Ford Ranger / B-Series :: 1998 - CEL On / Pending Code P0446
Nov 25, 2016
Today my Check Engine Light came on for the first time in years on my 1998 Ford Ranger. It has 363,000 miles on it. But the engine was changed about 150,000 miles ago. It's a 2.5 automatic. It runs good and has no problems until today. I was leaving a shop and when I started up the truck the Check Engine Light came on. It wasn't idling bad but when I went to take off it wouldn't hardly move. I wasn't even able to keep driving. So I stopped and turned it off and restarted it. Then the Check Engine Light was gone and it ran fine. I scanned it when I got home and it a Pending code of P0446.
I've never gotten this one before. It said something was wrong with the fuel vapor vent solenoid open or shorted. I've never replaced anything on the evaporative emission system except a hose under the hood 3 or 4 years ago. I've had to change the fuel pump a couple times. I've never had any wiring issues. I've never hacked into the wiring. I've owned it since it was new. Is it likely that solenoid is failing or the vapor canister is shot? I don't need this to happen again because even if it's in what was called limp mode. there's no way I could've driven it home like that. I couldn't even pull over. I was lucky I was still in a parking lot.

1999 ranger 2.5. 135k!So I started with a tune up all motorcraft, fuel filter and air filter. Did nothing! So I did compression check all cyc 150psi and above. So I did leakdown, had air leak at dip stick and valve cover, So I asumed head gasket. Pulled head and found 3 head bolts on passenger side had carbon deposit bluid up really bad, So replaced head gasket all surfaces clean and flat. Still didn't fix it!! My symptoms are better than before hd but still have a engine shake and flashing cel at 55 plus mph and p0303 pending! Coils tested good but going change them any way tonight!I'm stuck on this one checked everything 3 times and then again...

Ok I've been plagued with this very random misfire/power loss/hesitation problem going on a couple of months. You could drive the truck anywhere from 50-300 miles without having an encounter of this problem. It seems to do it now mostly on contiguous long trips over like 30 miles. It one time threw up a P1131 code which quickly went away on it's own. This is a list of stuff that has been recently changed: plugs, wires, coil packs, air filter, pcv valve, fuel injectors, tps, idle air valve, MAF cleaned, fuel filter, and egr valve.
I sprayed with brake cleaner for vacuum leaks around the intake tonight after driving a continuous 50 mile round trip it messed a few times on the way back. When I sprayed the EGR valve mounting area it idled rough when it was hit with brake clean and idled up. So there's a leak there. Or is it stuck? It will be driving normal and usually when you come to a stop the engine will start missing really bad and then when you take off there's no power at all. You keep your foot on the gas and eventually it will feel like all the power is just turned on.
If it does it while you're driving highway speeds it will feel like you've lost a cylinder but it's not as dramatic as when you come to a stop and it starts missing. I can't be 100% but I don't think the EGR wasn't leaking before I replaced it and it was still doing the same thing. I'm wondering why the Check Engine Light won't pick up an obvious misfire when you can you actually feel it. And why if it was the vacuum leak would it only start doing it after many miles of driving?

I noticed the passenger side on/off switch for the airbag doesn't illuminate anymore on my 98 Ranger. Whether I turn the key on the switch to on or off it doesn't illuminate either way. The airbag light on the dash flashes showing, counting a code 27 and then it stays on. I also noticed the seat belts on symbol doesn't illuminate and in the owner's manual it says it should illuminate and chime. I remember it use to illuminate but I don't remember a chime.
Someone with a 98 that has a seat belt reminder light that illuminates and chimes until you fasten the seat belt? I don't know if that and the airbag code is related. But I want to fix both? I guess the simplest one to tackle first would be the seat belt light/chime. I don't see a fuse for it. I guess I need to know first is it really suppose to chime.

I have a 98 ford ranger with a 3.0 v6 it has 228,000miles standard tranny but I keep the truck running great. I did the plugs and wires about two weeks ago and it was running fine, actually great. This morning I got into the truck to start it this morning and it barely started. It fired up but barely stayed idling. I would get into the petal and it wouldn't raise rpms. I had to get to school so I headed out. I couldn't get any speed in gear the truck wouldn't gain speed. It would sputter and pop and then all of a sudden it would go ok but then start popping again. I took it to a buddy shop and his scanner showed p1131 and p1151 both codes. I don't know what to do?

