Ok, I know what this is, but my question is I Put a new motor in this truck back in July. 3 weeks ago It started making a ticking clanking sound, at idle while at operating temp. Engine being under full warranty it was replaced. I had no trouble codes before it went in to the shop, it ran and drove fine, it was loosing oil pressure at the top end of the motor. I picked it up today and after the new engine was installed and headed out and my check engine light can on. Prompting me with the O2 sensor. It wasn't on during the time after the engine was installed and their test drive and driving it. It came on after I picked it up. I am kind of irritated because it wasn't on before and now it throws it. Could it be from the install of the new engine?
have the same problem?
