most likely the pressure sensor in the fuel tank for the evap system is defective.

P0457 is a loose gas cap, P0456 is a small evap system leak. The seal on your gas cap is probably worn. Replace the cap, clear the codes with either a diagnostic tester or by disconnecting the battery for a few minutes and reconnecting it. It will take a few days for the code to come back if it isn't fixed, but that usually does the trick. I hope this helps.

When you say shakes i am guessing the steering wheel. If it is the steering wheel shaking, it's know as the death wobble. Check the front steering components, look for worn or broken parts. Most common for death wobble are the tie rod ends, idler arm and pitmen arm. look for play along the track bars and check the ball joints. The other thing too that will cause a death wobble is a bad alignment. there may be negative or no caster at all which would give you a death wobble. Check all of the above and keep me posted. Good luck and be safe

YES A CAP FROM THE DEALER WILL MOST LIKELY SOLVE THIS ISSUE...SOME OF THE AFTERMARKET CAPS ARE NOT MADE TO THE PROPER SPECS TO MAINTAIN PROPER PRESSURE/VACUUM ON THE SYSTEM WHEN THE EVAP TEST BY THE COMPUTER OCCURS
Testimonial: "Thank you- I'll try that."
