O2 Sensors

[Anonymous]

HELP!!!

I just recently paid £188 to have my 02 sensor replaced by Toyota - the car only being 5 years old I was none too impressed it had gone in the first place.

Don't know much about o2 sensors, when I put my foot down the little "kick" you get when the car takes off didn;t happen, it just died on me.

I tried again, and it did it again and this time the engine malfunction light came on and Toyota told me it had gone into safe mode.

I had it checked, replaced the O2 sensor and have given it a spin, although the engine malfunction light no longer shows the kick you get when you put your foot down still does not happen.

It did not cut out this time but instead it just coughed as if it were trying to engage but couldn't, it seems to have lost in normal power also and misses every so often.

Can anyone help please, is this all to do with the O2 sensor, or is something else wrong?    s:( s:(  

Thanks

Hi Carole and welcome to the forum, is your car using alot of oil at the moment?

How to find out what is wrong: Use a code reader, get the diagnostic trouble code(s).  Post them here, someone will advise.

In the meantime, you could try resetting the ECU by pulling the EFI fuse in the fuse block at the left side of the engine bay (key not in ignition), reinstalling fuse after a few minutes, and starting the car.  Another thing to do is clean the Mass Airflow (MAF) sensor.

Where in the country are you? If the advice above sounds a little technical (I don't mean to be rude BTW) then someone local to you may be able to help.

And most importantly is your car an SMT?

Hi,

Thanks for all your replies.  Answers below, in no particular order (well, in the order I can remember)

1)  No, it does not seem to be using a lot of oil, I checked the dip stick last night and its almost to the top, however, I have not driven it much so cannot really say, it may well be using excess oil.  I'm driving it daily now so will keep an eye on it.

2)  I'm in Leicestershire - and yes the USA is a tad far away for assistance - although the comments and advise are always useful and most welcome - thanks

3) No its not an SMT

4) Thanks I'll try pulling the EFI fuse.  My local Toyota garage have just used a diagnostic reader, which is when I had the O2 sensor replaced, but it does not seem to have solved the problem - do you think I could ask them to check it again, don't really want to have to pay another £40 though, don't see why I should have to   s:!: :!: s:!:  

What I would really like is a manual - I swear by my Haynes manaual, I've always had one for every car and even if I can't fix it myself, which I have been known to do, at least I can tell if I'm being fobbed off by a garage - which unfortunately when my car was in a recent accident the repair garage tried to rip me off - backfired on them, I may be blonde but I ain't totally dumb!!    s:) s:)

99% of us are in the UK, though  s;) s;)  (There's only Beanie and a few others from the US on here)

Unfortunately there's no Haynes for these cars - the closest you can get is getting a copy of the BGB (Big Green Book - offical Toyota service manual) - it's really not that much more technical than a Haynes book anyway (which instils so much confidence in Toyota mechanics....)

I had to pay to have my codes read one time and it cost more than it did to buy the code reader.  They are very, very easy to use.  Plug it into OBD-II port, press a button, it shows you the code(s).  Then you can either look them up (they are standard) or post them and someone will take a wild @$$ guess as to what it might be.  We are very often right.   s:) s:)

Sounds complicated. Mine doesn't have any buttons, you just plug it in.  s:lol: :lol: s:lol:
(and leave it in for x seconds, if you want to clear any codes)

Hi

Not meaning to thread hijack here!

We took the girlfriend's car to get the codes read and it turns out that it's the O2 Heater Sensor (Bank 2, Sensor 1) that is making the engine management light come on.  We have been quoted £207.31 to buy the part and have it fitted   s:shock: :shock: s:shock:  

Does that sound about right or a bit steep?  Her car is using quite a bit of oil as well, so what would that mean?

Cheers for any help given.

Nope! EXACTLY the same problem I had with mine yesterday and going back tomorrow to get it fixed. Costing me £185 and it cost me £89 yesterday just for them to have a look at it. Combined cost? About £260!!!  s:shock: :shock: s:shock:  

I just don't have the oil consumption, thats all. Which is a good thing...........phew!

I just want to let you guys know that I purchased my O2 sensors from sparkplugs.com. They are Denso just like the factory but because they are universal there is some assemble required which is easy because the color code is the same and the O2 sensor comes with all of the crimps, instructions and a tube of anti seize.   I paid $45 in the US for them and I don't know how much shipping would be to the UK but if it's reasonable it would be much cheaper then the same parts from the dealer.   Assembly is very easy even if you are not the do it your self kind of person.   s:D s:D
