2005 Rio sedan, OBD code P01000001 and P0455

10-05-2014, 07:21 PM
My 05 Rio Sedan keeps posting codes P0101 and P0455. No mechanics have been able to fix either one.
For code P0455 the gas cap has been replaced several times and all hoses have been checked for cracks/leaks. Nothing found.
For Code P0101 the air filter was replaced, the MAF was cleaned and later replaced.
The car only has 77000 miles on it.
Code P0455 started showing soon after I bought the car with 50000 miles on it.
Code P0101 is a recent code, showing several times in the past 6 months.
Any suggestions?
