Is a high oil pressure reading more likely to be the sending unit or stepper motor?

Default Is a high oil pressure reading more likely to be the sending unit or stepper motor?

'02 Tahoe

At idle the gauge shows 60psi, and with any amount of acceleration it hits 80. Obviously the readings are inaccurate and I want to fix it in case I ever need to know the real oil pressure. I thought I'd ask before throwing an unnecessary part at it if the sending unit or gauge or something else is most likely responsible.

Thanks for any help.

Sensors are the most common thing to fail. Use a GM part and not aftermarket stuff as aftermarket sensors are not reliable.

Suggest you consider getting a reliable pressure gauge and connect it in place of the sending unit.
At least you will know what the actual readings are and go from there.

Transducer is more than likely at fault. I had the exact thing last year.
