High temp sensor after oil change to synthetic oil on 09 JGC 5.7 hemi
Just bought a 2009 JGC limited 5.7 hemi engine. After oil change to synthetic oil I'm getting a hightempsensor and o2 sensors. Anyone heard of that or coincidental?

Did the issue show up immediately after oil change or some time later? If immediately I would be wondering if the O2 sensor wiring was damaged during oil change.
Did you verify there is adequate oil level?
Where are you seeing these errors?

Old fart with a wrench
Did you do the change yourself or had some monkey with a wrench do it? I'm going with the damaged wiring.

High temp
Well....the 2009 is running. My husband took it to a place for oil change. He noticed the oil leaking, could this have caused a temporary glitch cuz it's fine now. Weird.

Thank you for replying. Yes, that is strange. Don't be surprised if fault codes come back. But I am not clear on the oil leak issue. Leaking before or after oil change? The more specific details provided the better the answers might be, either here or at a service place.
