knock sensor replacement
My "Check engine light" indicates I need to replace a knock sensor. How many "Knock sensors" does a SVX have?

Re: knock sensor replacement
Two. The code should tell you which one is bad if I remember correctly.
Edit: 22 = right side, 28 = left side

Re: knock sensor replacement
Thanks for the info. I didn't pay attention after my mechanic said "knock sensor" so I don't know if he told me which side. I found a site on ebay which sells them for under $6 including shipping (not from China but Florida so I don't know about the effect of Irma),so I'll just order 2. Thanks again.

Re: knock sensor replacement
I checked Rockauto and their cheapest knock sensor is about $30 while these from FL. are under $6 but I need to check if they are made in China (my guess is YES) but I need to wait until after IRMA destroys FL. to try and contact the seller.The photos are a great help since I didn't know where the knock sensors are located but it looks difficult to reach those sensors, even w/proper tools since I don't have small hands.

Re: knock sensor replacement
After looking at those instructional photos, I ask why are the knock sensors so hided; guess the designers aren't mechanics.

Re: knock sensor replacement
To do their job, they have to be on the block to sense the "Knock" in the motor, to keep timing in check....

Re: knock sensor replacement
I replaced mine. It was a piece of cake! Especially since I already had the intake manifold off...

Re: knock sensor replacement
I didn't mean to insult an engine designer but I realize they have to be in the block to do their job. Since I really don't know how they measure knock in all 6 cylinders from the center cylinders on each side, their placement could be in a more convenient location since they will eventually need to be replaced. As far as the replacement knock sensors for < $6, they are from China, not my first choice of manufacturing. I'll check w/Rockauto but they may also be from China.

Re: knock sensor replacement
Hmm. I didn't find it very difficult to just slip in the box wrench & change the sensor without disassembling everything. (Passenger side)
