Erratic oil pressure reading-2025 Ranger 2.3 eco boost

[Jason B]

Hello everyone, a new member here,

I had read some posting about oil pressure gage reading, on ford ranger, so it seems this might be common problem.

I have 2025 ford ranger XLT, 4x4 with 2.3 eco boost engine with 4600 miles on odometer, that has erratic oil pressure reading.

At stop light in city shows about 25 to 30 PSI, when traffic starts rolling, some time the pressure goes up to 95 PSI, and on another lime might goes down to 22, 23 Psi or graph does not move at all. Cold temp engine, or normal operating temp does not makes any difference.

On freeway ramps, sometime, pressure stays around 35 PSI all the way to 70 miles and sometimes goes up to 95 PSI then settles back around 45 to 55 PSI, which I think is normal range.

I have taken the car to dealer, but I do not think they test drive it and just telling me pressure is normal, which does not make sense to me. Am thinking about taking to another dealer for second opinion. I was told this new truck has variable pressure oil pump, which I am not familiar with, could that have anything to do with reading.

Has anyone else experienced the same problem and what did you do to resolve the issue.

Any feedback is greatly appreciated.

Varying oil pressure is normal operation, on any modern vehicle.
It's controlled by the ECU.
It's how the cam phasers work to vary valve timing.

It's normal, just be glad you get a real gauge readout and not a dummy gauge that just sits in the middle until all your pressure is gone. The service manual gives a wide range of expected oil pressure even at idle.

Thank you for feedback. I understand the variable oil pressure. under different condition. However, driving steady 45 mile and hour in street traffic, 1600 rpm with no sudden fluctuation in speed, should not cause oil pressure jump from steady 35 psi to 95 psi for no reason at all. Any way again thank you for your respond.

Wow 95 psi. I haven't seen mine go that high.

Thank you everyone for feedback. After a visit to another dealer, apparently software update was needed and installed, and it seems that problem is solve now.
