Oil Pressure Problem

[kkernahan]

The Oil Pressure does not come up in cold weather at start up on my 2002 expl. It sometimes takes up to 2 min to register on the guage, and its fine with no fluctuations. I understand the sensor needs 5 psi to register. Is it the sensor?

Could be the cold alone. It is possible that it takes that long for the presure to build for the sensor to read it. It could also be the sending unit stuck in the cold.

Maybe your oil is too thick. Maybe something like 5w-30 or thinner might start the oil flowing faster on a cold New Jersey morning.

I only have 500 miles on the fresh Oil 5w-30 synthetic. It doesnt make any noise whil guage is low, so Im assuming its the sending unit stuck in the cold.
Thanks for the repies

I bet on the sender.

sounds like its the unit itself, not an actual deprivation of oil in the engine

this happend to me I fixed it by changing the oil sender just to make sure is was dead and dropped the oil pan and took the oil screen down and degreased the hell out of it cleaning it up and then put in some 10w30 mobil one synthetic it works now
