Oil pressure fluctuates

[mandop86]

I’ve noticed in other threads that some say it’s normal for the oil pressure to fluctuate but after today I got on the Yukon a lil bit for a slick water burnout and the gauge went all the way up and a red light flashed and I let go of the throttle. It’s been fluctuating very minimal since I bought it from dealer but has me thinking I should get a new oil pump or suggestions….thanks in advance.

Have you checked the pressure with a mechanical gauge yet? I'd go the cheapest easiest route 1st--try swapping out the oil pressure sensor, or if there's a screen under it, it might be clogged.
