I have been searching for how to replace bank 1 sensor 1 for my Camry 2010 V6, I have replaced b2s1 while I was on it, but had a hard to even visually see the b1s1.
I have removed the air cleaner to free up some space, I assume it is at the back of the engine, but can barely see anything like a sensor be peeking from side.
Do i need to remove the manifold? If i do, will it be super hard to change - I’m worried about the limited space behind the engine.
I am almost there don’t want to give up and send it to a mechanic
Thanks in advance for your guidance.
