Hello, I'm looking to see if anyone has any advice on removing this sensor and hose on the power steering pump of a 2004 Lexus es330

 

Hello,

Not sure about 4th-gen, but in my 2000 ES300 I was able to use a deep socket with a very long extension and u-joint to unscrew it from the top of the engine. You might as well try it, if that won't help, you will likely have to get at it with a stubby wrench or something similar.

Hope this helps and best of luck!

 

I did it with 24mm box wrench from under, disconnect the sensor first

 

I was going to suggest that, glad you figured it out. If the replacement hose came with a new washer I suggest using the original instead.
