Originally started with a p0302 code, and it cleared. CEL came back on with codes p1131 and P0401. First time with an 8 plug 4 cylinder. Truck has 263000 miles, and still original (metal) DPFE sensor. 1996 ranger 2.3L.....
View 1 RepliesThe Explorer ran just fine last week, until I tried to clear a chronic (months) "Check Engine" light. Initially the only 2 codes were pertaining to the DPFE sensor and Cylinder #1 misfire. I found an aftermarket rubber hose from the DPFE that had rotted off. I replaced the rubber hose, and I replaced the #1 spark plug and wire. Instead of simply clearing the codes and turning off the "Check Engine" light, it now shakes to the point where it's barely drivable. 57 mph seems to be the "sweet spot" where the shaking is the worst, but it will also shake under heavy acceleration, and when driving uphill at freeway speeds. Taking your foot off the gas seems to decrease the shaking somewhat. The weather had been unusually cold (for South Texas), and as the weather has warmed-up, the shaking seems to have diminished, so there may be a connection between the shaking and the temperature.
OBD-II Trouble Code: P0301 Cylinder 1 One Misfire Detected
OBD-II Trouble Code: P0401 Insufficient EGR Flow
I have a lot of questions, but do not want to cloud the 1st post of the thread with information that may be irrelevant, so I'll leave it at that. This is my work vehicle and I'm in the middle of a job and am worried that I may be causing permanent damage to the vehicle by driving it. I know I can change-out the DPFE sensor and the ICM, but as they are both non-returnable parts, I don't want to spend the money without good reason.
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 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?
View 13 RepliesI have a 2000 Ford Ranger 3.0L engine, 2 wheel drive, with automatic transmission. Check engine light came on about 3 months ago. checked with scanner and P0401 EGR flow insufficient came up. cleared it and it came back. truck seems to be running fine. I didn't take autoshop as a kid, so i probably will need a little hand holding on this one.

What I did: Changed the exhaust manifold gasket on the right side. There were some broken studs which came out with a stud remover.. No torch was used during this evolution.
What happened: After driving 10-15 miles it set the codes that I listed in the subject line. Reset the codes 20 or so miles later the P1131 code set again. (both times there was a noticeable loss of engine power) The upper O2 sensor checked out with a meter. When I checked the voltage on the truck's harness plug referenced to the NEG terminal on the battery, both the power and gnd had 12V- Key On Engine Not Running (KOENR).
What I did: Cleaned the connections put dielectric grease in the connections and reassembled. Reset codes; all was well ~ 100 Miles later the codes are back. I also ran a continuity check from the plug to the control module, they check out fine.
My 96 ranger had lost a brake pad coming out of the mountains. I replaced the rotor but the ABS light came on as well as the check engine within a week. Several issues the clock spring was bad, replaced. The cam position Sensor was bad, replaced. I had this at a shop in a small town. While I was there they ran diagnostics.
At first the ABS module was sending data and gave them some info. Suddenly there was no more data stored in the module. They ordered a new ABS module installed it and replaced the LF sensor cable. Both sensors were cleaned prior to this.
The new abs module required a trip to ford to reprogram. At the shop they still could not get the light out. I took the truck home to my ford dealer and they said bad abs. Got a new (rebuilt Mfg discontinued) Installed and ford said this was bad with a code c1102. 4 w 4wd installed needs 4 w 2wd. ordered a new abs. Ford said same code again and the tech said that the ABS is not communicating through the obdii port.
My thoughts are the reader they used at the small shop was defective and either shorted out something or blew a fusible link. I am told this is 4 wheel abs with the rear sensors are on the pumpkin but after looking at the diagrams I do not see a RABS fuse. I have tested all fuses, and the shop replaced several relays. The pcm and ABS diodes check ok. Perplexed.
My engine has 2 ignition coils, and b went bad, but which one is b. ?
View 9 RepliesI have a 1996 Mazda B2300 & I heard that it is similar to the Ford Ranger.
Well the thing won't crank or start.
This is what I have done so far. I wanted to put a RPM meter on it. I followed YouTube videos on how to do it. I cut the Tan wire w. the yellow stripes & try to connect the wire to thr RPM meter. Then it won't start soo idk what to do. I also took put the PCM too. (I was looking for the wire) Now be honest, I talked to a mechanic, he said thag I might have blown my PCM or Blown another fuse. But when i put the key in to crank, it won't start ot click at all. The lights come on & it wants to start but won't start.
Then my mechanic tried to start it by the... Idk what it is called but you can start it & it wont evet start. It will crank like crazy but will not start at all.
I have a 96 Ranger 3.0 auto that is hitting 300,000 miles. I've got a 302 that i build for my F150 but know i'm thinking of transplating it in the Ranger. Is it a big deal in putting a SB in place of the V6.
