My Highlander (4 cyl version) threw a P0141 ODB2 code (Bank 1, Sensor 2). I bought the new sensor, but when I went to install it, I noticed the repair manual I have doesn't exactly show my year exhaust components (it shows a 2005 4-cyl, which I guess is different or the manual is wrong). So, where is it exactly located? Looking down into the engine compartment, I see two sensors right after the exhaust manifold, then two right where the path slinks to the underbelly of the car. My guess is it is the one near the ground on the right side (if you are at the front of the car facing the rear). Thanks for the help!
