Change an oil sending unit?

It depends on how hard the sending unit is to get at/location. My database doesn't have labor time info for that part. If it is easy to get at, you take the electrical connector loose, screw out the old sending unit, screw in the new one, reconnect. This is just generic info, I do realize you wanted more than that.

Can I ask why you are asking?

Hey WARREN1814,

It sounds more like a problem with the oil filter or a restriction in the oil pickup in the oil pan.

When was the last oil and filter change?

If you would like to replace the oil pressure sender I have attached a picture showing the location.

Once you have ruled out the oil, filter and pressure sender I would advise carrying out a pressure check at the pressure sender port from cold and seeing what you have there.

If the pressure is actually low then the next stage may be to remove the oil pan and check the pickup strainer.

If the pressure is actually ok then you will need to pinpoint the electrical fault.

Hey WARREN1814,

Below are the instructions for removing the oil pan for you to check out.

It is a fairly involved job on these vehicles.

There fore you will want to rule out all other options before removing the pan to check.

Hey WARREN1814,

Any restriction in the oil delivery system will be harder for the oil to pass when the oil is thicker at low temperatures. Hence the slow build up of pressure.

Driving with low oil pressure will cause premature wear to internal engine components.

It is vital to ensure you have the correct oil pressure at all times when the engine is running.

I would at least get the engine oil and filter changed as soon as you can.

Let us know how this goes.

Hey WARREN1814,

No problem at all. Please do keep us updated if this cures your oil pressure issue.

Thank you for using 2CarPros!

Any further vehicle related questions please don't hesitate to ask.

Hey WARREN1814,

I would say that's a great idea.

Was it just after the oil change that the gauge responded this way.
What I mean by this was had you just changed the oil and filter and this was the first start attempt after the change?

If so it takes a couple of seconds for the new filter to bleed and the pressure to build.

If it now builds pressure straight after you start it I would say it is okay.

If you are still getting variable readings from the oil pressure gauge I would say replacing the switch is a good idea.

Before removing the oil pan and getting more involved I would say attaching an oil pressure gauge and getting an actual reading of the oil pressure from cold would rule would mean you can pinpoint the issue to the oil pressure system itself or the sensor/gauge system.

Let us know how you go after the replacement switch.

Regards, Joe

Hey WARREN1814,

Did you replace the pressure sensor?

It would be great to rule out a sensor issue.

Please do let us know how you go here.

The filter should stop the oil draining back into the oil pan so when you start the vehicle pressure should build very quickly. A replacement filter should have sorted this issue if the other filter was allowing the oil to drain down.

I think it would be a great idea to get a pressure gauge on it from cold to see what is really going on. If you really do have low pressure then driving it like this may do engine damage.

Regards, Joe

It could be the gauge that is having an issue, but we need to get a manual reading to be sure. I am leaning toward what Joe said that the oil pump screen is clogged and reacts differently in different scenarios. Try the sensor as well and let us know please.

Please let us know what you find. We are interested to see what it is.

Thanks for the update! You stay safe as well.

Hello, I'm Danny.

Before you replace the MAF sensor the code also refers to a restriction in the PCV system, or a blockage in the air filter housing or air intake system. You might want to inspect this first. I've attached the code info picture below. Hope this helps and thanks again for using 2CarPros.
