Hello, Here is a guide that will help you replace the oxygen sensor in your car. The number one cylinder which is bank one is the left side of the engine if you are looking straight onto it. (right side of engine)https://www.les-grizzlys-catalans.org/articles/how-to-replace-an-oxygen-sensorYou may need to jack the car up.https://www.les-grizzlys-catalans.org/articles/jack-up-and-lift-your-car-safelyHere are the locations to all of the o2 sensorsCheck out the diagrams (Below)Please let us know if you need anything else to get the problem fixed.Cheers

Which sensor are you looking for and why? Do you have a code or something? The sensor is rarely at fault.Read the guide below on oxygen sensor replacement..https://www.les-grizzlys-catalans.org/articles/how-to-replace-an-oxygen-sensorMost of the time the oxygen sensor codes are consequential of other issues.. vacuum leaks are a big oneThe upstream sensors are located in the exhaust before the catalytic converters... the downstream are after the catsJust because they are inexpensive, don't just throw parts at the vehicle, it may not fix it
It was tested by auto zone and checker auto parts. Did not write down which one needed to be replaced, replaced wrong one. Trying to figure out where both are located in the vehicle so I know where the other one is.
You"re likely replacing the wrong part anyway. Most 0/2 codes are not caused by the sensors. We would need the exact code number to even identify which sensor it is. It could have 4 of them.
Received code 1130 from mechanic. Came up catalytic exhaust performing below threshold. Saying bank 2 sensor bad. Where is this and does this mean a catalytic converter is bad or just the sensor?

Fault codes never say a part is bad or needs to be replaced. They only indicate the circuit or system that needs further diagnosis. While it"s true you will find the sensor in question to be defective about 50 percent of the time, there are a lot of other possible causes for codes to set.Bank two is on the passenger side. Most systems have an upstream, (closest to the engine), and a downstream, (behind the catalytic converter) oxygen sensor on each bank. The downstream one is just for monitoring the efficiency of the converter.The code description I have is more informative.P1130 Lack Of HO2S-11, Fuel Trim At Limit.It suggests the Engine Computer is trying to correct the fuel / air mixture and doesn"t have enough adjustment capability to reach the correct ratio. That suggests the oxygen sensor is not defective; it"s just reporting what it sees.
