      Got a problem on the gearbox in '97 4.0L V6. o/d light flashing, code read using scanner gave code P01746. PCM has been checked as okay as has the gearbox (which has been rebuilt then re-checked to disount as problem). Reckon I've got a wire broken between PCM and gearbox.

      Can anybody provide me with a pin layout of this PCM? That way I can check for continuity etc. without stabbing in the dark

      more than likely your right - a broken/cut wire. Just check down your whole harness. Also, I would get a pin out from someone over there with you, cause the computer layouts may be different than over here.

      Thank you Drew - I wqs afraid you might say that, course you know how thick the loom is that runs from the PCM and where it goes :-( nightmare of a job to check the whole thing from PCM to gearbox.
      Is there anybody reading this that lives in the UK that could provide me with a pin layout? F77F .... BGB or TZP1

      Welcome to this forum! Check the plugs on the wiring harness going to the transmission. It might be possible that there is a bad connection from a dirt build up, or from corrosion. WWW.AutoZone.Com has wiring diagrams on their website. You could also download a Ford CD from WWW.FordCDs.Com.

      You guys are amazing!! I've been trawling sites under every possible Ford and/or Explorer search for days - and there's the answer in no time at all. Glad I joined the forum - thanks very much indeed :)))

      dogfriend: would you happen to have a pin diagram for the 60-pin ECM/PCM? Having trouble finding one, would really appreciate it! 93 Ex EB.
      Thanks

      Here is the pinout for a 1996 4.0 OHV

      Between this and the 2000, you should be good, I dont think there was many changes besides the 96-97 and 98-01

      Holy crap. Ask and thou shall receive! The one that BrooklynBay posted was closet to mine. I was looking for the oxygen sensor wire's at the PCM. Turns out that mine are #29 and #39 pin. Same color wire as BrooklynBay diagram. Saved allot of time, thanks for the help guys.

      Thank you!

      Hey INH, Thanks for posting those pinouts.

      I'm using the one for the 2000 model year, 4.0 L, OHV. My explorer is actually a 1999. What do you think.

      I used to work at a ford dealer, god sometimes i wish i still did... I used to post stuff like this over at thedieselstop.com myself...

      I'm a pretty good troubleshooter, Just cant afford alldata or ford online access right now, for the right info.

      Again, Thanks much for posting those.

      97 or 98 SOHC PCM pinout?

      Does anyone have a copy of the 97 or 98 SOHC PCM pinout? I'm trying to find out what pin controlled the variable induction system (variable length intake runner).

      The one I posted above (the first one in this thread) is 97 SOHC.

      97 PCM diagram

      Thanks dogfriend. That one doesn't show the pin for the connection to the vacuum solenoid that actuates the variable length intake runners. I found a 1997 SOHC engine wiring diagram on AutoZone that shows pin 46 going to an "Inlet Air Control Valve" in addition to pin 83 that goes to an "IAC Valve". Pin 46 on your diagram is listed as not used. I guess I'll connect a voltmeter to the brown wire going to Pin 46 (if I have one on my 2000) and see if the voltage changes when engine speed is less than 3,000 rpm vs greater than 3,600 rpm. That way I'll know if my PCM software still contains the variable induction capability.

      That's it!

      Page 23-6 clearly shows pin 46 connected to the air inlet control valve (solenoid). I tried separating the wires in the bundle on the engine side of the main engine harness electrical connector mounted in front of the ignition coil pack and looked for a brown wire. The colors are faded so I may have found one but I'm not sure. If I disconnect that connector will I be able to find pin numbers that correspond to the pin numbers at the PCM connector?

      I really appreciate you posting all of the PCM related diagrams. It is a real service to me and other forum members!

      The diagram for the connector should match as you are looking at the connector face (after you disconnect it). You should also be able to orient it by looking for the color codes on some of the connections (e.g. Pin 1) and matching it that way.

      It is possible that the version of the manual that I have is an early edition and that they may have corrected the manual to show that circuit in the connector in a later version. My manual isn't from "official" sources.
