Turned on this morning and getting a service suspension message to dash. When driving home got a low oil message to dash add oil. I am about 600 miles into oil and filter change using amsoil oil and filter. Pulled over and oil level normal on dipstick, no leaks from plug or filter. Nothing over heating. Only thing that is slightly off is pressure a little high on oil. Usually around 40 driving on highway today was about 55. While at idle it was 35/40. Any advice on where to start would be appreciated!

Need a scan of all 4 code families to see what the suspension system is reporting. A generic P code scan will not be enough. Code families are P, C, U and B.
Shop level scan is needed. Oil issue could just be a bad level sensor.
Without a full spectrum scan everything is just a guess. Scan is step one in any shop.

Thank you, I have it scheduled to go to my mechanic next week and have another truck to drive so I’m going to let it sit. I’m slightly paranoid our 6.0 Yukon had check engine light come on a year ago and ended up having valve/lifter issues and all kinds of stuff. I have to say I’m not overly impressed with either Yukon xl or suburban we own when it has come to maintenance issues. My 2003 ford truck has spent less time in the shop!

For anyone out there looking for info on this wanted to give recap of repair. It won’t help because a critter got inside and chewed about 5 spots in wiring harness. Makes sense seems how the ride height sensor went and next day low oil message flashed. Just wanted to give closer to this issue in case anyone comes across the list in future.
