I think they often route wires along side the steering column and/or other holes in the firewall such as for gas peddle/throttle cables, heater hoses, etc.

Some vehicles have a fuel cap pressure censer in the computer this will sometimes cause the engine lite to come on. Make sure to tighten the fuel cap all the way. You might try replacing the fuel cap.

THE DEALER

Try replacing you blower resistor. Usually they short out one speed at a time

change your spark plugs..all of them...and and put in the correct amount of oil..

Sounds like a lean miss check your fuel filter for restriction Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/craig_a14a43e01fd0835a

may have wrong fuel did you put diesel in by mistake ? may have water in the fuel put some mentholated spirits in fuel tank if water in it.

when working on the vehicle it is easier to remove engine and transmission as an assembly

If it hasnt been done already, it's a good place to start. Be careful to release pressure before removing it!

the engine has a timing chain so the noise will be loose chain slapping around time to replace the chain

you have speed sensors and tone wheels on all the axles so I'm thinking that you have some cracked tone wheels on the axles that set codes in the PCM

crankshaft position sensor faulty...works until it gets hot then shuts down entire engine until it cools. replace the sensor.

This is a manufacturer specific code and does NOT mean traction control prime valve. You can just look online for the definitions of manufacturer specific codes because each manufacturer can define it however they want. C1274 for a 2001 Hyundai Sante Fe is G-sensor signal fail. It measure "G" forces to determine if you need 2WD or 4WD. Start by checking the fuse for the G sensor. Fuse 23 in the passenger compartment fuse box.

Possibly the fuel filter may be clogged. I’m leaning more toward a vacuum leak, or ignition coil(s) could be failing. Local parts stores can & will read for any codes usually for free. But Hyundai is known to have shorts in ignition system. That would have to be traced & found to be repaired. There is no code for that, so you might end up buying parts you don’t need before finally realizing it was just a bad wire or connection!

replace switch

You might try testing the tps. It may have a dead spot at the high end of the throttle opening. Make sure the resistance continues to change as you open the throttle all the way.

Throttle Position Sensor

Operation The throttle position sensor is a rotating type variable resistor that rotates with the throttle body-s throttle shaft to sense the throttle valve angle. As the throttle shaft rotates, the throttle angle of the sensor changes and the ECM/PCM detects the throttle valve opening based on the TPS output voltage. Removal & Installation

1. Disconnect the negative battery cable.
2. Disconnect the sensor connector.
3. Remove the sensor retaining screws. Remove the sensor from its mounting.

To install:

1. Installation is the reverse of the removal procedure.

Testing 2.4L Engine

1. Disconnect the sensor connector.
2. Measure the resistance between terminal 1 (sensor ground) and terminal 2 (sensor power).
3. Specification should be 3.5-6.5 kohm.
4. Connect and analog ohmmeter between terminal 1 (sensor ground) and terminal 3 (sensor output).
5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.

2.7L Engine

1. Disconnect the sensor connector.
2. Measure the resistance between terminal 2 (sensor ground) and terminal 1 (sensor power).
3. Specification should be 3.5-6.5 kohm.
4. Connect and analog ohmmeter between terminal 2 (sensor ground) and terminal 3 (sensor output).
5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.

1. Disconnect the sensor connector.
2. Measure the resistance between terminal 2 (sensor ground) and terminal 1 (sensor power).
3. Specification should be 1.6-2.4 kohm.
4. Connect and analog ohmmeter between terminal 2 (sensor ground) and terminal 3 (sensor output).
5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.

3.5L Engine

1. Disconnect the sensor connector.
2. Measure the resistance between terminal 3 (sensor ground) and terminal 1 (sensor power).
3. Specification should be 3.5-6.5 kohm.
4. Connect and analog ohmmeter between terminal 3 (sensor ground) and terminal 2 (sensor output).
5. Operate the throttle valve slowly from the idle position to the full open position, and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
6. If the resistance is out of specification, or fails to change smoothly, replace the sensor.

I think you should buy repair manual first for your vehicle after that it will be easy for you to solve the problem. Check the link may be you will find something useful here Hyundai Santa

Try disconnecting the battery for about 5 minutes.

look in plug bad or loose connection can cause this problem . check wiring going to other light
