Check PowerTrain warning

[neilsv6]

Hi Guys
I own a vz sv6 04 manual and the powertrain warning system on my dash that keeps poping up it has gone away previously after a few weeks and has recently come back on.
What are some common problems that could cause this and is it an easy fix???

Hey mate.


I had this problem twice in the last 2 months.

I ended up replacing all 4 oxy sensors on the exhaust. Problem hasn't come back since.
