I have owned a 99 RX for the last 1.5 years and it now has 95K miles. About 90K the transmission had to be replaced for $3,500. Other than that it has worked well for myself and the previous owner with only the normal maintenance

couple days ago my CEL illuminated and the VSC is intermittent as we know is an issue with this year of Lexus. I got the codes from a dealership and they came back P0125 and P1155 and recommended to replace the front two sensors. I have tried the gas cap, fill the tank, check hoses but I am reluctant to replace two sensors at once as it seems to be a chain reaction. Any thoughts? Which of the two sensors would you replace first to see if that helps? Thanks all
