2nd datapoint for this particular brand knock sensor.
My son's 2006 CVT Insight was getting a CEL and P0325, which kept disabling the IMAC&C (it just kept on displaying "P0325" and we couldn't do anything else with it). Time for a new knock sensor.
Majestic had it for 122.07 + 8.26 shipping = $130.33. Then I came upon joeaax1j's 2014 post about a cheaper part and thought "why not".
After contacting joeaax1j who confirmed that his 5-year old Advance Auto Parts knock sensor was still working, I ordered one. The part number is Intermotor S8830, $90.99. I was able to get a 25% off coupon (floating around somewhere) and free shipping, my final total with tax came to $72.76
The old one is on the left, new one on the right. While on the car, the green portion of old knock sensor was intact and in place. But it was brittle and soon split apart.
I finished installing the new knock sensor today. The CEL disappeared immediately and the IMAC&C is now operable again! I drove it for around 10 miles and CEL has not come back.
A BIG THANK YOU to joeaax1j for saving me $57.57!
I will update my post in the coming days should the P0325 CEL return.
