lambda probe fault

[xant14]

My friend here in Sweden has a Toyota Avensis Verso 2003 petrol.
The dash has a management light on. garage says it is the lambda sond, which translated is I think the lambda probe, but there are four probes, and could be anyone of them.
Price quoted is 8000 SEK (?800) to change all four.

Are the probes the same? ie, buy one and change it individually until the problem goes away?

Can I buy the probes myself cheaper? And is it an easy job to replace?

I have a ELM OBD2 thing, and I did reset the light, but it came back on a minute later.

Any help will be greatly appreciated.

Which fault code (number) do you get? The code describes which sensor is faulty.

Thanks for the reply. I dont have the elm thing with me at the moment. So I cannot answer that. The garage gave her just a bill, no details as to which probe. They even told her all four must be changed, because they cannot detect which one it is... Do you think they are trying to pull a fast one on her?

[oldford]

Yes, I do. Or it's not a defective Oxygen sensor (lambda probe) at all, and they don't know what the real problem is.

A defective Oxygen sensor has 2 numbers in the description. A bank number and a sensor number. Bank 1 is the one with cylinder 1. Sensor 1 is before the catalyst, while sensor 2 is the one behind it. Not rocket science to identify the faulty one.

Hi

Most of the time the heater circuit do go faulty on them...........You could disconnect one at time and measure the heater circuit resistance...........But, again as mentioned by Oldford the fault code would simplify to pin point the faulty sensor............

didnt think these had 4 anyway ? dont in the uk anyway

Thanks for the replies.
This diagnostics was not from a Toyota garage. She is going to ask a toyota garage how much a diagnostics will be, and IF they can pinpoint the fault to which sensor it is.. I will get her to ask how many probes there are, and if the other garage was telling the truth about four...... ahhh, just seen your reply... smirnoff I had her raging. She has been using this garage for years.
I will let you know how things get on.
Tack sa mycket

not 100% sure if i remember correctly some fault codes may state incorrect data saying front when the problem may be a rear one and it was a toyota techie that mentioned it.

My friend here in Sweden .

1) What you moved to Sweden as 20 miles wasn't far enough from GMB45?

2) As you have an ELM thing, i agree with Ashraf184584758
about the heater.

OK, so as it is a swedish SHE, you MUST DO THIS IN THIS ORDER

1) Is she a Swedish Cheif?

2) Upload a photo of her long legs

3) Upload a photo, showing her blond hair and blue eyes.

4) pick a lambard probe at random, then
shove your TOOL up her PORT and try
BANGING her lights out.

5) Repeat experiment with unplugging lambarda
probes, one at a time untill you unplug one of them and still have ONE fault code.

(if you unplug a good one you will get 2 fault codes) - do this
to idendify the dud one - Sven at the garage must be to dumb to do this.

6) Then when you figiure out which one, CALL THE DEALER for a PART NUMBER, as it's possable it will be a 'funny' sensor.

7) Go to German SWEDISH & polish website see if they list it.

HTH

Excellent replies folks. Topped by meat heads reply as usual. Had a look in the engine bay and can clearly see the probes mentioned, thanks to smirnoff's pic. I will do exactly that with the probes, but will be in about 2 weeks when i get back.
Can't wait to get to within 20 miles of my buddy gmb.

This is for meathead.. avert your eyes other people

That's beautiful, my knob IS to big for her two holes she is showing there.

To bring this to a close, the lady took it to a Toyota garage and got it done before I got to her. Two probes and 500 notes to fix. told her she was a little bit silly not waiting, but she didn't want to get that white top of hers oily.
