#171 of 189 Re: 2004 Ford Explorer misses at 56 mph [wwest]
Jan 19, 2012 (1:36 pm)
I've seen this on an 04 F-150. Using the tach, check the RPM at 56 MPH. Now find a section of road where you can hold it in 1st gear and do a very gradual accel through that RPM point. (Not too fast or you'll drive right through it.) If the miss occurs at that RPM then you may have an issue with the Crank Position Sensor (CKP) wiring.
There's a variable reluctance sensor. and it is triggered by a 36-minus-1 tooth trigger wheel mounted on the crankshaft . The sine wave output is via a twisted pair, but if one wire is open or grounded then a miss will occur due to the designed CKP software edge transition.
At low speed it reads all tooth edges, but as speed increases it has to shift to counting every other edge. The software designer picks an optimal transition RPM, and all is good unless one CKP wire fails. Then the PCM goes through a momentary reset which ends up as a miss.
It usually won't hurt the vehicle, it's just annoying when you drive at that point. Look for pinched or corroded wiring between the PCM and CKP sensor.

Again, your expertise is respected and valued, but your insult to owners by calling their truck an "exploder" is not appreciated nor respected. Must you? The visitors here may have a problem, may not even be happy, but it's their car. They chose it, they own it. And they may like it. I've had 8 of 'em. Some were better (140,000 trouble free miles) than others (65,000 trouble free miles), but I do love the superior design of them since inception. Which is why I'm on my 8th one.
I have pretty much zero respect for GM, but I don't insult the owners.

The "moniker" was chosen to denigrate the Ford model, the "Exploder", not the owners in any way.
The term arose out of the tire under-inflation episode that Ford themselves caused. Even worse they decided to place the blame on the tire manufacturer, even won that point in court, rather than take responsibility for their own idiocy.
And the now we come to the new models being converted to FWD, or should I say the FreeStyle, Taurus X, failed in the marketplace models, have simply been renamed in order to benefit from the buying public's faith in the "Exploder" name.
I have never really liked, been a fan of the 4runner, but I would direct anyone considering purchasing an Exploder take a long hard look at the 4runner.

Ok, I'll bite. NHTSA also cleared Ford of the blame for the rolling Explorers, because, virtually all of the trucks that rolled, were on Firestones. Those with replacement tires, or OEM Goodyears, or BF Goodrichs, for some odd reason, didn't roll. Firestone found the defective tires, and the plant that manufactured them, which was cutting corners in the manufacturing process. The Firestones failed from heat, worse in South American heat, rarely had a problem in Canada. Underinflation only exacerbated the problem. But one more time, only on the Firestones. I owned a 97 with those tires.
Car and Driver did their damndest to replicate the phenomenon. Blew up numerous tires on the back of Explorers - couldn't duplicate the rollover.
So Ford bigots like yourself will ignore the evidence that the Government, the Courts and the Media have concluded to be correct - and blame the car. But you're wrong. And your credibility with me just expired.
As for the 4 Runner. I like those too.
#175 of 189 2002 Explorer 4x4 High light flashing
Jan 25, 2012 (8:47 am)
I have a 2002 Explorer XLT with about 108,000 miles on it. About a year ago my 4x4 High light would flash 8 times every 3 or 4 minutes. It made a noise like it was trying to throw itself into 4 wheel drive when I was driving anywhere and made a grinding noise when turning to the left that sounded like it was metal on metal. The eletronic shift motor, transfer case control module, and all sensors were replaced.
I've now been greeted by that little flashing light again. The local Ford dealership ran a diagnostic scan and it basically indicated that the same parts need to be replaced. Is it really possible that all of those things could be bad again? I know it isn't the dealership trying to milk any money out of me. They didn't know that those things had been replaced before or that the computer's history had been cleared after the repairs previously.
I seriously want to just pull the sensors out of the control module, but I can't seem to fit myself under the glove compartment and the cover is bolted in place. I believe that I'm going to try to remove the glove compartment today and give it another try.
Has ANYONE else had this problem?

Think about it, more seriously...
Ford engineering realized that the Exploder had to great a tendancy for rollover.
Ford design engineers decided that the fix would be to recommend lowering the factory recommendation for tire pressure in order to lower the center of gravity.
Sound like a good deisgn approach to you, anyone...??

I am having the problem with the 4X4 light coming on too. Then everytime I put it in reverse the 4x4 seems like it kicks on. Have you found anybody to fix it? I'm looking at transmission shops to take it to today. The transmission also stutters alot when I'm driving on the highway. Scares me!

I HAVE A 2004 FORD EXPLORER. IT HAS 109K MILES.MY 4X4 HIGH LIGHT COMES ON AND SOMETIMES WHEN I TURN RIGHT MY 4 WHEEL DRIVE BANGS IN. THIS ONLY HAPPENS WHEN I TURN RIGHT. MY ABS LIGHT USUALLY COMES ON FIRST, BUT, NOT ALWAYS. THE 4X4 HIGH LIGHT WILL BE FLASHING. SOMETIMES IT GOES OFF WHEN I CLICK 4X4 AUTO NUMEROUS TIME. ANY SUGGESTIONS AND DETAILED INSTRUCTIONS WOULD BE GREATLY APPRECIATED. THANK YOU ALL, SLAMMIN IN 4
