My wife's GS 350 threw these codes while I was pumping gas last week. I cleared them and put a new gasket on gas cap and they went off for about 100 miles then popped back up. I cleaned throttle body and MAF sensor and they are off again. Anyone else had any experience with these codes? Wondering about O2/AF sensors and the fuel pressure sensor. I had the gasket replaced on FPS on a recall about 2 months ago.

 

When fuel pressure sensor goes out it won't crank and cooling fans run constant.
My guess is MAF, amazon has them for 80. Fixed my lean bank 1 code.
You can get a Bluetooth aldl and app to view your 02 sensor readings/codes on your phone for $25.

 

Sounds cool, where can you get it? What is it called?

 

And this is the app you need.
