Code 43 question....

OK, got a question. Are there an other sensors or modules that could cause Code 43 in an OBD1 car? I have already eliminated the KM, ICM, and have a new KS on order, are there any others while I am at it?

I just had the code 43 several weeks ago. It was a bad knock sensor. Solved all my problems.

Check for 5volts at the sensor wire with the key on. Then check the resistance of the the knock sensor terminal to the engine block, it should be between 3.3K - 4.?K ohms.
