Ford Ranger / B-Series :: 2002 V6 - Low Oil Pressure / False Reading On Gauge?
Jul 16, 2013
I have a 2002 Ranger V6 3000 with 100K miles. Can I add a higher viscosity oil since my pressure gauge is acting up. I changed the sending switch twice but the gauge still acts up occasionally. I was thinking of adding 10/ 30 on my next oil change. I do live in the area where the air temp is quite high in the summer. The truck runs well except for the oil gauge, in my opinion, is giving false readings.

I have a 2001 Ranger 4.0, 4x4 that just hit 100k and the oil pressure gauge doesn't show a reading for about 1 minute after startup. Also, the check gauge light comes on. What do I replace to fix this and is it something I can do myself? I am mildly handy. Would you worry about fixing it or just let it go because it's obviously getting oil pressure.

1991 Ranger STX, 4.0. Had a leak from the rubber seal on the thermostat. Changed the thermostat (stat 195) and seal. Now my temperature gauge is not showing a constant reading, goes to half way and when the thermo opens the gauge falls down to a quarter. The gauge is cycling this way every time the thermo opens.

When I fill my gas tank (in other words, until the pump clicks off on its own) the dashboard gas tank gauge is at only at about 3/4 full. Itdoesn't seem to be the type of needle that shleps its way up after a few minutes. So I continue filling on my own until I have as close to a full tank as I can get without any overspill. What's up with that?

i own a 67 old cutlass supreme and the fuel gauge, as you turn off the car goes down to 3/4 of a tank, when you start it up it goes to full. But the car is really empty! That is the only reading I get, no matter how much gas I have. I replaced the sending unit and I cleaned the ground wire, it still does the same.

I have a 97 Splash with the 3.0, oil pressure goes up to about the middle of the gauge after startup, however, it stays there whatever I do, warm/cold, idle/5500 rpm. Is it supposed to be like that?

My oil pressure gauge does not work. I was told that it's most likely the sensor. Where would I find this to change it out?

I have an 87 Ranger and the oil pressure gauge is slow to respond changes in pressure. Is this the way the gauge is designed to work or do I have a bad sending unit?

I am working on my friend's '02 Explorer 4x4 with 4.6L engine with 122k on it, the dash is telling him that he has low oil pressure. When it first came on he was an hour away from home, what he told me he did was pull over and checked his oil level right away. He found that it was still full and since the engine wasn't making noises he resumed his trip home. During the drive home he said the dummy oil pressure gauge would read normal then drop all of a sudden then come back up again after so long.
When he got back home he changed the sending unit plus the oil and filter and his Explorer still reads as if it has no oil pressure. The needle does not read anymore, he noted to me when he pulled the filter off it looked like it did not have the normal amount of oil inside it. I did not get to see it so I can not verify that. When he starts it it kind of sounds like it has to fill the filter every time like a fresh oil change, rattles around for a second then smooths out and sounds good..
So is his oil pump to blame for the light being on or is there something wrong with the gauge in the cluster? I have not hooked a mechanical gauge up to where the sending unit threads into so I don't know how much pressure it actually has. If not the oil pump what could be the cause? My other friend and I looked at the oil that came out of the new filter and we thought we saw metal specs in the oil. Is it new engine city time? It has such low miles to need an engine.

I have a 2002 Ranger with a 3.0/auto with about 180K on it. It runs good but for the past 6 months I have had a problem starting it. It does the same thing hot or cold but is a LITTLE easier when cold. It is very hard to start, you have to grind the started for about 30 seconds then it starts right up.
I checked to see if I could hear the fuel pump when the power is turned on and yes I can. But after checking the fuel pressure, there is no fuel pressure with the power on and the engine not running. Once the engine starts, there is about 65-68 pounds of fuel pressure - and the truck runs just fine. Starting is the only problem.
I was told I had to replace the fuel pump. Is the electric pump in the tank the ONLY fuel pump on the truck, or does it have a combination of the electric/tank pump and a mechanical pump on the engine?

These are my gauge readings at 70 degrees Fahrenheit. According to an AC conversion for gauges calibrated in Pascals, 35-40F converts to 241-276 KPa, 140-160F converts to 1000-1103Kpa. The gauges are in Mpa which by conversion is 3 decimal points to the left so .241-.276 and 1-1.103 Mpa. Here are my gauge readings at 68 degrees ambient temp. Rear air is same as an ambient temp on max ac and the front is pictured. There seem to be virtually no pressure differences which I would interpret as a novice that there is ) freon flow.
There is freon in the system with the high pressure being approx correct but the low side is too high if I understand correctly. Basically when at highway speeds at 75 degrees yesterday the front AC was cold and the rear was outside vent temp only. There are slight leaks in the low and high-pressure valves. I have a Mastercool replacement tool but they did not send a fitting for the high-pressure valve. What these readings mean as far as what may be wrong?

I have been having an intermittent (2 times in the past 2000 miles) oil pressure gauge not reading. As I own a 6.0L I understand that this is just a pressure switch in reality and if the engine was starved of oil the HPOP system would kill the engine. The first time the oil gauge went out it was raining out. The second time was after going through a carwash and getting the underbody wash. At this time my battery light also came on for a few seconds.
Both problems seemed to go away after an engine restart. Today it is snowing lightly and my battery light came on again. I happened to be monitoring the battery voltage and FICM voltage via OBD II using Torque app. At no time while the battery light was on today did the battery voltage drop below 13.5V. The FICM was also stable at 48.5+/-.5V.
As the battery voltage read by the PCM is not actually dropping and the previous oil pressure gauge and the fact that my left blinker indicator is out I am thinking I may have electrical issues with the gauge cluster. I have never had these issues while driving in dry weather. Where do I start troubleshooting this? Also I am going out of town for the next two weeks and my girlfriend was going to use the vehicle. Is it OK for her to drive?

