FIPL Sensor (TPS) Replacement - Diesel Forum

Can anyone tell me what tools I will need to replace the sensor? I am 2 hours away from my truck and I don't feel like hauling all my tools out to it. Thanks.

Torx screwdriver set or socket set in smaller sizes #15 comes to mind. You can use the larger bracket bolts if required 7/16-9/16 and metric wreches.

FIPL set to specs:
With a warm engine and the idle speed set to your engine specs probably 650 in drive (curb idle).

Now with key on engine off. First connect the negative lead of a volt meter to the negative battery post, then place a paperclip straightened to slide up the side of the center wire for a good contact, touch the positive lead to the paperclip. Electrical connector must beconnected to the FIPL.

If your FIPL requires resetting loosen the small torx screws and attempt to attain the correct setting. You can loosen the large bolts on the bracket if necessary but try to retain the centering on the FIPL/blade.

Your trying to get closed throttle voltage: 1.1 V, wide open throttle voltage: minimum of 3.8 V but not more than 4.3 V.

If you can attain those #s then tighten the screws/bolts and ensure the voltage is at the correct setting after tightening. You can also do a slow sweep of the fuel lever from idle to WOT to see if there are any blanc (dead) spots, much easier with a really $$$ meter with capture mode. If you still find there are hard shifts or very soft slippery shifts you can adjust to suit your driving but be warned slippery shifts will burn the trans up.

The torx head screws that are the FIPL adjustment screws are a T-27. Tim

AS I'm looking at it from the drivers side, wich way increases/decreases voltage?

If I don't have a volt gauge, can I just turn it a little and see if it feels right? Mine is turned all the way counter-clock-wise. My tranny seems to be grabing to hard, so wick way would I want to turn it? Can I just do that and test drive it?

You "could" do that but, I don't recommend it. These trannys are very touchy. I would just get myself a $10.00 meter and set it properly. This way if you can't get the correct setting, you know that it needs to be replaced. Very easy to replace and set. [img]/ubbthreads/images/graemlins/smokin.gif[/img]

Replace it and get yourself a multimeter to calibrate it.

This can't be set by ear.
