First tho check here is the connection , because there's a possibility that you have a bad conenction or some problem with the wiring that you may want to check for this.
Remove all the wires connected externally and then try as some of the wire has got loosed and not supporting the device to work properly.remove the wires and then reconnect it properly.

Due to the amount of images FixYa can not handle them into one thread. Please e-mail me for the diagrams (PDF Format) at [email protected].
Timing Belt Service 2002 Kia Sedona 3.5 liter
Removal
1. Remove the engine cover
2. Remove the drive bell.
3. Remove the idler pulley, crankshaft pulley, power
steering pulley and tensioner
pulley.
4. Remove the upper and lower timing belt cover.
5. Support the engine with garage jack or special tool, and
then remove the engine
mounting insulator.
Caution: Take care not to deform the engine oil pan.

6. Remove the auto tensioner.
Notice: Rotate the crankshaft clockwise and align the timing
mark to get the No.1
cylinder's piston be in TðC position (compression stroke).
At this time, the timing
marks of the camshaft sprocket and cylinder head cover
should coincide with each
other.

'. Remove the timing bell.
Notice: When re-using timing bell, make sure of marking the
rotating direction on
the belt so as to install correctly.

Installation
Method of installing timing bell and auto tensioner
Image 4
1. Install the idler pulley to the engine support lower
bracket.
Image 5
2. Install the tensioner arm, shaft and plain washer to the
cylinder block.
Tightening torque: 35 -55 Nm (350-550 kg-cm, 25.82 -40.57
ft. lbs.)

3. Install the crankshaft sprocket.
Notice: Confirm if timing marks coincide with.
Image 7
Caution: Align the spacer with a pin, and assemble it
exerting even force not to
deform the crankshaft sensing blade.

4. Install the camshaft sprocket. Align it like initial
state as shown.
Caution: When installing camshaft sprocket, tighten the bolt
holding hexagonal
part of camshaft to prevent it from tuning.
5. Install the auto tensioner to the oil pump case.
Image 9
Caution: At this time the auto tensioner's set pin should be
assembled completely.

6. Align the timing marks of each sprocket and install the
timing bell, maintaining the
proper belt tension between each shaft in this order.
Crankshaft sprocket -> Idler
pulley -> Left bank exhaust camshaft sprocket -> Left
bank intake camshaft sprocket
-> Water pump pulley -> Right bank intake camshaft sprocket
-> Right bank exhaust
camshaft sprocket -> Tensioner pulley.
Caution:
1 As a result of this, position of No.1 cylinder comes to
compression TDC.
2 As each camshaft sprocket tends to rotate by itself, pay
attention not to injure
fingers or other bodily part. Especially be careful with the
right bank.
3 In case the right bank camshaft sprocket rotates
excessively, be cautious not to
rotate more than the initial stable position. Always align
timing mark of rotating
sprocket by turning it reversely. In this case, pay
attention not to rotate It
reversely from the initial position. (if. with one sprocket
fixed at No.1
compression TDC position, the other sprocket is rotated one
revolution
clockwise or counterclockwise, then the intake and exhaust
valve might intetfere
each other)
7. After installing the timing bell, exert the reverse
directed force to the right bank
exhaust camshaft sprocket to give tension on the belt.
Holding this state, recheck it
each timing mark is correctly positioned.
S. With tensioner pulley slightly pushing the belt down,
tighten the center bolt
slightly.
9. Pull out the auto tensioner set pin
How to adjust timing belt tension
1. Tension setting (While auto tensioner is not operating:
And set pin being kept
installed.).
1) After rotating crankshaft 1/4 revolution reversely, rotate it clockwise to position
No.1 cylinder at TDC. Then, loosen the center bolt and give
the belt 50 kg-cm of
tension with tensioner pulley socket (Two pins are attached)
and torque wrench.
While maintaining this state, tighten the center bolt to the
standard torque.
Center bolt standard torque 43 - 55 Nm (430 - 550 kg-cm,
31.72 - 40.57 ft. lbs.)
Image
2) Pull out the auto tensioner fixing pin.
2. How to check tension (While auto tensioner is operating:
and fixing pin being
un-installed.)
1) After rotating crankshaft 2 revolutions clockwise to position
No.1 cylinder at
TDC wait for about 5 minutes, and measure the amount of
protruding of the auto
tensioner rod.
Caution: This is "leak down" time for the auto tensioner rod
to protrude 1mm
when tension caused by rotation of the crankshaft has
changed.
Image
2) Check if the amount of rod protruding is in the range of
3.8 -4.5 mm.
3. Recheck if each sprocket is within the specified range.
Notice: ¡fit is not within the specified range, repeat from
procedure 6 as service
procedure of timing bell and auto tensioner installation
method. Refer to Timing
Belt; Service and Repair.
