This is a very common problem with the Snate Fe. It is a scam so they can charge you $350 to replace a defective sensor. They know the sensors are defective and don't last long but it is a money maker so they have not done anything about it.

SOURCE: check engine light on rpm gauge
ok the crank sensor controls the rpm gage on your vehicle it sends a signal from the crank sensor to the pcm computer and from the computer to the rpm gage, there are 2 possible causes and that is the crank sensor not sending a signal to the instrument panel due to shorted, or the pcm not sending the signal to the instrument panel due to also shorted, there is a way to identify what the problem is.you will need to get the codes stored on the pcm memory with a scanner , or start by replacing the crank sensor , located on the transmission bell housing.------------ As you mentioned that check engine light is ON.So did you got the computer scanned.------In scanning you will get codes and as per codes replace the faulty part.---------
At autozone service center its absolutely free to get car scanned.They do it for free.------------ One more thing you can try is try to reset the computer and see, if check engine light turns off.--------- Disconnect the negative terminal of car battery for 30 minutes, then clean the terminal and reconnect it and turn the car on and check.If the check engine is off, that means reset is complete.But if still the check engine light is ON.Then the car needs to be scanned.---------- This will help.Thanks.Helpmech.

You stated the 'CHECK ENGINE' light came 'ON'!... what/which DTC'S (Diagnostic Trouble Codes) OBDI were retrieved? In 1991, OBDI (1) was used. You could retrieve codes by either turning the ignition switch on/off two or three time within 3 seconds and the light would flash for each number (this way you could determine which system was affected). The POSSIBLE CAUSES are many:
Crank Position Sensor
Electrical (Relay(s), fuse(s), Poor ground connections, failed ECU (Engine Control Unit), etc.
Are you getting a SPARK to the plugs?... if so, check fuel pump pressure
If you're not getting a spark to the plugs or not getting a fuel injector PULSE, then the crank position sensor MIGHT BE the problem.... NOT SURE!
Too many POSSIBLE or PROBABLE causes.
In order for an engine to RUN, it needs these things:
1. Air flow (intake AND exhaust)
2. Fuel (proper fuel to air mixture)
3. Compression (140 to 2?? psi)
4. Proper Timing (not too advanced/retarded)
5. Ignition (sufficient and at the correct/right time)
Now, after listing these 5 things, without CHECKING each one, your guess is a good as mine.
