wanted ae101(silvertop) 02 sensor

[givemesideways]

hello all

just started on here the other day and already iv got the hubs and calipers iv been chasing for two months.

I am hoping to have the same luck with this search. I really really REALLY need a silvertop 02 sensor. Before you say get a new one i know how much they are(360) off toyota and a months waiting to get it from japan(or so im told). i got one secondhand one from a wreckers but when installed the car still jumps into limp mode after what im guessing is a warming up period.

any and now i mean ANY help would be FECKING brill

thanks in advance mick

No where near $360 I bought one new from Toyota just a short period ago for my AE111 and it was around $170.

Im pretty sure you can use a o2 sensor off a various toyota models.
As long as its a four wire o2 sensor. With a heater circuit?
I cant remember what model toyota o2 sensor i used on my blk top.
But i used an ntk o2 sensor. The part number is oza395- e9.

Just as an aside, an 02 sensor is not going to throw a silvertop computer into limp mode.

It'll bring on a check engine light (sometimes) but not put it in a limp mode.

There is probably something else wrong.

It'll only bring a check engine light on when you bridge the terminals in the diag box... I ran a blacktop without one for months with no issues.

What is your symptoms suggesting the car is in limp mode? Do a diag check also

[givemesideways]

my symptoms are what i thought was limp mode. Eh well almost every time i start it up(not always because some times itll start fine and then once it warms up or so it seems it) it runs uneven, is dumping fuel like there is no tomorrow and when driven it has no power really and then (because i have no tacho yet) when it gets to about 3 or 4 k revs it backfires massive and wont rev any higher. the odd time it runs in what i call normal mode it idles perfect runs sweet and revs out to the limiter without hasitation.

When i started doing this build i was not a member of dc and hadnt very much auto wiring experience even though im a sparky. i had a specilist come help me wire it from old diagrams and even though he was so maticulas be triple checking every wire both ends he had not much 20v experience.

any ideas???

the diag connection is still there but im not sure how much it is connected to sad face.

i've used a aftermarket 02 sensor before (not on a 20v) sometimes they work well - you also have to make sure they got the same perimeters and crystal then just wire it in...cheaper option with a little morefuss
but being through what i've been through i'd almost take the cover off your ecu and see if anything has happened inside, capacitors may have leaked out

[givemesideways]

thanks twisty

so what am i looking for when i take the cover ? iv had it off before but i wasnt really sure i was looking for. have you any pics at all they would help

First you need to work out your diagnosis plug and check what fault code you have if any.

If you have a check engine light connected, you just need to bridge the TE1 and E1 pins in the diagnostic connector and it'll flash any current codes.

This is what mined looked like inside but golberg has given many examples!
