Where whould I find the knock sensor or sender??? what else could it be?? any ideas. need to try to fix it by the time snow hits.
I think the bottom end is pooped in it so I'm getting another one but I would like to get rid of the light.
it turns on after like 2 mins of driving, when its at idle its fine once you move thats when it turns on.

On the 22R-E the knock sensor wire harness is located behind the oil filter,check the wire harness inside the passenger side going into the ECU.
About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes to see if a fault is registered.
To pull the ECU codes:
All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

Pulling the ECU codes is the first thing I do to diagnosis a problem thereafter I reset the ECU to see if the same problems show up and if so I then take voltage measurements both with the engine running and not and compare with the factory service manual,I also close the ignition switch after a cold engine and also after a warm engine and compare them with the factory service manual.This technique will completely isolate your problem without having to do trial and error and it is the technique I use when repairing tv's,vcr's,home/car audio.
