Here's how to locate the Bank 1 O2 sensor:
1. Identify the exhaust manifold: This is the large, metal component directly attached to the engine where the exhaust gases exit.
2. Locate the O2 sensor(s): On a 4-cylinder engine, you'll likely have at least one O2 sensor on the Bank 1 side. Look for a small, threaded sensor located on the exhaust manifold.
3. Bank 1 is the side closest to the driver: Since you have a 4-cylinder engine, the exhaust manifold will be on the same side as the driver's seat. This is Bank 1.
Important Notes:
* The number of O2 sensors can vary depending on the specific engine configuration.
* The exact position of the O2 sensor(s) on the exhaust manifold may also vary.
* If you are unsure, it's always best to consult your owner's manual or a qualified mechanic.
Remember to always exercise caution when working around hot exhaust components.
