I was recently getting DTC P1490 and the car was taking some time to get to temperature. I called a dealership as the P1490 is a dealer code. They told me to change the thermostat, which is what I suspected. I did so and this fixed the problem for about half a tank and the light is now back on. This time I get a P1490 as well as a P0420. The car seems to get to temperature in the right amount of time but I am not 100% positive. It takes around 5 min of driving to get it to the normal reading on the temp gauge. Not sure what I should do, Replace the tstat again or take it to a dealer and have them read the codes for 45$ and have them tell me whats wrong with it.

Any help would be appreciated.
