ls1 engine light

[madsav]

Been noticing for the past 2 weeks on a cold start up the vt ss throws up the engime light, turn the key off then back on and no light everythings fine.
And now lastnight driving home i went over afew bumps in the road and now the light is on and staying on. the car still has all its performance doesnt seem to be lacking . idel`s fine. just not sure what else to look at while im waiting for my scanner to show up.
I did try swaping over my TPS and no diffrence the light stays there after start up

Only thought i had was the o2 sensors

possibly o2 sensors, thats what mine was anyway when i first got it

[madsav]

Would it be better to just replace them or get a tune done

Take both batt terminals off,meantime check all your sensor connections.after re-connection,if same read code.

it's more than likely either the o2 sensors playing up, or the oil pressure sender...mine did exactly what you described and it turned out to be the oil pressure sender. Cost about $70 for a non genuine one or up to $150-200 genuine from a dealer plus install/code clearing

There is a trick in getting codes from ls1. Once you get cable I will tell you or see my post.

i just got Autel MaxiDiag US703 ODBII/EOBD (Vehicle) Diagnostic Code Tool (Australia) | eBay with the help and advice from DLFHUB666 that should do the trick

Let us know how it goes because most of these types of scan tools won't read codes on an LS1.

Good to know. I bought a similar type of scan tool quite a few years ago and it reads live data but not codes.
OBD II 2 CAN Car Trouble Code Reader Scanner Tool DTC | eBay. I paid a fair bit more at the time.

Yes, It can be tricky buying scan tools but soop had a us703 an said it worked so i got one.The us703 is also very easy to use, never having owned one.