I just bought a '98 Ranger 2.5l 2wd. After driving it for a week or so I got a P1405 Code. After a quick google search I got :
P1405 Ford - DPFE Sensor Circuit Upstream Hose
Possible Causes: - Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor)
- Plugged or damaged EGR tube
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
Now, I have done my research between forums and youtube and have found this EGR system to be quite. I've gone ahead and replaced my DPEF. I took an air hose and blew out all the small lines coming into the DPEF. I still have the engine light. My next move is to get a volt meter and see if I'm getting power to the sensor.
My question is about this particular code and is it possible I need to look farther into this EGR system (EGR Valve, EGR Hose, etc.)

My sons 1998 ranger is in mph. Converting on to a kmh dash. There's one at the wreckers and I was wondering is it a direct replacement or is it a computer swap also? What years would work?

I have a 98 4x4 with 145k miles and 4.0 OHV. Symptoms are as follows;
Uses ALOT of oil. 1 quart per 230 miles. Burning bad in rear cylinders, some in middle cylinders, none in front cylinders. Screams intake or PCV issues to me, not rings or valves. Never any smoke, not even on startup. No significant leaks. MPG always 18-20mpg.
Slightly rough idle.
Miss under load below 2k rpm. Not a terrible miss, but you can feel it. Has never lit the CEL. I know the CEL is good.
Never loses coolant. No coolant in oil or vice versa. Haven't done compression test, but doesn't seem like they ever tell you much anyway.
This weekend I replaced all intake gaskets, plug wires, cleaned oil residue off and regapped plugs (they are 3 months old), injector orings, and PCV valve. Flushed and burped radiator.
It's too soon to tell on the oil consumption, but I thought the intake gaskets would have cured the rough idle and misfire. The idle IS much better, but still not perfect. But the low rpm load miss is actually worse now. Still no CEL. Could it be storing codes without lighting the CEL? Also, how do you clear codes on these, can you just disconnect battery, or do you have to clear them with a scanner?

I have been having with my ford ranger. I bought this off my nephew bcuz he needed some money and never drove it due to it being a 5speed and he has a kid and a wife and no room. OK the issue I am having is in gear or neutral I can't get the 2.5 motor over 3000rpms in any gear at all. If you rev the engine up or r driving it when it hits between 2900-3000 rpms the motor acts as if it is going to die and looses all power until you let off the gas. I have replaced the following items on the truck. Oh by the way I have a Cam 2 hand held and there are no codes or warning lights. All new parts :
1) new fuel pump
2) fuel filter
3)new timing belt
4)new motor craft platinum plugs
5) new motor craft plug wires
6)new Mass air flow meter
7) clutch,pressure plate & throw out bearing along with new slave(that needed it replaced others since I was there)
8) exhaust tube behind motor(rotted out)
9) new idle control sensor (acts as elect. Choke)
Truck starts up real quick and idles fine, but when truck is cold the rpms @ 2500 does the same as when it is warm @ 3000 rpms. I even took it to the local ford dealer in my town. Youngstown oh @ Fred martin ford. They told me the wires should be replaced and plugs along with mass air flow valve. I called them after replacing it and told them no difference and the service manager told me to bring it in again and they will look again. Service manager told me he has never heard of this type of problem and I went to a local garage mentioned it to the lead mechanic. He said that is why he doesn't like fords they are to common in chronic problems and can't be fix without a lot of guess work. I have a Hanes manual and did everything it recommends to no avail.

I've got 30 lbs of fuel pressure that drops to 28 if you rev it up a bit on a 1998 ranger 4.0 with a new fuel filter. Haynes manual say it should be 56-72 lbs. Bad news is fuel pressure regulator is in the tanks with the pump. Can the regulator be swapped out or is it one assembly with the fuel pump? Is there anything I should check first?

