The best way is that your RUN the scanner/computer for real diagnostic and fix it. However I see that replace has nothing to do with the display. see the diagram attached.
God bless you

suspect you activated one of the air bag sensors. it takes activation of two of three sensors to blow off the airbag. have the airbag system scanned to see the sensors as to which one is causing the problem. there is also a chance that a loose connecter may have come off an airbag sensor from the jarring of the bump. either way you will need to get scanned to find out whats going on.

SOURCE: my dealer says the switch for the windshield

The cost of your part retail and NOT dealer (dealers usually mark WAY UP) is about $195 you can see one here.

The issue is that the wipers are controlled on the turn signal column, etc. So whole part has to be replaced. Dealer labor rates run about $85 per hour and the book says this is less than 2 hour job if done right. Be careful if you want to do it yourself as you will be working with the electrical in the steering column and the airbag is located in that area. Ive seen accidental activations by shorting out wiring.

If this is the 4.0L engine it is very common to have the Air Intake Plenum gasket crack. About a $30.00 part and 2 hours labor.
First, see if you have any codes. For the situation I describe about you should see P0171/P0174.
The other sensors could also be the issue. Most ODB-II scanners will allow you to read "live data". This will go a long way in telling you where the problem is.

did you reset the codes first after new parts>???????????
misfire #3 and 6( repeats)
that is because misfire has 3 causes.
those codes really mean , Low combustion energy.!!!
and that is:
1: spark bad, ?
2: fueling wrong to those 2. (injectors or vacuum leaks)
3: compression weak on those 2.?

the ECU measures the velocity of the crank shaft, (not speed) rate of velocity, and those codes, mean its slow.
too slow means its. weak combustion.
new plugs and coil. so....
i do compression first. just hate chasing my tail.
then check for no vacuum leaks near #3 and 6 (injector base gaskets)
then do a injector balance test with my pressure gauge.

the injectors can be clogged, , partial clogged or leak fuel.
they can leak air at the base.
i check plenum vacuum too for 19" Hg vacuum steady never bouncing. if it bounces head valves, bad, or ?

Crank position sensor should be in the area of the crank pully the largest pully on the front of the motor held in by one 10mm bolt The fuel tank pressure sensor can be bought separate but usually comes with a new fuel pump so the sensor is on top of the fuel pump exterior of the tank

The 2002 Santa Fe came with three (3) possible powertrains (engines). The 4 cylinder, and two different V6 engines - i.e. 2.4L 4 cylinder, the 2.7L V6 and the 3.5L V6.

The crankshaft position sensor on the 4 cylinder and the 3.5L V6 are in the same place - Front Crank Shaft behind the pully (behind the timing belt cover.

On the 2.7L V6, the Cranshaft Position Sensor is located in the engine block (Left Hand Side)
near the flywheel (adjacent to the LH (Bank 2) exhaust manifold.

Note: Left Hand Side means the radiator side (front) Bank 1 is the firewall side.

If my crankshaft cencer a & b are bad what would be the car be acting like. It has a 3.5 liter v6 in it.

Bad Idle, stalling, and engine in worst case will not start. The ECM take readings from the crankshaft and camshaft sensor to determine the engine's ignition timing and fuel injector timing.
A total sensor failure will cause the engine not to restart if there is no output reading form the sensor to the ECM. If there is an Auto Zone in your area, they can scan your car to address the issue if your crank/cam shaft sensor has gone bad and will need to be replaced.
Thank you for using fixya and Auto Zone scan free of charge and has the step by step instructions to get the job done.

you could have a bad crank sensor , I believe its located on the belhousing of the transmission. If you have alocal garage with a scanner that gives live data they possibly could record the signal while driving and record it.Good luck

My problem was the same. It was diagnosed as needing a new Crank-shaft Sensor. Replaced it and it ran great. Very difficult to get to physically!
