WHERE TO I FIND MY KNOCK SENSOR TO REPLACE IT.

2003 Hyundai XG350 • 130,000 miles

I went to pepboys because I engine light came on. That was a day after I went to that same store to get my car inspected for the state of new york. That day all I needed for two back brakes and I was all set to pass my inspection.

However the following day I was told I had two problems. My throttle position sensor needed to be replaced and my knock sensor needed to be replaced. I have already replaced the TPS although the check engine light is yet to come on, there is still a delay in the car transitioning from one gear to the next while in 'D'.

Basically there is a delay. So I would like to replace the knock sensor to see if that will eliminate my problem.

Okay. Thanks a million for the urgent reply. But it seems like I am blinding looking because I can't seem. To find it. The diagram suggests that its on the same side as the fan belt.

If that's where it is how do I go about taking it out

Okay Thanks I will look at it in the morning. What I have also noticed is that after I change the TPS and reconnected the battery will am driving the car heat is coming through the vents even when I have the ac/heater off.

The heat shuts off when I turn the ac on, then it get cool and then I would turn off the ac then the heat will stop coming through the vents

O.K. Vehicle is a XG 350L so V6 not 4 cyl so Knock sensor is top of engine follow radiator hose to engine sensor is intake between hose and cover. Have codes rechecked before cause knock sensor not going to effect shifting
