Hate to add another thread of car problems. Was in a rush this weekend and needed to get the car running. Ran to my local oriellys and got 2 knock sensors since i was running on the knock sensor hack for almost 2 years. My other knock sensor i guess crapped out finally and got both knock sensor codes. Took off the intake manifold and replaced the sensors and i got the check engine light again, i also got a an 02/cat code along with the knock sensor codes.
Any idea why i would get an 02 code the exact same time the knock sensor code pulls up? Or would that be a coincidence? I just read after the knock sensor code came up that our cars dont do well with aftermarket sensors in general, u think thats my problem? Has anyone changed any of the knock sensors out with aftermarket with success? I am only getting the code for 1 bank. I need to get this resolved cause i am drivong around with a obd2 scanner to clear the codes whenever i get the check engine light
The one other thing i noticed that really bothers me is that the inside of intake manifold looks like it is sludged up with oil. It is completely black... Could i use throtte/carb cleaner to clean it and run it on some seafoam to get more inside near the cylinders? Hard to see in the pic but if you look closesly it is black

Any knock sensor will not work, do you have a pic of the Sensors? Make?
Whats the knock sensor hack? Dont tell me you bypassed the knock... 2 years? Really man? are people really treating these cars like ghetto trash? SIghhhh
Yes, you can use carb cleaner to clean the Mani. Whats all the Crazy Audio Cable wires running to your engine? Dont tell me its BIG 3? I wouldnt be surprise if your having Parasitic Draw or electrical/charging issues.. Lol
Rock auto has some good aftermarket knocks that will work if you cant afford OEM.

i dont have pictures of the sensors i will have to check when i get home and i can post up pictures, but if i had to guess it would be import direct since that is whats showing up on the oriellys website. Yes i will admit, i did the bypass and i completely forgot about it, however i dont daily the car as much and has been sitting in the garage for a while. And yes that is my big 3. Also Can you point out your reason for thinking that i am having a parasitic draw? Cause i dont seem to have any charging or electrical issues.
Other than that.. Have fun trying to figure out authenticity of the Number of Fake sensors that have FLOODED the market due to people trying to Ghetto rig their cars.. Supply and Demand
Knock sensor , did you change the knock sensor wire ,the pig tail? Most likely thats your problem and not the knock sensors. I would do much cleaning of the intake system on the vehicle. Remov it completely. Do not clean your cylinders. Change the wires and reinstall your knock sensors. Note do not over torque the then they will be bad.

2GS doesn't have a separate harness to replace for the knock sensors.
Just check the wires. I didn't see any damage to my wires but I completely wrapped them with electrical tape anyway. Also just make sure the connectors fit snug. I would say the problem is definitely the aftermarket sensors. Just get the ones from the link I gave you and you will be fine.
You wouldnt see the damage, is wire hard or brittle? You should have not wrap it either. Those wires are sheilded and once you wrap it and its hard or brittle the insulation would crack up and would loose the signal to the computer. You could get the wire separately.its the same as the toyota sequoia.

I just did a LS 430 and here is what my symptoms were. Check engine light for bank one knock sensor 325. I use to work for Lexus and have done them before. Most the time it’s your pig tail wire that connects to your knock sensor.
You don’t have to drain you coolant. Make sure you buy two new sensors and pigtails because there is no harness that you can buy the harness you see on the internet is wrong just use the pigtails from the harness here is link got two sensors denso brand and wiring harness for 30.00 https://m.ebay.com/itm/OEM-Knock-Sen...anner=1&_rdt=1 I took a gamble to see if it was to good to be true but it’s good no check engine light after I drove it for 3 days nothing yet. Make sure you get o rings for the fuel injectors if you have over 150k on the car you will need them. Any questions ask me I can help on misfiring evap codes you name it

hey did the check light come on yet ? I was just looking at these dense sensor
Looks like the issue is figured out. I just wanted to put my .02. As a tech I see more wiring issues than bad knock sensors. For any Knock sensors that you have to pull the intake to access, its always a good idea to change the pigtail. Or at least us a DMM or some form of Ohm reader to check for continuity between the connector pins and somewhere accessible from outside the manifold. As long as you show continuity from outside the intake to the connector ends, you'll be able to get away with just new sensor(s).

aftermarket knock sensor problems, + intake manifold cleaning
