i honestly have never seen a knock sensor go bad. a knock sensor detects spark knock,which is from low octane gas. if it hears this then the ecm retards the timing to stop the knock. you wont be able to hear the knock that its listening for. its like a little microphone stuck in the block. before you replace it you might want to check the plugs on the sensor itself. if they are corroded they could cause this problem.. ANYTIME you have engine codes ,always check your ground cables on the engine and the battery. i work in the marine industry and you would be amazed all the codes you can get just from having a corroded battery cable..like i said , i have never seen a knock sensor go bad..

Above is the sensor itself on an 03 Avalon.
If the heater circuit has no activity check the relay located inside the engine room junction box JB shown below.

If single exhaust pipe, look for the bank 1 sensor 2 oxygen sensor to be either stuck into the side of the catalytic converter or just downstream of it.
If dual exhaust pipes, look for the bank 1 sensor 2 oxygen sensor to be just downstream of the catalytic converter for the bank of cylinders that contain cylinder 1.

what is the resistance of the wires between sensor and ecm connector, excess resistance from varying gauge wire and solder or solder-less connections can cause problems
