Ok so I got that code 52 last week and just ordered the ATS GM knock sensor kit over the weekend. Now today i just read somewhere on mr2oc that all the GM sensor does is "ignore knock" because it vibrates at a different frequency than the stock toyota one.
What do you guys make of this? I dont want to run the risk of damaging my engine because i'm getting undetected knock. did i just waste my money on the "more durable" ATS GM sensor? |

this is one thing that kinda worries me about the GM knock sensor mod:
your knock sensor is, in very basic terms, a microphone, tuned to a specific frequency. the gm knock sensor is tuned to 5.8khz, and the 3SGTE one is tuned to 6.6khz. while they may be close, they ARE diffrent. exactly how much this effects the knock systems response is somthing i dont have the answer to, unfortunatley..lol heres a copy past from somthing i found with a quick google search: the gm sensor listens at 5.8 khz and has a non resonant pulse at a higher amplitude as opposed to 6.6khz for the toyota which has a lower amplitude sine wave i had one on my car rev3 turbo and had holdiong back issues switgched to to the oem and was fine -------------------- Former Team 5SFTE pro member ;)