View 4 RepliesI seen on this site awhile ago something about a fix for the heater control door, I have a 1996 Ranger and all I have is Hot heat and cannot cool it down with the temperature control.
View 2 RepliesI have a 2000 with a 5.4 and 166K miles. It had multiple exhaust manifold studs broken on both sides. Now that thay is fixed, I am getting the p1131 and p1151 codes. The EGR tube was also replaced at the time of the manifold fix. I checked over all the tubes and electrical connectors to rule out something simple but did not find anything out of place. The intake manifold was replaced with a new Napa one less than 5K miles ago as well.
Could the leaky exhaust manifolds over time set the fuel trim level high and now that they are fixed, the ECM is thinking it is running too rich? Can the ECM be reset to zero? There is also a ticking/rattling noise when you accelerate that seems to be coming from the fuel injectors. I listened with the stethescope and they are the only things that sound like the noise I hear. Could these all be related?
Working on a friends 94 ranger, 2.3 L with codes 218 and 998. Chiltons manual does not even show this code. Code is for Loss of Ignition Diagnostic Monitor (IDM)/left side. What exactly is this? Can't find anything that explains the IDM.
998 means a hard fault.
I'm in the middle of replacing my pump. With the new pump are a plastic washer and a small rubber o-ring but no instruction where they are supposed to go. They didn't know at auto zone and I haven't heard them mentioned on any youtube video. I found a crushed torn up washer similar to the plastic one in my catch pan. Maybe it is supposed to go in around the high pressure hose connection.
View 6 RepliesI am working on a 96 ranger 2wd the front brakes were shot or nearly so,about 1/8 in left and cracked. Changed them this morning at 5am because that is the cool of the day (104 today) everything up front works fine but the howling and nails across the chalk board from the back was still there. Took it to my freindly les schwab and they told me it needed axle seals on one side and the noise is from the gear lube on the shoes. they wanted 800 bucks to fix everything, went and bought new shoes,new seals,gear oil,and gasket for rear end cover it is an easy half hour job. As I was driving home tonight from the parts store the noise stopped so now i am worried either it was a rock stuck between the drum and backing plate or something broke. everything sounds and works fine....
View 2 RepliesI have a 96 ranger with a 4.0 and an automatic transmission that has a horrible oil leak when cold. The leak looks to be coming out above and behind the oil filter. After running for a few minutes the oil leak appears to go away.
View 6 RepliesMy ignition key is stuck / locked in the off position. The first time this happened I jiggled the key while moving the wheel back and forth and it turned. The next time in the truck nothing worked. I let it roll back a bit then tried, pushed the clutch in and put it in neutral, etc it did not move. (Just had the clutch and clutch hydraulics replaced.) The wheel is locked. The key removes from the cylinder.
I know it is easy to replace the Ignition Lock Cylinder when you can turn the key in the run position. How to remove it when locked in off?
My 1996 Ranger Supercab XLT has the stock radio with 6-cd changer. The unit works fine but only the frequency/clock display lights up. I'm not sure where to start to fix it.
When a problem first occurred, the frequency/clock display flickered/dimmed randomly (and I think the other lights were fine). It was in the shop a few times for a fuel pump problem (the after market pump was actually not compatible and it took a bit to figure that out), and at some point after I got it back I noticed the display was fine but the remainder of lights didn't work.
I don't know if the shop did something or the failure behavior changed. What to look at? I can open the radio and fix that if needed (or replace it).
I have been hauling a lot of garbage with my 96 ranger this last week. The differential has been making a little more than usual noise like growling, but it has always been smooth, now all of a sudden it shakes like a tire out of balance up to about 55 then it is like a switch is thrown and everything quiets down and the shaking goes away, until i get around 55. I haven't climbed under the truck yet just checked the tires and grabbed the drive line they are all ok,i don't see any leaks so it is a head scratcher. Hopefully it will be something easy, but it hardly ever is.
View 7 RepliesI have a 1996 Ford Ranger with 95k miles on it. Recently, my truck's automatic transmission has been slipping really bad. I'll be driving down my road and while going around a turn, the clutch feels like it randomly disengages, so when I press on the gas, it feels like I'm revving my truck in neutral, and then it will all of a sudden get back into gear, violently a lot of the time. However, once the truck is warmed up, the it runs perfectly and never slips. I've checked my oil multiple times and even changed the oil filter in the transmission. I am not sure if this has anything to do with it, but if I let my truck idle in park for a little bit, the RPMs will increase and if I shift in to reverse or drive while the RPMs are high, it'll do the same thing.
View 14 RepliesMy son just purchased a 1996 Ford Ranger 2.3l 5 speed it is a nice little truck. But I have a question when you press in the clutch it acts like the choke has come on it idles way to high. When you come to a complete stop it is a few minutes before it goes back to its regular idle. Is it suppose to do that?
