Should be on the front of the engine block, if you have a vortec it is on the lower maifold below the EGR valve.
code 43 is related to the spark control system. (esc) the problem is usually the knock sensor wiring connector is defective and/or the sensor. the sensor is located in the right /passenger side of the engine block near the starter.

Got it - cracked Engine Coolant Temp sensor for computer - guess I was tired when I first looked and missed it on the scan tool, (I was sick the day before and stayed home from work) it was showing -1 to 5 degrees when the car had been sitting for 24 hours and intake air temp was 43 degrees. Replaced the sensor and did a tune up, all is great again.
there isn't one.

Electronic spark control is not receiving sinal from knock sensor Try replacing knock sensor
Code 43 indicates a fault in the ESC (electronic spark control) system. It usually means the knock sensor has failed, or the wiring to the knock sensor is faulty. When this fails it causes the computer to retard the spark timing to protect the engine, resulting in stalling, poor performance and reduced mileage.
