Within 10 miles of leaving the oil change place, Mom's 17 Jeep Wrangler 3.6 L oil pressure light came on and so she took it back and they verified it had oil. Had the OP sensor replaced at a different shop and about 40 miles later, after it had been left idling for several minutes, the OP & CEL's came on again. OP was registering 4-10psi on the panel. Not leaking oil and 19k on the motor.

Replaced the OP sensor again, but the mechanic verified independently that the pump is only putting out 10 psi max when warm. Normal OP for the first start of the day.

Any ideas here before I take it to Jeep? Changing the Oil Pump is more than my shop wants to take on as I understand it's very labor intensive.

I don't believe in coincidences...they put in the wrong viscosity of oil, do another oil change.

Done. No change after 25 miles of driving.

Oil pressure more normal at acceleration RPM's. After it has driven 5-10 minutes OP will drop to 0 at idle, then back to the upper 20's, low 30's accelerating again.

Have you pulled the code?

I haven't. And I didn't ask.
