Yeah I already searched that and other previous posts I could find gas cap didn't help. Was hoping someone may have faced a similar problem. Trying to not have to replace ECM unless no other alternative.

I have this code as well (p1039) after installing a new o2 sens. How did you know it was a short and how did you fix it?

Turns out in my case I bought a faulty sensor! Got a stock one and all is well. My expertease ends though as to how I should have tested the sensor.
