I was hauling in some junk cars yesterday and on the way back my OD light started flashing. I was only 3 blocks from the tranny shop so i had them scan it. They said it was showing the tps was out of range and something with the FIPL switch(i am not sure what this is.) My question. Are these parts the same as the ones on my parts truck (91). The only reason i thought they might be different is my parts truck is a manual.

 

NO your 91 has manual so it does not have fipl. THe tps is the flipl you can test it just do a search and you will find how to test very simple if you have a meter.Sometimes they just need adjusted. The fipl is located on driver side of injection pump.

 

i have been searching for about an hour now if you or anyone has any pointers on how to get to that thread that would be great, do i just need a multimeter to test

 

Here is some info on the FILP (TPS) settings and adjustments.

CLARIFICATION NOTE: YOU DO NOT USE THE .515" GAUGE BLOCK
WHEN USING THE DVOM METHOD TO ADJUST THE TPS/FIPL. PLEASE
SEE ADDENDUM AT BOTTOM OF PAGE BEFORE STARTING ANY
PROCEDURE.
Correction
Check TPS/FIPL
Here's how
1. Hook DVOM black lead to battery negative cable.
2. Turn Key to on position (do not start engine).
3. Set meter to DC volts/ 0 to 40-volt scale.
Note
Leave 3-wire connector hooked up to TPS/FIPL sensor for test.
4. Probe black wire on 3-wire connector with red lead of meter. Must be less than .1
volts (that's 1/10 of a volt not l volt). Will probably read in milli-volts. This is the
ground wire. If more then .1 volts, ground is bad.
5. Now probe the orange wire. Must be close to 5 volts. This is reference voltage
sent from the controller. No voltage means an open wire between the sensor and
the controller. Low voltage means the wire is shorted to ground.
6. Check the green wire. It should be around 1 volt. Leave the red lead hooked up to
the wire and steadily open the throttle until it is wide open. You should see a
steady increase in voltage up to 4 to 4.5 volts, with no fluctuation. Be careful! If
you open the throttle to fast the DVOM will probably show 0 voltage or out of
limits. This is normal. If the voltage does not increase at all the TPS/FIPL is bad. If
it is below 1 volt and never gets to 4 volts, it might just need to be adjusted.
To Adjust FIPL if you don't have a scanner:
1. Loosen FIPL adjustment bolts.
2. Hook DVOM black lead to battery negative cable.
Note
Leave 3-wire connector hooked up to FIPL.
3. Turn key to on position (do not start engine).
4. Set DVOM to DC volts/ 0 to 40 volt scale.
5. Probe green wire (center wire) with red lead of meter.
6. Idle- 1.1 to 1.4 volts.
7. Wide open throttle- 4.1 to 4.5 volts.
ADDENDUM TO ABOVE TEST AND ADJUSTMENT PROCEDURE (Provided by
direct experience from Ford Truck Enthusiast Message Board Member, RxF, which may
help you get insight and verify what your own Throttle Position Sensor or Fuel Injection
Pump Lever sensor is doing. Note: this was taken from a thread in the Pre-Powerstroke
Diesel Section but should mostly apply to the TPS on gasoline engines as well; edited
some for succinctity)
A Note on the Gauge Block:
If using a DVOM to adjust the FIPL sensor, you DO NOT use the .515" gauge block. The
gauge block is only used when adjusting the FIPL sensor with a Scanner Tool. WOT
(Wide Open Throttle) is literally when the Fuel Injection Pump Lever is moved all the
way from it's idle position to when the Maximum Throttle Set Screw (DO NOT ADJUST)
makes contact with the Injection Pump Maximum Throttle Stop.
" The gauge block is only used with the 'scanner tool' or a resistance adjustment
procedure I've seen. From reading that procedure (the above procedure not in italics), it
was not initially clear to me that this was to be done without the gauge block. The
confusion came because the DVOM voltage adjustment procedure was described as an
alternative to the (preferred) scanner-tool procedure. The scanner procedure was
described first and mandated the gauge block use. The verbage should have made it clear
not to use it when performing the alternate procedure.
The following was verified on my truck:
Reference Voltage= 5.04volts
Ground Terminal Voltage was 18 millivolts (.018 volts) after cleaning grounds.
So the system environment I put the FIPL sensor into is good.
Final Adjusted FIPL sensor results:
Idle: 1.33v, WOT: 4.03v
These numbers were the best I could get with the 2 FIPL sensors I had, one not too old
and the other brand new.
The FIPL sensors (either one) have a Resistance Total equal to about 4.57kilohms.
There is just about 1.1 miliamps (1.1028 ma) of current drawn from the reference supply.
With the gauge block in place, the FIPL sensor had a Center Terminal to Ground
Resistance of 1.9 kilohms. Then, with voltage applied, the center terminal generated 2.25
volts with the gauge block in place. THIS MEANS THE GAUGE BLOCK PUTS YOU IN
A MID-THROTTLE STATE.
HELPFUL HINTS:
1. Probing the FIPL sensor Voltages: Do this from the back (wire side) of the FIPL
sensor. There is a polyurethane grommet that is grey in color which the 3 wires enter the
harness connector through. This grommet is easily removed with a screwdriver w/o
damage. When done with testing/adjustment, apply a slight film dielectric grease on outer
edge of grommet to ease insertion into 3-wire harness connector and provide an
improved seal.
2. Prior to adjusting the FIPL sensor, disconnect the electrical connection to the Fast
Idle Solenoid. This ensures that when you have the ignition switch on, the solenoid
plunger does not engage and there will be no voltage discrepancies when adjusting the
FIPL sensor idle voltage. Be sure to re-connect the fast idle solenoid once you've gotten
the FIPL sensor adjusted."

thanks gumper i will let you know how it goes

 

So everything checks out good except for the resistance that i found on an article that david85 posted. It said that the resistance between the top two wires should be 1800 +or- 50. The highest i could get was about 1198. I am assuming this means replace and set to these numbers
