2001 accent - knock sensor
 

Even though my car is running great,
the check engine light came on and the code indicated a bad knock sensor
(1.5 liter engine). Does anyone know how much this would cost?? Would it
be easy to do it myself???

It's not too bad if you can get under the car well. It bolts on the back
of the block with a 12mm head bolt. Cost will vary greatly by where you
have it done.

Thanks for the info. Is there just one knock sensor or two??

Just one. I believe the block location is the #2 cylinder.
