Check Engien Light
 

Hei, my check engien light is worker in my car. and I have found out that it's p0130 - Oxygen sensor (OS) or OS circuit.

Also my CO% gass whas to high, 1,57 % to be exactly, and should be 0,5 %

Can all this come from the Lamdasond?
Or do some one in her know what det problemt can be?

The spec's on my var :
3" all the way from the turbo. New Intercooler. Open Air filter K&N. 0,5 Bar Turbo boost.

Sorry for bad language :)

Mvh

RE: Check Engien Light
 

Do you still have a catalytic converter on your car? Yes, the O2 sensor is probably at fault here, but if you don't have a cat it might also be the cause.

RE: Check Engien Light
 

Yes I have cat on my car, and I have checked every silikon house for leeks on the car, and have found no one, but I don't want to by new lamda if it's not the lamda who is broken, you get me? :)

The car works perfectly normal, I dont notis anything at all when I am driven, exept that its using VERY mutch Gasolin !!!!!! The drivingcomputer goes of the hills with the numbers.

Again, sorry for my bad English.

RE: Check Engien Light
 

It is possible that this code is indicating something else. Try to check the 02 sensor wires for continuity with a multimeter. Also I'd check the fuel pressure to see if it's low by any chance. That code can be triggered by that.

RE: Check Engien Light
 

Okei, how can I check the fuel pressure? Do I ned anny special tool? or do I need a Gauge?

RE: Check Engien Light
 

yeah, you need a gauge. There's a valve that you can attach a gauge to. The location varies, but it's either at the fuel rail or at the fuel pressure regulator.

Hello Docen. If you don't mind me asking, what is your mother language?

RE: Check Engien Light
 

Okei, Thanks Roto :)

My Mother language is Norwegian :)

just one question:
If this problems that you are saying I should check is allright. Then it's guaranteed that it's the Lamda, 02 sensor?

RE: Check Engien Light
 

Nothing is ever guaranteed, but it may be the case...also try to take the sensor out and wire-brush the bung. It could just be a bad ground.

RE: Check Engien Light
 

could it be the amm causing him trouble with codes

RE: Check Engien Light
 

Okei, I shall try all those things you have taken up :)

But since my Co gass % is sow high? And It uses so mutch fuel, what are the sympthoms? I thoug of what you sad, and if the fuel pressure is wrong, wouldnt that be noticed when i drive the car in any way?

Like I sad, I do not get any problems while driving, other then it uses mutch fuel. and the light is there, and my CO% is to high.
It should be 0,5% And now it is at 1,57 %

RE: Check Engien Light
 

I'm no emissions expert, so I can't tell if increased CO is a sign of running rich or lean, but increased consumption points to rich. If that's the case you also might have a stuck open injector. Pull the spark plugs and take a picture of them to post here.

RE: Check Engien Light
 

The plug color is normal, Light Chocolate brown. But her is the pic. (not the best camrea)

RE: Check Engien Light
 

Are all of them the same?

RE: Check Engien Light
 

Yes, All 4 !

RE: Check Engien Light
 

Take the sensor out and try to rattle it. If there's something rattling inside than it's definitly bad.

RE: Check Engien Light
 

Okei, I'll try that tomorrow, and I just have to say that I am very glad for your expertise !!

Thanks !:)

RE: Check Engien Light
 

Hey, Nothings rattling inside of the o2 sensor !

On my car there should be a 4 wirring sensor, right?

Did I mention that my Driving computer is showing VERY high amount of fuel per 100 km. So mutch that in fact it's not possibel to use that mutch fuel.

And since I don't notis anything while driving the car? just that the chek engien light is there, and the Driving computer is over the hills !

My plugs seems fine. And like I sad, the car acts perfectly nomal while driving, I have to fix this because of the Eu-chek.

Can it be my cat is broken? exhaust leeks? something else?

RE: Check Engien Light
 

Yeah, yours should be a 4-wire sensor. Have you tried resetting the ecu by disconnecting the battery?

RE: Check Engien Light
 

No, should I do that whit taking the minus pole off in about 10 minutes? and then put it back on ?

RE: Check Engien Light
 

High CO indicates a rich mixture. So the failed emissions and the increased fuel consumption are related. Now its just a matter of "why". It is possible that the Lambda sensor has failed and is falsely telling the ECU to add fuel. Poor grounds and poor connections can cause this. I seem to remember an in-line connector somewhere that was common for corroding, causing bad Lambda readings, but I don't remember where it is off hand.

RE: Check Engien Light
 

Do you mean the connector around the throttle body area?

RE: Check Engien Light
 

Yeah, you've got the procedure about right:)

RE: Check Engien Light
 

Okei :)

Roto : Can you list up all the things I should Try befor buying a new Lamda?

That I would really appreciate !!
