VE SS-V ls2 engine fault codes

[ls3 power]

I had a engine light. Took to down they told me it was a o2 sensor. Cleared. ( i was getting a service at the time). If comes back go down and they will check it again ( 80 bucks just for that)

4 days later, comes on again..2 months later i had the time to take it down again. Bank 1 . Replaced both o2 sensor on bank 1. They said the other side, bank 2, might go too... i happens.

2 days later engine light . this is where i am at.

Bill was o2 sensor bank one 500 for both ( plus the original 80 from before) both were in bad nick, they showed me.

They look easy to replace. are they?

Also i am looking on ebay for a engine fault reader/clearer. There seams to be alot under 80 bucks.

Can someone recommend one for a Commodore `10 VE SS-V.
Also o2 sensors around around 60 to 100 ( i asume i would need front and back), recommendations... As i asume it would be around 580 again in price for them to do it.

O2 sensors are dodgy things. Yes they are easy to replace. Mine went after I put a new exhaust on and had a tune.
Swapped them in the driveway. 10 minutes for both.

with the 02 sensors there is a big difference in price of 40 to 100. Is this a more is better option.
