My oil light goes on intermittently. When I start up, it's
okay.
After
driving around for about 15 minutes, it comes on, sometimes
steady,
sometimes it flickers on and off. It was on while I was at a
stop
light, so I turned the engine off and back on, and the light
went
off.
I did the same thing in my driveway when I got home and the
same
thing
happened, it went out when I restarted the engine. I have it
idleing
in my driveway and the light is staying off.
Do you have enough oil? What viscosity? What brand of filter
was
used?
At 225000 miles, you should be using 10W30 or 10W40
sd
I would like to replace the oil pressure switch, but i'm not
sure
which one it is. Chilton's manual doesn't show a picture. I
think
it's
right above the timing marks, with only one wire going to it.
If
that's it, does someone know an easy way to get it out? Chilton
overlooks the difficulty of its location.
I just changed the oil. It's 10W30, with a new filter.
I am not aware of any tricks to remove the oil pressure switch.
Just
unplug
the wire and reach down there with the appropriate tool.

I finally figured out what I had to do the get the oil pressure
switch
out. I can get a deep socket wrench on it after I remove the
alternator belt and unplug the switch. The problem I am having now
is
I can figure out how to disconnect the plug. There is no obvious
way,
and I am guessing Toyota has some special tool to press all the
detents so the plug comes free.
I'm afraid I am going to break the connector trying to get it off.
Can
someone tell me what the trick is? (I already broke one connector
trying to figure it our, and now the detents don't hold it on any
longer.)
If you already have the replacement switch, look at the connector.
There
should be a tab that is perpendicular to the connector body. On the
wire
harness side, there is a U-shaped locking connector that fits over
the
tab
on the switch. Use an awl, very small screwdriver, or pick to
gently
lift
the locking connector while pulling the harness off. Do not tug on
any
of
the wires, pull by holding the connector body itself.

Thanks for your help, Ray. I put a sliver of metal (cut from a razor
blade) in where I thought the catch is, but I couldn't get it to
work.
I may have to turn this over to the dealer repair shop just to get
the
plug off, and have them do the switch replacement. This switch is
just
in a place where I can't get to it or see it very well, so, without a
proper tool, I think I am going to break the plug. I don't want to
end
up with a badly seated or loose connector when I'm done.
Look at another electrical connector under the hood, like for the
coolant
temperature switch, EGR position sensor, etc. The connectors under the
hood
all pretty much work the same way.

Success! I have removed the connector without damage. I fabricated
three shims to insert under the detents of the connector and was able
to remove it.
Now I see that the oil switch required something other than a hex
socket to remove. (The replacement witch that I bought uses a 7/8"
deep socket. It looks nearly circular, like another special tool is
required to remove it. I'll have to make a trip to the hardware stor
to see if there is some tool I can use for this.
I won't be surprised if the OEM switch has a left hand thread!
After having goone through all of that, I found a tool tha probably
does what I need, WITHOUT removing the plug first!
www.redhillsupply.com/AST7801.htmshows a tool kit for this sort of
thing. I don't know if it works for a Camry. I wonder where I can get
one fast?
Auto parts store probably sell the correct socket, Sears hardware probably
also has it. BTW, you need to seal the threads with lock-tite.

Finally, I removed the old switch with a 1-1/16" socket.
Unfortuneately, the new one didn't solve the intermittent light, so I
must have a pressure problem, after all.
I was listening to the engine in the garage when the light was going
on and off, and I could hear a slight raspy sound when the light was
on. I wonder if that's the oil pump, or something is not getting its
oil. The dip stick shows full.
