Prius (2004-09) :: Faulty Oxygen Sensor Caused CEL To Came On
Apr 10, 2016
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.

I have a 2004 Corolla with a Check Engine light on. The Toyota dealer diagnosed this as: "Oxygen Sensor Bank 1 Sensor 1 - slow to respond".
The diagnostic code is PO133. Elsewhere, I find that this code indicates:
The oxygen sensor is faulty.
The wiring to the sensor is broken / frayed.
There is an exhaust leak
Haven't noticed exhaust leakage, and I doubt the wiring is faulty.
1) Where is sensor 1?
2) Do I really need a new sensor, or can I clean the old one?

I 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 ?

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'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 just posted last week that my check engine light was on and the dealer wanted to replace fuel injectors. But after the fuel throttle was cleaned and oxygen sensor was replaced the check engine light went off. However, yesterday the check engine light came back on. I am talking it back to the dealer, in a couple of days. Where can I go to get to get the error codes read so I have them before I go back to the dealer? Around 128,000 runs fine, around 40 miles per gallon. Last time I had the oil change dealer nothing came up on the 30 point inspection.

What can be done regarding these faults? P0037 and P0057
Description:
Oxygen Sensor Heater Control Circuit Low (Bank 1, Sensor 2)
Oxygen Sensor Heater Control Circuit Low (Bank 2, Sensor 2)
The catalytic converters have been removed but the fault was present before that anyway. All I want is the VSC function to work again and the lights to go off. I have heard you can put dummy sensors in.

I have a 2010 Toyota Corolla 1.8L, the base model.
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?

My first Prius, an 05 has 249K and performs pretty much flawlessly. My second, an 04 which I purchased in May, has 75K. While driving the 04 yesterday, all the lights came on the dash and really scared me. I immediately pulled off the road and checked belt, fluids and anything else I could. I then called the dealer and they thought since the car was running normal, to bring it in. For a hundred dollars I was told the HV battery, though working and not a problem, would have to be replaced due to a faulty "battery temp sensor" and that this part is not repairable....I need a new battery! Code POA9B ... Tomorrow I am taking the rear panel out and check the HV battery fan, etc. Can I drive the car with these lights on? Everything seems to work but the CC.

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.

How do you replace an oxygen sensor in a 1997 Cadillac Deville? Where is it located?

I 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.

Had 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?

I 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?

I 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.

It's a 2006 with 135K. About 3 weeks ago I had a tire separation that caused significant body damage to the bumper and left front fender. I had the tires replaced, but left the damage, for now, as it's only aesthetic.
