Where are the sensors located on the Nissan Teana?

The sensors on the Nissan Teana are located as follows: the oxygen sensor is installed on the exhaust pipe to monitor post-combustion gases and determine whether the engine is burning efficiently; the wheel speed sensor is installed on the hub of each wheel; the coolant temperature sensor is located next to the thermostat, converting the coolant temperature into an electrical signal; and the intake pressure sensor is mounted near the throttle valve. The Nissan Teana is a mid-to-high-end luxury sedan with body dimensions of 4850mm in length, 1795mm in width, and 1475mm in height. The rear seats of this car feature additional noise reduction treatment, with air conditioning and audio controls installed on the rear seats, which also include massage functions.
I've been driving the Teana for a long time, so here's some of my tinkering experience: This car has a ton of sensors. The oxygen sensor is the most noticeable - on older models it's squatting right at the bend of the exhaust manifold, while newer versions have moved it behind the catalytic converter. If you want to check it, wait until the engine is fully warmed up, otherwise you won't get accurate readings. The air flow meter is clipped onto the front end of the intake pipe, like a little square box - last time my engine was shaking, it turned out its connector had come loose. The wheel speed sensors are hidden on the inner side of all four wheels' brake discs - after wading through water once, my ABS light came on because they got muddy. The reverse radar probes are embedded in four small round dots on the rear bumper - if you get false alarms on rainy days, just wipe them clean. There's even a rain/light sensor hidden behind the rearview mirror on the windshield - if you get window tint installed without cutting out the triangular corner, the automatic headlights will definitely act up.
My best friend just got her Teana and kept getting false tire pressure alarms. After some research, she found the TPMS modules mounted on the inner side of the wheels. This car's sensor layout is quite scientific – for example, the AC temperature sensors: the driver's side is located near the vent below the steering wheel, while the passenger's side is tucked behind the glove compartment, no wonder the dual-zone climate control works so precisely. The automatic wiper sensor is adhered to the top inner side of the windshield – something to be careful about during window tinting. The reversing camera sits near the trunk emblem; once it got misaligned by a high-pressure car wash jet, causing image distortion. The most hidden are the airbag impact sensors, concealed in grooves along the left and right frame rails – the mechanic warned never to place jack stands at those spots.
