Hey everyone. My TL-S has been throwing this P0325 code for quite a while now, and I just can’t seem to figure out what the issue is. I replaced the knock sensor once, and the code came back after driving it on the highway for a bit. I then replaced the sensor (again) and the wiring harness, yet the code popped up once again.

After replacing the sensor + harness the second time, my mechanic was quite puzzled too, and said that the only thing he thinks it could be is an ECU issue. I don’t mind getting this replaced, but I’d just like to cover my bases first to see if it’s something more minor. Anything else you guys think I should check? The car still drives fine, although I don’t think it’s accelerating quite as fast as it normally would. The car only had 126k kms too.

pics attached of the car just to hopefully bring attention to this thread. Thanks. 🙏

 

Whooops, seem to have attached a pic of my homework as well by accident lol. My bad.

One thing I forgot to mention, when I got it replaced the second time my mechanic hooked it up to his scanner and showed me that the sensor was in fact functioning, but it seemed to be overcompensating due to the misfire. As in it was retarding the timing every time I accelerate.

 

I'v removed the photo for ya!

Have you done any other work on the car like spark plugs, coils, etc?

 

Ever solve this one? I'm having similar issues...
