Check engine light in ve

[SV346]

hey fellas i was just curious as to why my check engine light has come on, because i got a twin3" exhaust put on yesterday and the bloke said the light would probably come on, but does anyone know exactly why? is it just a matter of getting it cleared and i can go on my way or do i need to maybe replace the o2 sensors? Are the o2 sensors still a minor problem in the ve's as in the vz's with exhausts? Any responses are much appreciated! :) Hell i love twin 3"s with big pacies :p
Is there any way i may be able to clear the light myself? Its quite painful whenever it comes on

I think as more air flows through your system, the O2 sensors crap themselves and send the warning off. Thats the simple explanation. Any experts would probably know the correct terminology to use. It happened to mine twice and was an easy fix. Took about 2 minutes.
I find that if youve had some work done by one of the sponsors on here that they would look after you and kindly fix the problem for you. I dont think that Holdens would do it or recommend doing it. I dont think Holdens recommend doing much really.

No you wouldnt be able to do it yourself, unless youre a tuner or have Tech 2.

so all i need to do is replace the o2's and get te light cleared? or will a sledgehammer work better? :)

There are many threads regarding the "Check engine light ". Just type it in the search section.


PS. Also check your spark pug leads. The rear left hand side ( as you are looking at the engine) sometimes come loose.

You will still need to get the warning sign cleared though (scan gauge, tech 2 etc.......Cheers John

thank you ill be able to sleep a bit better 2nite now

The O2 sensors are probably ok. It might only be one of them doing it. A tuner will be able to tell you which one it is and fix it.

Errors need to be cleared by a tuner.

or anyone with a tech 2

I have been told that a Tech2 can't clear all the errors and the only way to guaruntee the engine erros are cleared is the flash the PCM.

so holden cant clear a code on there own cars
very strange
from what i have been told holden can flash a new tune in

Well i managed to find out why and get the engine light cleared at lunchtime only to have it come on again this avo :soap: !!! Apparently it will continue to throw codes about the o2's untill i get it tuned to say its right, so im looking into getting it tuned and a cai in for good measure also :)

Easy fixed and par for the mods you have done. That engine responds great to extractors the exhaust ports need all the help they can get to keep up with great inlet ports.

You shouldn't need to pay for a whole tune to get it done if you are not ready for one yet. A tuner can easily change the settings so it doesn't throw that code. I am however not sure whether that incurs a licence fee as a different ECM to any he has tuned previously. If so, it may cost you whatever the licence fee is for the software he uses ($100?? $200??) but that is included in the cost of a tune so when you get the tune done the cost should be reduced by that amount. Oztrack should be able to tell you for sure.

If it doesn't incur a licence fee a tuner should do it for you very cheaply, maybe even for free in the hope that you will therefore return when you need the tune.

Don't waste your time with a CAI!! Bang for your buck go straight for an OTR!

I love it when someone posts a "use the search button" response then continues to answer the question... :rofl:

I completely agree!!! I also don't understand what the big deal is about something being asked that's been asked before. So what?

My girlfriend asks me how my day was almost every day but I don't say "please refer to previous discussions on the same subject".

The problem can be that when someone who does actually conduct a search gets a result, they have to go through X amount of unnecessary threads to find the answer. :idea:

If people search first and post in similar old threads, it makes it easier for the entire community later on.

If they don't then people who aren't aware of the search facility and how valuable it can be will just keep on asking the same old questions that have already been asked and answered many times before. All that does is result in more and more redundant clutter which only makes it harder for people who do do the right thing and search first. :(

Yeah, what Macca said!! :D

Sorry to bring up an old thread, especially since it is one that has been covered before but this is the most recent so thought I would put my question in here.

Anyway

Just got HSV extractors and 2.5 inch CAT Back put on my VE SS M6. For some reason I thought that because these were HSV headers that it wouldn't throw out the check engine light but it did. Does this sound right or do i potentially have a real issue?

The other thing that has happened is that I get an alarm saying the stability control is off and I can't turn it on. I can't see how changing the exhaust could impact the ESP. Any body got any ideas?

[BadSeed]

i found my esp issue was caused by the brake sensitivity being set too high.. i had to have it reset or whatnot and that esp thing went away..
im looking at throwing on extractors and 3" cats tomorrow hopefully... hoping i dont get a CEL (check engine light). One of the other members on here. deanssv put some on his car and hasnt had a CEL yet. maybe its because the xforce cats retain the same factory position. ?

HSV extractors definitely shouldn't set the check engine light on if everything is OK. I had them on before going to Pacies.

ESP is extremely sensitive to many factors. I had mine come on one day driving along in lightish rain and in the end we decided it was because my (then) pod filter had got damp. (I started a thread on here about it as I was puzzled/concerned). Two hours later the car was restarted and was fine - hasn't come up again unexpectedly.

Thanks guys I will reset it over night and see what happens. If it comes back, I will start by taking it back to the exhaust guy to check everything is ok.

Wonky, thanks for your info about esp. Hopefully the problem relates to whatever is causing the check engine light.

Will let u know how i go.

Okay msytery solved, the wiring to the MAF sensor had fallen off.
I put it back on and both the check engine and ESP light went away.

It would seem the MAF some how relates to the ESP. This would explain why it came on when Wonky's pod got wet.
