And there is this if you haven't already found or seen it:

RESETTING THE APPS SENSOR.
(ACCELERATOR PEDAL POSITION SENSOR)
2ND GENERATION 24 VALVE TRUCKS ONLY.

LIST OF TOOLS NEEDED

DIGITAL VOLT METER
# 20 TORQUE BIT SOCKET
# 1 PHILLIPS
# 10 MM SOCKET

Proper service and repair procedures are vital to ensure personal safety of those performing the repairs. Standard safety procedures and precautions should be followed at all times to eliminate the personal injury or improper service, which could damage the vehicle or compromise its safety.
Although this material has been prepared with the intent to provide reliable information, no liability is assumed in reliance of this material.

It has come to my attention that a lot of people think by disconnecting & re-connecting the batteries and stepping on the throttle it is going to reset the apps, no, that is not correct. It is impossible to adjust your apps if you do not know where it is supposed to be set at. That is why you need the voltmeter.

This is the procedure I use to re-set the apps.

With the key on, engine off you need to probe the apps wire to see where your voltage is currently set at.
The best location to probe the wire is on the PCM (power control module) which is located off the passenger side of the firewall.

• You want the C1 connector, this is the connector closest to the engine,
• You want the orange wire with the dark blue tracer which is pin # 23
• Voltage should read somewhere around 0.5 volts,
• At this point the voltage reading does not matter, it just has to be accurately written down for later reference.

*** TURN THE IGNITION OFF ON THE TRUCK ***




Resetting the APPS Sensor cont. page 2
(Accelerator Pedal Position Sensor)
2nd generation 24 valve trucks only.

• The apps sensor is located slightly above and a little to the left of the injection pump.

• Remove the black plastic cover that is located by your injection pump.

The two screws that are holding it are plastic, do not put any downward pressure on them or you will never get them off.

• Un do the 6 - 10 mm headed bolts that hold the bracketry in place.
(DO NOT REMOVE THE CABLES)

You will notice the apps is on the back of the bracketry that you just removed, it is held in place by 2 - 20 bit screws. These screws have a little bit of locktite on them so make sure you have a good socket and gently give a little tap with a hammer before attempting to loosen. Be very careful these screws strip very easily and you only get one shot at them.

• On the apps you will find a white tag that gives you the information on what the apps adjustment should be.

• After loosening the screws you can rotate the apps both clockwise and counter clockwise to get the adjustment you need.

• The reading you took at the beginning of the process on pin # 23 should match the white tag on your apps, if not adjust accordingly.

I remember when I wrote that right after I got the valve body in my dodge. It was ground breaking at the time LOL
 
Well after changing the Apps, I think that nipped it. Better throttle response and the cruise control also works good and not jerky even with to boxes stacked.

LOL The ol VP is dead game. I am pretty sure the "other forum" has ruined VP trucks for a lot of people. I honestly like a good running VP truck with mild mods but if you ever google any issues you would think a burnt out license plate light means the VP is dying....

I'm a weird weird animal... Vp's are by far probably my favorite trucks. Jory ruined me on that. Get one around 500 horse and it is tame, can pull the mountains, and still run good enough for my liking all while being pretty reliables.

People with a little bit of knowledge realize vp trucks aren't that bad once they come to terms with the fact they probably won't realistically ever max one out and if they pay attention to fuel pressure they will last a reasonable amount of time.

It is the guys who throw a programmer on a stock truck that ruin it. "Put a danged edge juice attitude chip on and the danged thing broke. Junk vp."
 
Well I'm just thankful for finding it to be the APPS. I wouldn't want my vp leaving me stranded out in the desert.
 
nice..ez fix. i love my vp..ive got over 100k on an hrvp...my tow pig does it all and still ran a 13 at the track...i love it
 
and sweat...i probly had 4 turbos and 5 sets of inj on this truck to make it tow and still run good...some of the ''cool stuff'' didnt work
