should be removed, cleaned and reinstalled periodically?

On older civics we'd do the throttle body, map sensor, IACV, FITV (if applicable) and O2 sensors typically. Do any of you do anything like this on the 8th gen sensors or parts?

 

No one does maintenance on their 8th gens beyond oil changes?

A tech buddy of mine mentioned changing the timing chain tensioner every 100,000 KM.

Guess the sensors are lifetime until ECU tells you a code to replace them.........