Ok so my dad has been using my 98 while I was fixing his 92 4.0. I had the 92 perfect and then someone pulled in front of me and totaled it out. Well now I got my 98 back and it's all messed up. Check engine is on p0171. Fuel pressure test done and it's steady 40-42 psi. I remember last year I checked it was like 68-72 psi. It hasn't been a year or two since fuel pump and strainer were replaced. Filter probably 15,000 miles ago. It's currently running good sometimes it cuts off when you start it then next time it stays running. Is this another fuel pump failure? How much longer will it last on 40 psi? The fuel lines and tank have 336,000 miles, engine maybe 150,000 and injectors have about 20,000 miles on them.

I got this 98 Ranger 2.5 that I've done a tune-up on less than 30,000 miles ago. I changed plugs, wires, and both coil packs. Timing belt, thermostat, fuel pump, fuel injectors are all recently changed too within a year or two. Fuel filter and air filter I change every 30,000 miles. The truck runs as great as a 4 Cylinder will run. It's at 344,000 miles but the engine was changed once so it probably has over 100,000 miles on it. There is just a slight miss you can hear through the tailpipe but it's not severe enough to be picked up by the Check Engine Light. In fact, even when the coils were totally gone it never put up the Check Engine Light. I can tell when a coil pack is going out on this because it's done it several times so I usually just change them with the tune-up. It's only a slight miss some people may not even notice it. I was just wondering is there any way to track down where the miss is? I tried looking under the hood in the pitch black and there's no plug arcing.

so heres whats happening. My 98 ranger speedometer has not been working since I owned it (I am the second owner who got it from a grandpa) and I've replaced the vss sensor two times, got a new connector and gave that a try and still nothing. Yes I've looked for cracks in the wire or any exposed copper, I've looked through many forums and cant figure it out. At first before replacing the vss, my abs and check engine light weren't lit up until i put a new vss sensor on that i got from o'reillys, so then i got another one thinking it was just a bad sensor and still no luck. another thing is when its cold in the morning and i get in my pickup to go to work it will start working once i go over 30 and fluctuate between that and 20 but if i don't accelerate it will not bounce all over the place.

I have a 98 Ranger SuperCab XLT 4WD 4.0 Auto. Occasionally, especially when it has been sitting for more than 3 days, it shakes for maybe 30 seconds on startup. It smooths out gradually after that, maybe 15 sec. to normal smoothness. It seems like it is firing on all cylinders and is more like something out of balance.
Never does it when sits less than 2 days. When it happens, the longer it sits the worse it shakes.

Throwing codes ... p0136, p1131, p1151 acts like it going to just stop then will take off, at a stop light it will sound like it has a large cam in it... It is a 1998 4.0 V6 automatic tranny.

I bought a '98. At the front passenger side of the engine, the injector rail is leaking fuel (a fair stream of it). I have done some googling, and browsing around the forums, and can't find much in the way of specific info on where to start with this.
Whatever the device at the front of the rail - Without digging too far, it seems that the leak is coming just below it.
Questions:
Am I obliged to change injectors with the rail?
What is involved with changing the rail? Removing upper intake only? At all?
What is the box shaped device at the front of the rail, passenger side? Test port? Pressure Regulator? Both?
I won't have a chance to work on this again until next weekend, but thought I'd try to do some homework beforehand.

I understand there is not much adjustable on my 98 Ranger (2.5L) as far as idle speed and mixture. It runs rough when started cold. Is this a sign to replace spark plugs?

98 ford Ranger 2.5L.
I have not heat from the vents, doesn't get warm at all. If I idle the enginer in 30 Degree weather it gets to almost the C.
Upper Radiator hose is hot, I have verified the thermostat is new and it opens at 192 degrees as it should. Replaced the Water Pump, Fan spins freely.
I have attempted to burp the system, it isn't kicking out anymore air from the lines that I can tell. I used a large funnel and filled it with Anti-freeze, it filled the radiator, burped the system and the reservoir filled to overflowing. All with the engine hot. (To be specific the funnel was always full of fluid so no air could get sucked backwards)
The heater core hose on the left when looking from the front of the vehicle does not get hot, the one on the right gets warm. I theorize that the heater core is clogged up somehow and that is why that left line doesn't get hot. There is no fluid in the cab of the truck from the core.