Just changed the fuel filter in my '04 6.0, no issues worked just like normal, filter primed truck started, great. Well now my fuel pressure gauge is reading dead 0, I know that can't be right because the truck is running, but noticed my fuel mileage seems about 2 mpg lower all of a sudden. Had R&R Injectors installed about 40k ago, figure it's just a bad gauge but wanted to check and see before messing with the frickin wiring. Also, have had a lot of pressure buildup in the coolant tank, has had head gaskets and studs, anything else it could be besides head gaskets? Have had a lot of wiring issues with this truck from the previous owner....

Can I read oil pressure on my scan gauge II ? If so, how do I do it?

I just tried doing the self test for reading the codes via the check engine light with the OBD1 system on my '93 4.0 Ranger. Problem is: When trying to mark down the flashes of the check engine light, they flash so erratically and rapidly that there is no way to accurately count. At times the light flickers so fast it never even gets to get fully bright enough to tell if it is actually a "flash" or not. I'm (again) trying to diagnose an issue with the truck starting and running fine for about 3-4 minutes and then like flipping a switch begins blubbering and belching out black smoke, check engine light flashes on/off randomly, then the engine will eventually die. It will restart provided the ignition switch is turned all the way off and attempted again, generating same results only within 30 seconds or so. If you try restarting w/o turning the ignition all the way off, it'll spin over but won't start. ECM?

I have an 02 f350 7.3 power stroke...Yesterday I noticed the outside temp was reading wrong,it was jumping from 67 to 86 to 92 back to 67..Temp was prob around 90 with high humidity and my a/c was on..So I got to where I was going and when I restarted my truck to go home the fuel gauge dropped to empty(I just fueled the day before) and fuel light came on and outside temp still wrong on the overhead digital display...Are these two things related???
Stopped the truck restarted it and fuel reads correctly again....Went out today and fuel light back on and on empty...Outside temp wrong again,a/c is on .....I disconnected the batteries when I got home to "reset the system"if there is such thing, fuel gauge working but outside temp wrong..?? Where is the outside temp sensor ?could condensation be running onto the sensor and throwing off my temp gauge? Just strange that both these things happened at the same time......I don't think its a fuse or they wouldn't work at all. I should mention all the other gauges work correctly...

Twice in the last year my 1999 Ranger (@138,000 miles) has started running very loudly: I checked dash and see oil pressure gauge says no oil pressure. First time this happened, I pulled over, had it towed. At garage they start it up: gauge normal, they check oil says its OK. I take it to the dealership, they replace sending unit, but can't explain why it was running loudly. Today same thing happens: I checked oil pressure gauge, it's OK. After an hour, starts running loudly, gauge in red. Park car for 15 - 20 minutes, start it up: all is well: gauge OK, running quietly. This is amy 'spare' car, so it only gets driven 1 -2 times per month, short distances.

Gas gauge went from about 1/4 to full in about 3 seconds and hasn't moved since. 2000 B3000 Mazda 3.0 V-6 auto. I've checked all the instrument cluster fuses (11,26,33). I know of the method of disconnecting the connector at the gas tank to see if its the sending unit or the gauge but I can't see or feel in there good enough to do that. Would either one go bad that quickly? Doesn't seem likely to me.
I've read about a "slosh sensor" in a post on this forum - does my truck even have that? I've had an intermittent wiper problem a couple of times but the multifunction switch wouldn't be involved would it? I'm just trying to see if there might be a simple fix before I add it to my repair list when I take it to have the ball joints replaced.

I have a 94 Ford Ranger, 2WD, 5-Speed, with 2.3 engine. My temp gauge hardly moves at all... It actually appears as if it doesn't move it you don't pay close attention and were to just glance at it. I'm thinking it is most likely the temp sensor that is on the engine block as I understand there is also one that is in the line that controls the fans for the radiator. Am I approaching this in the right direction or is there something else I might need to do?

I have a 2011 xlt extended cab with a 2.3l 4 cylinder. The truck is great... I put 120,000 miles on it in under a year.
But about a month ago the temperature gauge started malfunctioning. for what ever reason -- the truck is NOT over heating-- the gauge would increase past the "H" and then the temperature light would come on. Because the truck thinks it's overheating -- the engine goes into a "safe mode" and runs with no power. When i shut the motor off and turn it back on temperature gauge resets and the truck will run fine.
Then in another 50 or 100 miles it will do it again. Why is it doing this? I took it to the dealer here in Columbus, Ohio and the mechanic installed a new thermostat and a new "control modulator" (and a part -- not really sure what it is called) anyway, the truck is doing the same thing and the mechanic still does not know

I just picked up a 1984 ford ranger long box 2 wheel drive w/ 2.0 l and carburetor for our daughter whom is just 15. it has a whopping 19,000 actual on it! It was my wife's grandma's farm truck - ordered it new from dear born. Any way, fuel gauge is pegged at empty and they had a new float assy put in about 5 years ago, but it is dead now, it doesn't appear that this sender is avail any longer. What part might fit in there and or what do i have to do to maintain the original gauge in the cluster but have a working sender to talk to it? is there another unit that goes in the tank that i can modify the signal out to read right with the built in gauge? There can't be too many different ones out there is there?
