How to remove the EGR valve/cooler

I need to replace the EGR vavle and maybe the cooler.. The problem is that a tutorial I watched is not the same as my year and I don't see any videos of a layout like my 2016 Prius hybrid.

Directly to the right of the EGR on my car is the inverter which seems to be in the way. Will I need to remove the inverter to replace the EGR vavle?

Thank you.

 

150,000. I took a putty knife and blocked the path of the EGR took her for a test drive and the problem immediately went away. No more shaking on acceleration.

 

Also I want to add that I recently changed the oil and may have overfilled the oil then put about 600 miles on the odo. I read somewhere that if we go by the dipstick it is overfilled and to fill it 3/4 below the full mark is a good practice but I filled it to the full line. I already bought the part 04004-58137 for $250 annd this is just for the valve. Before I proceed I just had a few more thoughts and questions.

Based on what you shared I could be wasting my time and find a squeaky clean EGR valve since the gen 4's really shouldn't have a problem with clogged or sticking EGRs..

Is is likely that my EGR could have gotten prematurely clogged at 150k because I overfilled the oil recently ?

Do you believe my diagnosis is conclusive enough to move forward with replacing the EGR valve?

Do you think I need to replace the cooler also?

What else could it be based on the test I did and how it ran with a bypassed EGR?

Thank you
