Hello group,
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
Are you only working from the top? Jack the car, place it on stands (safety first) and crawl underneath. I’d bet you can see the sensor. YouTube vids from an earlier Lexus ES 300 and V6 Camry show it being removed from below. Breaking it loose could be a challenge…
