So make sure check out your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Lexus RX to your mechanic.
  • EGR valve: The EGR valve has the benefit that it is often times easy to access and simple to take apart/clean. You can always take a look at it and clean it, for this see our article on cleaning the EGR valve of an Lexus RX.
