Oxygen Sensors

Bank 2 is opposite of where cylinder 1 is. Sensor 1 is before the catalyst.

There should be plugs where you unplug your old o2 sensor plug at. If you havent done that then just follow the wire from the plug.

Usually oxygen sensors are what would be screwed into the exhaust manifold.

tells the computer in the vehicle how much o2 is leaving the engine so it can tell the intake valves weter to add more or less gas into the cylynder

Down stream of the engine in the exhaust manifold. Start at the engine and follow the exhaust pipe back to the catalytic converter, there is usually one before and one after.

it is false economy to do that. the sensor is probably gone too,or on its way out. buy a new sensor. it will pay for itself in the long run.

If you smell gas on cold start up and you may see black come out of the tail pipe after a short engine rev. Even if your engine check light does not turn on change your o2 sensor or sensors. Especially if there is allot of km/miles. Do it your self it is stupid easy. Then do a computer reset for your car (go to YouTube type how to reset the car to get rid of chech engine light. It will be something like turn you ignition key till the lights come on do not start it, pump the gas peddel three times the the computer resets its self.

If you smell oil and you will smell a sharp strong smell and see oil it is purple blue when burning on a cold start and at stop and go driving.

Have a buddy follow you they will see the exhaust floor the car to build up allot of compression. If black smoke is seen it is fuel mixture. If your car is fuel injected it is o2 sensors. To see some soot on tail pipe is ok to smell and see it you should fix it for better gas mileage.

Purple smoke well scrap the car sell it for parts.

An O2 sensor circuit may show no activity due to several factors, including a faulty O2 sensor itself, damaged wiring or connectors, or issues with the vehicle's engine control module (ECM). Additionally, a lack of power supply or a blown fuse in the circuit can also prevent the sensor from functioning. If there are exhaust leaks or improper air-fuel mixture, these can affect sensor readings, leading to no activity as well. Proper diagnostics are essential to pinpoint the exact cause.

TRUE

Some manufacturers state that it is a general tune-up item that should be changed every 40,000 miles, while others have different criteria. It is best to look at the service schedule for your vehicle to determine when it needs to be changed.

Yes easily

Bank 2 Sensor 1 is typically located on the exhaust system of a vehicle, specifically on the side of the engine that does not contain cylinder number one. It is positioned before the catalytic converter and is responsible for monitoring the oxygen content in the exhaust gases, helping to optimize fuel efficiency and emissions. This sensor plays a crucial role in the vehicle's engine management system.

Pop the hood, look down between the radiator the the front of the engine. should be plugged in the rusty exhaust pipe with an electrical cord that should be purple going to a plug on the right side of the engine.

Some are and some aren't. There are different variations of oxygen sensors. First you have narrow band and wide band O2 sensors, then you have heated and unheated O2 sensors. Unheated sensors can have 1 or 2 wires , while heated sensors can have up to 5. Also some sensors are specifically calibrated to the unit they are intended for, so unless you really know what you are doing, then no they are not interchangeable.

There are two, one on each side of the catalytic converter on the back of the engine.

Nothing :d

Not so sure that's true. Improper voltage or short circuits can affect the sensors functions which can give false readings. Always check your circuits before replacing your sensors.

Measures the amount of oxygen in the exhaust

It measures the amount of oxygen in the exhaust stream. The computer uses that info to adjust the amount and timing of the fuel injection system to achieve the best emissions, power, and fuel economy.

Your best bet is to replace it when you can. They are like spark plugs. Cleaning them may only be a tempory fix. If you feel you wan to clean it, though, use a can of propane and run the flame over it from about 2-3 inches away from it. Normal colouring for an O2 sensor is the same as older spark plugs: a light tan colour.

Passenger side and after the catalytic converter O2 sensor.

Bank 1 sensor 1 on a '02 Suzuki XL7 should be 5.0 - 6.4 ohms. Looking at the connection with the undo clip pointing down, do an ohms test between the two top prongs. These are the 2 heater wires for the O2 sensor. Depending on manufacturer they will most likely be either 2 white or 2 black wires.

depends on the kind of car

My car is putting out too much petrol. It blows smoke. I repaired everything and I think it might be a sensor. How do I get the right amount of fuel distributed and where?

No, bank 1 sensor 1 can not be used in place of bank 1 sensor 2. There are generally completely different part numbers and need the exact one they are asking for.
