When cleared, the CEL will turn off until a steep grade or other means of heavy acceleration.
I read about splicing the two sensors together to trick the ECU around the code and that this worked for many people - thinking this would be the best step since it was the least amount of work and money, I gave it a shot but to no avail. CEL still on.
Next weekend I'm just going to replace the sensors and harness together and call it good; you might as well if you have to open everything up just to service either one. Knock sensors are a headache that will NOT go away like other codes.

I feel ya. It's a stubborn code that's a lot of work and money to fix and becoming more frequent. I fear this code is going to put a lot of 4Runners out of commission due to the high repair costs vs value of the vehicle.
