Yey engine light on, bank 1 sensor 2!!

tested the Ohms on a volt meter and its the post cat left hand sensor as you look at the engine so drivers side of the engine...

now there what �160 at toyota �222 online at some places... but.....

I am sure I have seen 'Denso' on some parts on the bus, would these sensors be ok? seam a fairer price, still nearly �60 mind!

Cheers

my thoughts would be if its the same size thread tipe it will work, but you might find the one you got just needs taking out and cleaning over night in some thiners or something

done a resistance check on the two lower lambdas, ones pulling 28-32 ohms when tested, the other is strugglig to pull 13ohms so it looks like the sensor is dying.

I need to find out the toyota part number of the lower sensors as the company selling the denso ones gave me a list of compatable toyota numbers the sensor will work with!

I have seen a picture on a toyota website showing all 4 sensors part numbers, but can i find it now?! lol

so does look like the sensors heater wire is failing hence the P0141 fault code illuminating my dash  Cry

got the part number via a mobile phone camera and grazing my hand on the rad lol

89465 28290 and its a denso one.

So looks like i can get a denso one delivered for under �80 and a mates allready said he can get the old one out lol

Then its like for like and shouldnt confuse the ecu or anything and is half the price toyota want for the same brand sensor....

Then ill either disconnect the battery for 5 mins or so, or borrow my mates OBII scanner again to reset the ecu..... And I will buy a OBII scanner later in the year lol

going back on subject was looking at your earlier posts and you said that the sensors had been done before you got it. If its got a recipt for it being done at a garage you might be able to take it and ask them why they gone again.

i would phone and ask how long they should last just to be cheeky. paying that much every two years is a bit much but then theyprobably lied when they said they changed all four. just the sort of thing i expect from any garage

well was a toyota garage so your probably right  Grin

I got the price down to �71.76 on special delivery so doesn't hurt as much. I'll order it on tuesday.

Wonder if its worth starting to spray some penetrating on the duff sensor or not while I await the sensor? As its on the manifold/cat down pipe, I know it'll burn off, but will it actually do any good in the process?!

Give it a spray and have a go at undoing it once its losed will save the job when the new one comes. I wouldn't have thought it be that bad if it has only been in for two years.
