Where to i find my knock sensor to replace it.

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
