I've been noticing recently that my oil pressure gauge has been hanging on "0" until I drive it for awhile, then it will go up to a normal level of around 180-200. It used to register the pressure quicker. The oil level is fine. In fact, I just had my 5K (at 6K) service a month ago.Again I ask, is this normal?
View 2 RepliesThe oil pressure gauge in my 04 v8 treg doesn't move until I drive it for about 15 minutes. Is this normal?? When THE BEAST is idling it takes about 15 minutes to pass 60 on the oil pressure gauge. I find this very odd.
View 3 RepliesWhen I start my TReg on a cold start it takes my oil pressure gauge about 10 to 15 minutes to even move up a little bit. My engine also has a loud clatter for about 1 minute when I start on a cold start. Is this normal, could I have a faulty gauge?
View 12 Replies'97 F150 4.6L 4wd automatic... My gauge jumps around, sometimes it works and other times it shows no pressure. Could that be the oil pump? Or is the gauge most likely bad? Whats the actual purpose of an oil sending unit?
View 6 RepliesLast week I was driving on the highway and noticed the oil pressure gauge showed no pressure. Limped a half mile to the mother-in-laws and called for a tow. As my truck was pulled onto the flatbed I could see oil all over the bottom of the engine, tranny, rear end, etc. Turned out to be a bad oil pressure sender, which was leaking enough oil to blow the plug off the top of it.
I replaced the sensor, cleaned the engine and under-carriage, checked oil level (which showed no loss of oil) and drove around for a week without an oil pressure gauge while I waited for a new pigtail. Put the pigtail in yesterday and drove it today for the first time since. Gauge was working, got to the bank and it was reading zero pressure again. Limped home and watched the gauge go back up quickly and then back down. This happened twice and was showing pressure when I shut it off. Checked under hood, no oil leaks and plug is still secure.
The tire pressure warning light has been on in my car for about a week. The dashboard computer says that the tire pressure in the front right tire is 17 psi, but when I use the pressure gauge, the reading is almost 40 psi. Is this something I should be concerned about? What could be causing this problem?
View 16 RepliesWhat would make the oil pressure gauge fluctuate and go to zero? I already replaced the oil sending unit, and changed the oil and filter, whats left? maybe a bad gauge?
View 5 RepliesSo I have an 88 k1500 with the 350 that the previous owner removed and rebuilt... Didn't hook a lot of stuff back up etc... It's like a puzzle. It runs good for the most part but the oil pressure gauge in the cab pegs out when it's running. I've heard 1989 and older 350 engines have 2 oil pressure switches/sending units. I know about the one up by the distributor. But can't seem to locate the other one. Also what does the one by the distributor control? And what does the other one control?

View 14 RepliesI have a 1991 Mazda Miata. Recently I noticed the oil pressure gauge was vacillating wildly between 30 and 60, whereas it always stayed at 30 before. I checked the oil -- it was fine. I took it to my nearby mechanic who said it was the oil pressure gauge. He replaced it with a Miata part. Now the oil pressure stays at 60 once I'm over 20 mph. So what is the correct oil pressure setting and do I need to take it back to the mechanic?

View 5 RepliesWe have a 99 Suburban LT 5.7 V8 4x4 with 210K miles. My wife was driving the vehicle the other day and while at a stop light the oil pressure got very low approximately 20psi according to the gauge. I need to find the oil pressure sensor location to check the true pressure using a pressure gauge but I can't seem to find it. From what I've read it should be by the oil filter or by the distributor cap or on the underside of the engine. It's neither around the oil filter or the distributor (using a mirror looking everywhere) nor on the underside of the engine.
What I have found is two sensors. A sensor I believe by #1 and #3 spark plug (driver's side) screwed into the block and a sensor on the passenger side of the engine (screwed into the block) accessed from underneath the vehicle. The sensor on the driver's side of the vehicle appears to be the best candidate however neither of the sensors looks like the replacement part when I view the picture of the sensor online.
My factory gauge on the dash reads Zero. I have put on a mechanical external gauge and it reads normal.
View 2 RepliesAfter having my oil changed at a local place, the oil pressure gauge showed "high." hoping it would go away, i drove for a week. it didn't... took it back to the shop and they said it was a little full which would cause it to show high pressure. That was earlier today. The gauge however has not changed. Still shows high oil pressure. I need to drive 400 miles tomorrow and am not sure if it is safe? Perhaps just a bad sensor??? I need to know if i can hit the road or not.
View 5 RepliesMy oil pressure gauge jumps all over the place when I get over 3000 rpms. At lower rpms it is in the normal range and the engine sounds ok. How can I tell if this is the oil pump or the sending unit or the gauge? This is a 1980 CJ5 with a 151ci 4 cylinder.
View 2 RepliesI had the oil changed recently in my 2008 tundra 5.7 v-8. I noticed the oil pressure gauge moving. When I started the truck, I noticed the gauge will move to the right of the indicator in the middle of the gauge and then it will go back to the middle mark on the gauge when it is warmed up. I also notice that it moves a little when I accelerate. Maybe it has done this in the past and I just have not noticed but was wondering if I should be concerned.

View 4 RepliesI changed the sending unit and replace the oil filter with a motorcraft unit and still can't get the oil gauge to read pressure. Since it is a gear oil pump I don't believe it is the pump.
View 2 RepliesI have an 01 F150 Lariat Supercrew 4x4 with the 5.4 Triton. The truck has 222,000 miles on it. Recently, I have noticed that when I am stopped at a stop light/stop sign while in gear, the oil pressure gauge drops to zero and the light comes on. As soon as I let off the brake and give it gas, it pops back up to normal. While driving, the needle never moves and stays consistent until I stop again, and back down to zero it goes.
If I put the truck in Park, the pressure goes back to normal. Same with neutral. It seems it is hit or miss and does not do this all the time, but I just wanted to see what your thoughts are. After doing some research I am leaning towards an oil pressure sensor/sending unit.... The truck runs perfectly fine, I just want to make sure it is not something more serious.
My daughter has a 94 XLT with 4 liter OHV. This the first time I have noticed a vehicle to have both an oil light and a pressure gauge. Periodically the check oil light will come on, but the gauge shows very good pressure. The oil level is full. I'm not sure what to make of this. I know the engine was replaced with a rebuild but no idea how many miles are on it now. Oil looks fairly clean tho it is due for an oil change I think.
