I am working in Iraq and trying to fix my truck at home through my wife. Does anyone have pics of the APPS sensor on a 2002 that I can send her?

Not sure what year APPS. Found this info on another forum.


1st info:
For both an ECM change and an APPS change you have to unhook batts (already done per R&R procedures), reconnect them, turn key ON, and then depress the accelerator and slowly release it to allow the EMC to learn the idle voltage.


2nd info:

Here is how to reset the APPS.

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 ***

• 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.

Are You Shure thats the problem ? You dont want to spend that kind of money and it does not fix it..

Just Asking..

Will the APPS sensor from a 2000, 2001 fit on a 2002? I found one cheap but don't know if it will fit and the doge dealer here is closed and not all that helpful when they are open!! Thanks. Please let me know, djantie@***.net Thanks!
