& are you using E10? If you are , STOP IT!!
I get bucket loads O2 code`s when it`s the fuel to blame.

Hey mate,

I wouldn't say the engine was loaded as such, as it seemes to light when cruising with a steady throttle. Even changing up and down through the gears (ie revs increasing or decreasing) didn't change much. It seems to remain on until my speed falls down to 60-70kph or thereabouts. Like I say, its a little random and I cant get it to play up on demand. The only consistancey is that I've only had it light at higher speeds.

Should it be the o2 sensor, I still have the Bosche universal part # you gave me as opposed to buying the $$$! suzuki part. Where exactly did you order yours? Can any local parts shop get that kind of thing in?

22mm spanner or a metric shifter will do it!

And I assume this is what we are all talking about?
You know... that thingamebob attached to the doseewhatsit.

Hi Stuey, Can you tell me how you got the flash code to come up?

My 4WD has exactly the same problem you described, engine light comes on, usually around high way speeds and then will eventually go off by itself. Sometimes it will do it a few times in a trip and sometimes it will never come on. I just got back from Kingscliff to watch the wrc and the light never came on so I thought "Great, a good run has fixed the problem" - then the other day it came back on again

I have played around with low and high octane fuels but havn't found anything common.

Please keep me posted with how you go.

cheers
Mike

For the record, mine turned out to be a faulty coil pack, not an oxygen sensor. The oxygen sensor was throwing up the code, but is was caused by an incorrect burn in one of the cylinders due to the stuffed coil pack. If you still need the codes sent through, I can..... but I'm sure Gus will sort you out.

Reckon you can re-attach that word doco for me Atari? Got wiped during the forum issues it seems.

Thread revival, almost 12 months later I finally got around to shorting that pin and getting the error code

Sure enough, I'm getting error 13 also (that said - it hasnt flashed in months).

Does someone have the Bosch part # they can give me for the universal o2 sensor? Couldnt find it in this thread of any other related ones.

cheers

I replaced the one my J20a with a universal Bosch O2 sensor, I'm guessing yours is a 4 wire heated sensor?

The part number was # 0258986507775 it was around $100 instead of $300+

Hope this helps.

I have just been through the 02 (Lambda)sensor hunt for my GV. Here is what I found.

OE sensor for V6 GV is a NTK (Same company who make NGK spark plugs) OZA 536-J1 this has been superseded by OZA 495-J2 ($85.60 veale auto parts)

Same sensor as above but from Goldy Suzuki $420

Universal $132 ( The universal require wire to be joined and original plug reused)

These are all Zirconia 4 wire heated sensors. Life expectancy ranges from 50K to 160K depending on size and type. O2 sensors do need checking as with spark plugs. They tend to start slowing down and not sending the signal to the ECM quick enough which results in incorrect fuel air mixture. I found with my sensor it had stopped sending any data at all so the ECM was leaving it on the Idle mixture. Which is why it was using more fuel than normal.
