The most common problem when a APPS sensor is failing is a "Dead Pedal" You'll be driving down the road and hit the go pedal and NOTHING. A real annoying problem. The most common codes are the 0121, 0122, 222, or 223 code. Another issue is a surging or a bucking, this often times will not throw any codes. The other cause of the "Dead Pedal' is a failing vp-44 injector pump, I have those available (for less than $1000) . Common codes for Injector pump are 0215,0216,0251, 0252,1688,1689
These commercial grade Sensors are a direct bolt in replacement on a 24V 98.5-03 and some 04 trucks. 04 look at the engine bay picture Take notice to the large black plastic cover in the center of the picture. That is the APPS assembly, if you have that then this Sensor will work for you.
Item carries a 1 year warranty from time of receipt. To have item warranted you must contact us prior to removing item from the truck. Troubleshooting must be done prior to return to verify the type of failure of the product. Once the problem is determined an RMA number will be issued and shipping arrangements will be determined.
APPS SENSOR INSTALLATION INSTRUCTIONS
1. Disconnect battery cables
2. Remove the plastic APPS cover.
Next remove the six, 10 mm headed bolts that hold the bellcrank assembly on.
When that is removed, you will see the sensor on the back. A T20 Torx is
needed here.
*Caution, these screws have loctite on them. So make sure that the bit is
engaged fully into the screw head, so they do not strip, or you will need to use
visegrips to remove them. NOTE: 2 new screws are provided.
3. After the old sensor is removed, take the new sensor and look at the side
that bolts to the bracket. In the center, you will see the slot that engages in
the tang of the bellcrank shaft. Next, line up the slot with the tang and push
the sensor onto the mounting surface.
*If a sensor does not mate flat to the mounting surface, the slot is not engaged
properly, try again.
4. When you are sure the tang is engaged properly, rotate the sensor clockwise,
until the screw holes are aligned, and start the screws. Just before the
screws are tight, twist the sensor clockwise and tighten the screws.
5. Remount the bellcrank assembly to the bracket.
6. Next procedure is setting the idle voltage, using a digital voltmeter, and
turning
the idle stop screw clockwise.
*Caution, the screw has loctite on it from factory. You will need a T20 Torx
bit with a ¼ inch ratchet to turn it. Make sure the bit is engaged fully into
the head before attempting to turn. Be careful not to strip the torx head!
*If needed, a propane torch, VERY CAREFULLY, can be used to heat the screw; this
will soften the loctite and allow it to break free. Only heat it for a couple
seconds at a time and attempt to turn clockwise.
Next look on the back of the 6 pin electrical connector, it is numbered. With
the paperclip provided insert it into the back of the connector PIN # 3
(Green wire). Or insert it into the back of the factory plug(light blue wire
w/black tracer) just make sure its PIN #3. This will get hooked to the
positive lead of the voltmeter. The ground lead can be hooked to the ground
terminal of the battery. Turn your voltmeter to the low voltage DC scale. Make
sure paperclip does not contact ground. Proceed to plug the sensor into the
factory harness and then hook the batteries up. Turn the key to the ON position.
Now read the voltmeter, it should read .580-.670. Next turn the
idle stop screw clockwise, NOTE you may turn for a little bit before the voltage
actually rises. As soon as the voltage begins to rise, turn the screw backwards
½ turn and you are done with the idle screw.
7. Turn key off, disconnect voltmeter, and pull paperclip out of pin #3.
8. Last procedure, turn key ON, press accelerator petal slowly to the floor and
then
let up slowly. Turn key off. Repeat this 2 more times and you are done.
It also will fit all Ford and Freightliner applications that use the
VP44 fuel system, built before 1/1/2004, that have the APPS mounted on
the engine.
This has a 1 year warranty from date received. To receive warranty you must contact us before removing the part from the truck.
Troubleshooting must be done prior to return to verify the that it is a
failure of the product and not another part of the electronics system. When it is determined that the TPS is faulty we will issue an RMA. If you would prefer to have a warranty item cross shipped (ie shipping another part before the item is returned) you may put a refundable deposit down to reduce downtime.
