Hey Gang,

I noticed after few minutes of running my car, the check Engine light and TRAC Control light comes on. I have heard that its O2 sensor problem. Anyone know which O2 sensor it is. Primary or secondary?


Thanks

 

After few weeks waiting for an answer on my check engine light and TRAC light. I took my car to my friend's shop and ran the OBDI. The problem with Knock Sensor problem causing the check engine light and TRaction control lights to come on.
