On a 2003 Lexus, the oxygen (O2) sensors are typically located in two main areas: upstream (pre-catalytic converter) and downstream (post-catalytic converter). The upstream O2 sensor is usually found near the exhaust manifold, while the downstream sensor is located further along the exhaust system, after the catalytic converter. Exact placement can vary by model, so it's advisable to consult the vehicle's service manual for specific locations.
A/F Sensor for Bank 2 Sensor 1. It is the O2 sensor on the front manifold.
It is a real pain. My suggestion is to take it to a shop.
On a Lexus IS300, the O2 sensor signal can typically be found in the engine bay, connected to the exhaust system. The upstream O2 sensor is located in the exhaust manifold or just after it, while the downstream sensor is located after the catalytic converter. You can access the wiring harness connector for the O2 sensors by following the exhaust pipes and locating the sensors. For precise identification, consulting the vehicle's service manual is recommended.

You can find O2 sensor wiring diagram for a 2003 Tiburon GT in the owner's manual. You can also find it at auto parts stores.
The O2 sensor on a 2003 Cadillac Northstar engine is located in the exhaust manifold. The readings from this sensor are sent to the vehicle's computer, which makes constant adjustments to the fuel and air mixture.
To change the O2 sensor on a 2003 Suzuki XL7, first ensure the vehicle is cool and disconnect the battery. Locate the O2 sensor, which is typically found on the exhaust manifold or downstream in the exhaust system. Use a wrench or O2 sensor socket to unscrew the old sensor, then install the new sensor by threading it in and tightening it securely. Finally, reconnect the battery and check for any warning lights on the dashboard.
Stop by your local AutoZone. They will hook it up to a handheld tester and print out which oxygen sensor is failing.
