2000 Sonata stoping problem

Hello!

I have a question about my 2000 6 cyl Sonata. At the light the car
stopped (the AC was on) and the check engine light came on. I managed
to start the car (CEL did not come on), drove into the parking lot and
tried to recreate the problem but could not. I hooked up the ODBII
reader and got the following codes:
0335 - crankshaft position sensor A circuit
1372 - ?

What does this all mean? Car stoppage at the light is happenning for a
while now.

Your response is greatly appreciated

 

Both of these are codes for the crank sensor. I've not seen these codes on
this engine caused by anything other than the sensor itself. Replace the
sensor and all should be well. It bolts into the block behind the
starter. For the DIYer, it's probably easiest to remove the starter and
then unbolt the sensor and pull it out.

 

Thanks, I hoped you would answer, you are the man!

What is interesting that when I read the codes, the the check engine
light was not on!
How is it possible that those codes were raised without the lights on?
Also how does this
sensor relate to the engine stopping?

 

Most failures on OBD-II compliant vehicles won't set the "Check Engine"
lamp until they happen once each in two consecutive drive cycles.

This sensor relates the crankshaft position and speed to your ECM.
Without this information, it doesn't know which plug/injector to fire or
when. As far as your ECM knows, when there's no readout from the sensor,
the engine is not turning.

 

Thanks, you were extremely helpful!

 

Sorry, one last thing. Does the vehicle have to be elevated to remove
the starter or it can be done from the top?

 

You'll need to take it out from underneath. Be sure you disconnect the
negative battery terminal to prevent nasty arcing/welding flashy things.

 

Thanks again, I will have to go to the dealer, he quoted $150 for the
replacement. Seems an OK price.
