Re: High Oil Pressure Reading - Sending Unit?
That happened to me one time in my Ram and my bud said check the filter
because the sending unit checked out.
I pulled the filter and cut it apart and found that the paper, yes paper
filter material had collapsed. I will never use FRAM filters again, not
even their high end ones. I guess any filter can fail.

Re: High Oil Pressure Reading - Sending Unit?
I wouldn't worry if this is a single event kind of problem. It sounds like
the pressure went up because the oil was thick due to the cold. If the
pressure remains high when the weather warms, then start to look for causes.
You did not say what the temps were outside, but if they were so low as to
drive the oil pressure up, then I woulud suggest switching to 5w30 or 0w30
for winter, then back to 10w30 or 10w40 for summer.

Re: High Oil Pressure Reading - Sending Unit?
Hi Tirya,
I'm betting you have a short in the wire leading to your oil
sending unit. I've never heard of the unit failing, and reading high.
