On a 2005 Chevy Colorado with a 5-cylinder engine, the oxygen sensors are typically located in two places: one is upstream (pre-catalytic converter) and the other is downstream (post-catalytic converter). The upstream sensor is situated on the exhaust manifold or just before the catalytic converter, while the downstream sensor is located after the catalytic converter in the exhaust pipe. To access them, you may need to raise the vehicle for better visibility and reach.

O2 sensor in the exhaust manifold near the engine

oxygen sensor is usually in the rear of the exhaust maifold or in the exhaust pipe itself
Bank 1 is the bank of cylinders that contain cylinder 1. The O2 Sensor 1 is the O2 sensor located in the exhaust system between the cylinder head and the catalytic converter, also known as the "upstream" O2 sensor.
The oxygen sensor on a 2008 Chevrolet Colorado is typically located in the exhaust system. There are usually two sensors: one before the catalytic converter (upstream) and one after it (downstream). The upstream sensor can be found on the exhaust manifold or just after it, while the downstream sensor is located on the exhaust pipe after the catalytic converter. To access either sensor, you may need to lift the vehicle for better visibility.
On the exhaust pipe It is before the catalytic converter on the same side as cylinder #1.
Oxygen sensor is located at the exhuast Manifold.
Bank 1 should be the side of the engine cylinder #1 is on.
The front oxygen sensor is located on the exhaust manifold of the BMW 318ti. The rear oxygen sensor is located in the head pipe.
If your 1988 Chevrolet Celebrity has the V6 engine the oxygen sensor is in the middle of the exhaust manifold nearest the firewall. If you have the 4 cylinder engine the oxygen sensor is located in the exhaust manifold just above the exhaust pipe flange.
The cylinder position sensor is located in the distributor.
