Discussion Starter · #1 · Sep 22, 2009 I heard form one of my friends during my engine build that the 5.0 and 5.8 had crankshaft postion sensor. I know this is a very important sensor if it does have it. I have a 1995 bronco with a stroker 5.8 but I have a 1994 ford brocno 5.0 computer, its the eec-IV. Anyone knows I would greatly appreciate it, this is the last step in my project. Joined Feb 15, 2008 · 218 Posts
as far as i know there was no crank position sensor i know my 94 ranger has one but your bronco i dont think will have one Joined Mar 19, 2009 · 2,082 Posts
IIRC only trucks with OBD-II (~95-96) have the crankshaft position sensor. If you are using this motor with a EEC-IV you do not need nor have a connector to hook it up. Joined Nov 30, 2005 · 17,892 Posts
:stupid No CKP sensor on these trucks. The 1996 MY had a misfire detector, which uses the same principle as the CKP to operate, and in fact looks much the same. However, it was not used for anything but misfire detection, part of OBD-II requirements. Hope you've got a chip on that PCM to reflect the displacement change. Joined Oct 30, 2008 · 215 Posts

in a round about way, it does have a crank posistion sensor. the ECM needs to know where #1 is in order to fire the injectors at the correct time. the pip sensor detects #1 from the metal wheel inside the dizzy when it is spinning.

and therein lies the "problem" of accuracy. The timing set and cam/distributor gears will introduce error, whereas a system like EDIS with a CKP/VRS will indicate actual crank position. Can you tell I've looked into converting to EDIS? :toothless Joined Oct 30, 2008 · 215 Posts
Discussion Starter · #8 · Sep 23, 2009 ok now Im alittle confused, what exactlyis a pip sensor I have never heard of this, I saw the word conversion that obviously means better lol so what do both of these things mean.

PIP == Profile Ignition Pick-up, the Hall-effect sensor that sits in the bowl of your distributor, and sends a PIP signal (Ford was very original in naming these signals, wasn't it?) to the TFI ignition module and/or PCM, depending upon the year and so forth. This is the only means of the PCM seeing where the engine is, relative to crank & cam
positions. I'd highly recommend picking up a Haynes manual and reading through it, especially the parts on engine management, if you're doing a MAF conversion. What are the symptoms of a faulty crankshaft position sensor?Symptoms of a Bad or Failing Crankshaft Position Sensor. Issues Starting the Vehicle.. Intermittent Stalling.. Check Engine Light Comes On.. Uneven Acceleration.. Engine Misfires or Vibrates.. Rough Idle and/or Vibrating Engine.. Reduced Gas Mileage.. Can I just replace a crankshaft position sensor?While the crankshaft position sensor is a pretty sophisticated piece of equipment, and you might be intimidated by the idea of replacing it yourself, you probably shouldn't be. With a good set of instructions, the right tools, and some effort, you can replace your crankshaft sensor yourself.
