P0101 Code

Received a P0101 code CEL on just after DIC message was cleared that said " Attention Required" Cleaning Exhaust Filter, continue driving. SO I did for about 30 min, was late to work ect. got in truck to drive home, 20 later CEL came on w/P0101 code. Is - could this be related ??? Have 80k on truck & replaced air filter w/stock fram about a month ago have driven 2k since then.

Was the previous air filter an oiled filter?


P0101 is mass air flow sensor issue
