About a "good long drive" I drive this car as my commute to and from work everyday. This commute is 27 miles each way totaling 54 miles daily.
This commute is 6 miles city and 21 miles highway twice a day. At highway the speed is around 70 MPH
I don't know how accurate this codes are because the car was scanned at my local Autozone and I double checked at Oreillys. Both found the same codes.
Around one year ago the same car had an issue of not getting acceleration even when accelerator pressed to the bottom. The tachometer was reaching the maximum of 2100 RPM and the speed goes only at 65 mph. One European shop repair found a defective electric throttle stuck closed. This throttle has an electric motor and this motor got bad and caused this problem. Now the car is again reaching the maximum of 2100 RPM. Can DEF cause this kind of problem?
After this part replaced the car ran good again. Even my transmission worked better after that .
My question about the DEF is because the scanner found this code but personally I don't know the symptoms of the DEF restriction.
Thanks for your reply.
