Hi Guys,
My next challenge. Clean the MAF sensor and throttle body. Can someone please point out where MAF sensor is located on the 2011 ES350 engine. I am thinking it is right next to the PCV valve. Can you please confirm it?

Thanks for the help in advance.

They are usually inside the air intake tubing close to the throttle body. It involves taking stuff apart and looking for it. This youtube video should help as the Camry is the same except the Lexus has extra panels covering the engine.

 

Thanks Clutchless! Found it and cleaned it. Fairly easy once you know where it is

But, here is an interesting problem. I used the CRC MAF cleaner to clean it as it was suggested in the above video, as well in a bunch of other youtube videos - like a genius I am without reading the instructions first. The instructions clearly state the following:
"DO NOT use on vehicles with Karman-Vortex airflow sensor, e.g. Toyota Supra turbos, Mitsubishi's and most Lexus vehicles."

Should I be worried? Haven't started the car yet, but installed the MAF after cleaning. What should I do now?

 

Start the car and drive. It's too late now. Either it starts and all is well or you have a problem. I bet it starts just fine and that nothing was damaged. One cannot group all Lexus vehicles together without also including all Toyota vehicles as they all share the same engines.

 

Started the car. No hiccups, no noise, no engine light. The car is running fine! I wonder why the MAF cleaner specifically states "most Lexus vehicles excluded" but not Toyota vehicles as they both seem to use the same/similar parts?
