Hi ,thanks for adding me,I need help ,2011 Camry 4 cyl ,shows p101 code which is air sensor ,I replaced it ,plugs ,cleaned throttle Body ,car has 140,000 miles ,it started rough idle is why I replaced this stuff ,put it in park and it idles up and down,rough idle ,dealership says air sensor ,PCV valve ,or air intake system .it also shows a emblem on instrument cluster which is a slippery road looking thing ,I really need help here ,thanks

If check light is on, the other dash light will be on.

Did the check light come on at the same time the idle issue started?

Did you replace the air temp sensor? If so is the check light now off?

Check the engine air intake tube for cracks, leaks, etc.

Check PCV valve for function and hose for cracks and plugging.
