Ford - Explorer :: 2002 - False Low Oil Pressure Light?
Jun 18, 2010
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 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 02 explorer XLT with the 4.6L and the oil pressure gauge has never worked (the three years I have owned it) I did an oil change yestarday and replaced the sending unit thinking that was the problem but the gauge is still not working. What other problem it may have? 4x4 light flashing (instrument panel looks like a xmas tree)...

Do any of you get a low tire pressure warning light even though all the tire pressure show as being fine?
Annoying that warning light comes on and it high lights tire pressure in yellow even though the tire it high lights actually has more psi than some of the other tires.

I have a 2002 ford explorer with 70000 miles on it. The problem is that the oil pressure occasionally go from normal to no pressure immediately. Then within a minute it pops right back to normal. It has happened when I first crank up and sometimes just going down the interstate at a normal speed. My fear is that the oil pressure is really gone and there is a pump problem but with it either working or not I fear it could be a sensor problem.

2002 W8 Wagon Automatic with 55,000 miles. Second instance of Check Engine Light (MIL) in three months. Nothing wrong, supposedly. Dealer writeup says: "MIL checked and found sporadic codes in 46, 15 module, cleared codes and road tested, checked ok."

I have a 2002 prius with 143,000 miles. On Friday, I went to start my car and put it in gear and the check engine light came on and the "triangle of death" lit up and car died. I turned it off and waited about 30 seconds and tried starting it again. It started and I drove 1/2mile home. Went into the garage and got the Actron/OBDII code reader. Pulled the code P3125 which when I googled it, it was referring to the inverter. I cleared the code and all was well.

I have been experiencing intermittent false activation of the ABS when I come to an almost complete stop. This allows the car to drift just a little further than desired. This started happening following a front brake job with a right caliper replacement as well. None of this caused the ABS light to come on. I did some net searches and followed recommendations to pull and clean the front sensors and reinstalled them. This resulted in the ABS light coming on. Oh goodie! So, I went to Advance Auto Parts and used their code reader and it showed the right sensor failure, so I bought a hub assembly to replace the sensor and cable.
It was only $20 more for the hub over the cable alone, so it was a no-brainer to me. I replaced the hub and no more light! Great! Upon the test drive, I was back to the slow speed false ABS activation. There goes $120 for nothin'! All of this is on dry pavement. Recently, after three months of the ABS thing, my 4WD HI & LO lights began to flash - 6 times each time and repeats regularly (every 3 minutes or so). My HI lock works, but I have yet to get the LO lock to engage (the auto lock has never worked on this vehicle since I had gotten it).

My factory gauge on the dash reads Zero. I have put on a mechanical external gauge and it reads normal.

So, last December, I was sitting at a stop light, when my engine suddenly started rattling. "Check Gauges" light on, ZERO oil Pressure..
Took car to mechanic, he removed the valve covers, and scoped out the timing chains with a camera, and found everything intack, and no chips out of the timing guides (125K miles on the engine). no sludge, nothing.
Engine runs fine (for 5 seconds at a time) no issues. Removed Intake to check the Oil Pump Drive Gear, all is well.
Removed Oil Pan Inspection Plate, All is well. ZERO plastic chips in the oil pan from timing guides, ZERO sludge, all is clean.
Back up to top of engine, pull the Oil Pump Drive Shaft using needle nose pliers from the top of the engine. BUT!!!
Only the top 8 inches of the Oil Pump Drive Shaft comes out! The bottom gear is not present! Is it still in the oil pump?
OK, so I need a new oil pump drive shaft. no Problem.. BUT: how do I get the broken oil shaft out of the engine before I put a new one in? Use a magnet? Rubber hose?

Got a recall letter last January from Toyota concerning a false warning light on my model. Letter mentioned that moisture in the cables was triggering a false warning message about the main battery. My 2002 was having this problem. The dealer refused to do the work. Told me they did that recall work in 2006 but I did not have the problem back then and Servco Hawaii told me that Toyota had not put that out as a recall back then. The light has gone off and on now for a year. Car drives perfect otherwise and only have 60,000 miles on it. What do I do?

I just replaced the trans in my 02 sport trac and have no speedometer and ABS light is on now. I made sure all connections on trans were tight and I didn't mess with speedometer sensor seeing how it is on the rear diff on this truck. spent two weekends replacing this thing and am not at all happy with the results. By the way i did it all on my back. No vehicle lift or trans lift.

2002 F150, 4.6 V8, 140k miles. Oil level good, oil was changed 2 months ago.
Driving along one day, out of the blue oil pressure light comes on, oil pressure gauge went to zero.
Engine did not run hot, no bad engines noises that I can hear.
Upon restart, oil pressure will be up on the gauge for minute or so, then goes to zero and oil light comes on.
Asked around, some say oil pump, some say oil filter or pickup tube.

I have a 2002 Explorer that had a whining rear, changed it out with a good rear out of my parts truck and now I have an ABS light on. It says something about input to the sensor and output from the sensor and left and right wheels. 4 Codes in all. I changed the speed sensor in the top of the rear to the one that was in this truck because the light wasn't on before and it still has this light.

I replaced my wheel bearings and wheels roughly 6 months ago, right after I noticed my wheels gittered when turning at low speeds. I assumed this was a power steering issue or the new tires. I have now learned from this forum that it is most likely stuck in 4x4 HIGH but has no indications on the dash. Just yesterday though the actual 4x4 High light started flashing in different variations. I get 6 flashes one time, then 8 flashes 2 minutes later on the dash and so on back and forth. When I stop I can put the truck in 4x4 high and the light stays on, same with 4x4 low. Then when I go back to 4x4 auto they go off but I still feel gittering while turning at low speeds. What would cause this? I see a lot of people replacing the Xfer case control module but no one seems to have the same problem.

My son has a 02 - 2 wheel driver xls. His over driver light is blinking on and off. what the problem might be? He has about an 80 mile round trip drive today before he can get it to the dealer. Would he be damaging the vehicle if he drives it that far?

02 limited explorer with 114k. The door ajar light keeps staying on and the dome light wont go off. This has happened 5 times now in 2 days. I open and close each door and hatch a couple times and it eventually goes away or I turn off vehicle and restart trying to clear message. How do I test and locate where the issue is coming from?

My 2002 explorer, 4.0l engine. My 4x4 light on the dash blinks 10 times and I've found that sometimes the 4 wheel drive locks in. When i pull into a parking space on dry road I can feel the front of the truck Jerking when trying to park. I hit the 4x4 auto button on the dash a couple of times and the 4 x 4 will disengage. While driving on dry road yesterday the 4x4 light started blinking and I felt the 4x4 slam in. The 4x4 light still blinks and I can't disengage the 4 x 4 this time. The truck has 140,000 miles on it. I'm thinking its the 4x4 control module but I'm not sure.
