Your cart is empty. A knock sensor is located on the intake manifold, cylinder, or engine block. The purpose of the knock sensor is to sense unusual pulsations caused by the engine knock or detonation.
Symptoms of a bad knock sensor are check engine light CEL on, loud sounds, bad fuel mileage, poor acceleration and poor engine performance.
When you replace the knock sensor please be careful the grime will fall into the cylinders when you pull the intake manifold off.

Shipping was quick, Part for 2014 sante fe sport fit correctly, after 4 hours of removing the intake to install the new part it didn't resolve the flashing check engine light or the lack of power.Knock sensor was diagnosed by dealer, thus why I replaced it.Update, you must have the computer cleared of codes after the installation.After the codes were cleared it did work and all is back to normal
