Here are some steps to help you locate the oxygen sensor in your Toyota Passo 2007:
1. Park your vehicle in a safe location and turn off the engine.
Allow the engine to cool down if it has been recently running.
2. Open the hood of your vehicle.
Locate the hood release lever inside the vehicle, usually near the driver's footwell, and pull it to release the hood. Prop the hood open with the support rod.
3. Locate the exhaust manifold.
The exhaust manifold is a part of the engine that collects and channels exhaust gases away from the engine. It is usually located on the side of the engine block.
4. Follow the exhaust pipe downstream from the exhaust manifold.
The exhaust pipe carries exhaust gases away from the engine and towards the catalytic converter. The oxygen sensor is usually located somewhere along the exhaust pipe, before the catalytic converter.
5. Look for a small, cylindrical sensor screwed into the exhaust pipe.
The oxygen sensor may have one or more wires connected to it. It is typically located closer to the engine than to the catalytic converter.
If you are still unable to locate the oxygen sensor in your Toyota Passo 2007, consult your vehicle's owner's manual or seek assistance from a professional mechanic.
