I need to replace the first oxygen sensor, which is located on exhaust manifold behind the engine. But how to reach it? I've tried both from below and from above with the engine rotated as much forward as was possible but no luck. The only way I see possible to make enough space is to remove the ignition coil, but I don't want to take that step without knowing it is right thing to do.

I recently had a check engine light, VSC off light (blinking) and traction control light come on. I took it to Autozone and had a p0037 code ring up for a new Bank 1 Sensor 2 oxygen sensor (downstream). I believe I have found the correct sensor (located under car, approximately near drivers seat) and it looks simple to replace, aside from the fact that the wires go through the car body.
Can confirm that I have located the correct sensor? And if so, what is the best way to get to where the wires connect?
Is it located under the drivers seat? What should I do about the rubber grommet located under the car where the wires appear to pass through?
The service truck threw a CEL, and i pulled oxygen sensor performance bank one sensor one code. That would be driver side sensor between the manifold and cat, rite? Don't want to change the wrong one...

We took our 2008 Prius in for a check engine light. The dealership said oxygen sensor was faulty. Changed that and had them change the serpentine belt while there due to cracks in the belt. My wife filled up the car the next day ( it took 13 gallons) but gas gauge was not registering a full tank. We drove 67 miles and I decided to pull into a gas station and see how much it would take since the gas gauge was not working properly. It took over 7 gallons.

View 10 RepliesI have a 1998 Nissan Altima (manual transmission). The "Check engine light" came on. The oxygen sensor went bad again. I have had this repaired twice (to pass inspection). Every time I get it repaired, I take the car back to the inspection station and then it passes inspection. But in a few weeks to a couple of months, the "check engine light" comes on again. Every time I get this repaired its almost $400-$500 expense. I should probably take the car to another mechanic this time.
View 1 RepliesI have a hyndai Sonata v6. It is 2006 model and has done 86K miles. It recently failed the inspection and I was told it has faulty oxygen sensors. I have replaced the sensors. But now I am advised by the mechanic that I need to drive abut 200 miles before I can take it for the inspection again because it takes some time for the sensors to get adjusted. Is that true ?
View 7 RepliesHad my catalytic converter stolen, along with the trailing O2 sensor. Muffler shop replaced the converter but did not have the correct sensor so had to order it. My understanding is that the trailing sensor is used to assess the efficiency of the converter. I have the leading O2 sensor installed and the car seems to run fine. Driving a 2005 Honda Element 5 speed. Question: am I running the risk of damaging the engine while driving it without the trailing sensor?

View 3 RepliesI have just replaced an almost new oxygen sensor on my 2000 Grand Am. After about 40 miles, the check engine light came back on again. I have not had a chance to check it, but I assume it is the oxygen sensor again. What am I missing?
View 1 RepliesI have a 2001 Mazda Protege LX 2.0 with 121,000 miles. I removed the front oxygen sensor today to replace an exhaust pipe, and I noticed that the tip has a red/pinkish color on one side only. What this would indicate?
The only thing I could find online is that a pink tip indicates lead in the fuel. This is impossible, since the only gas station I frequent is a Conoco which is always very busy. Plus, I haven't noticed any performance issues from bad gas, and not to mention the fact that leaded fuel has been completely phased out for 15 years. What's weirder is that the sensor tip is only pink on one side - I'm guessing it's the side that's facing the exhaust manifold.
I thought this strange occurrence I am about to describe was maybe happening because of a faulty air-fuel oxygen sensor, that I knew was bad do to a code test that was done, when my check engine light came on. However, after changing the air-fuel oxygen sensor, doing a reset on my check engine light over the weekend, this same occurrence is happening, to spite the check engine light remaining off. Here is what is happening.
When I start and drive it to normal driving temperature then put the car in "Park" with nothing turned on, the car will shake the idle speed will move up and down until it will eventually kill.
Special Note: It does not always have a idle drop and kill the engine every time. If I turn the A/C on in "Park" it idles up higher and does not ever kill. Could it be a bad Idle Air Control Motor?
I recently bought my new (For me) R32, the first owner of the car remove the 2 catalyst from the car and now I have the check engine light on. When my friend put the vagcom on the car it shows an oxygen sensor fault. What can I do to fix this? can I just buy a MagnaFlow exhaust?
View 11 RepliesI've been looking online to see how often you need to replace the oxygen sensor for the 3rd gen Prius. I can't find anything online. How often you replace these? Would it be around 100,000 miles or more because it's a hybrid? Also how many are there? I've heard there is 2 and some say there's 4.

I have just bought Denso 234-4305 Rear Sensor but I was wondering if there are any guides to show where it's located?
The only guides I found is for the 9th Gen Corolla.
The Car has 88k miles on it so I guess it's outside the emissions warranty. Thus what is the price of a new ECU just in case that's the problem?
My Jetta has been throwing this code on and off for over a year now. It used to only come on when it was really cold with wet roads. Now the code will randomly come on in any weather. I usually just clear it but it's coming on to often now. I don't notice any performance issues or gas mileage problems.
Scan shows : Trouble Code - P0420 Catalyst System Efficiency Below Threshold (Bank 1)
I've been reading and apparently 1.8t engines only have One bank? I'm assuming this the the front 02 sensor throwing this but not sure?
I have an aftermarket exhaust/high flow cat. Apparently this can be caused by a high flow after market catalytic converter and one solution is to use a test pipe or spacer to move the rear O2 sensor further from the exhaust gas flow. But I'm not sure this is the issue since I think it's my front sensor throwing the code? That's not by the Cat is it? I just don't want to have the sensor replaced to have the code still come up.
