error codes

both are for Evaporative emissions system (EVAP). P0441 is incorrect flow detected. P0455 is for a large leak. I would start by checking the gas cap and clearing the codes. Then wait to see if they reappear. Did they come on right after you filled the tank?

When you changed the gas cap, did you get an oem one or a different brand? sometimes the off brand ones seem to cause issues with the rav4. Did the lights come on after refueling? Or just as you were driving? And are there any other codes? It seems odd that the EVAP system would cause the VSC and AWD lights to come on as well...

Are there any error codes relating to the VSC or AWD lights?
