I have a 2007 Grand Cherokee with 5.7 Hemi
just over 100k miles on it. We live in the mountains and this is my wifes daily driver so I would like to get it fixed for her comfort.

I had the P0298 code a while back which calls out engine oil over temp. It seems to come on while going down the mountain under no load. I replaced the sensor and it has been off for a while, but it just came back on.

More recently I have been getting a P013c code. Best I can tell is that it's some sort of an O2 sensor code?

Any help with these codes would be great!

Thank you!
