I have been driving my car for a while now and I've started to notice that when I step on the gas pedal the car kind of hesitates. After a quick obd scan the scanner tells me it's the knock sensor. Anyone now the procedure to remove the knock sensor? Thanks.

 

There are two knock sensors mounted on the front of the block. Never had to replace a pair. You might want to diagnose your problem rather than simply replacing parts that you think are bad. A knock sensor code does not mean the sensor is bad - it means the control unit does not like the signal from it. Here's a list of knock sensor codes that VIDA has, and for one of them (ecm3410) a list of possible causes. Note "worn engine" is a possibility and the Fault symptom is "NONE". In other words the knock sensor does not change the way the car runs, at least in a perceptible way. Next picture - note that a code 3400 could indicate a problem with the ECM.
