Hi all,

I've owned my 2003 HCH, CVT, since the winter of 2005 and have been happy with it ever since. 130k miles on it now and I perform regular oil changes every 3000 miles. I average about 50 miles a day and get a consistent 48-51 mpg in summer and not using the AC. In the winter in Ohio gas stations use different gas so MPG goes down to around 42 average.

Recently I've had the check engine light come on and I ran the Actron OBD-II and pulled two codes.

P1448 Manufacturer control / auxiliary inputs, auxiliary outputs
P1600 Manufacturer control / auxiliary emission controls

Does anyone know what these mean?
