Its in the middle of the block and an inch or two down from where the head meets the block. Alternately, You can follow the wire to it, which is clipped in the corner space between the valve cover and the intake manifold (on the passenger's side of the intake manifold and towards the firewall from the valve cover). It should be the only wire on the side leading to the block.
i been working on cars 20 years i haven't seen a knock sensor make a car miss it;s job is to ajust timing i have seen it set off service lights why would you think it's a knock sensor if i knew more infoe i might be able to help you
the price of the 02 sensor. under 20 bucks. and about 10 min of your time.
The knock sensor is located on the bottom of the block just above the oil pan rail. It is either on the driver or passenger side depending on motor size, and is about 1/2 way from the front of the block.
just below the engine oil dip stick. It has and octagonal shape
You have to especify wich sensor, a cooooomun caor has around 20 different sensors, ( TPS, AIR FLOW METER, Knock sensor, air bags sensors, coolant temperature sensor, etc.) WICH one. HA HA HA HA reddragon
The O2 Sensor on my 92 G20 with a 4.3L is on the left header tube on the top, right next to the transmission. its a 3 wire 02 Sensor....hope this help, I just need to know what size open ended wrench to use...i think its a 16mm
You need to purchase the tool for removing the O2 sensor. It's a socket that has a slit down the side for the O2 sensor cable. This will cost you about 20-30$. The 02 sensor will un-screw with a socket wrench. Best done when car is cold. Otherwise you will burn your hands. Good luck.

Code 43 is a knock sensor (ESC system fault). If you have a hard 'check engine' light, try this. Disconnect the negative terminal on the battery for a couple of minutes, then reconnect. Start vehicle. If the 'check engine' light comes on within 15-20 seconds or so, chances are either the connection to the sensor is poor, or the sensor is bad (open). Shut off car, then disconnect the connector to the knock sensor. Read the voltage to the connector pigtail (key on engine off). It should be 5 volts. Then ohm check the socket on the sensor itself (to ground); it should be 3.9k (depending on knock sensor used). Run a jumper between the pigtail and the sensor, making sure you have good and solid contact to both. Key on, engine off, the voltage at the connector should now be 2.5 volts. LEAVE THE JUMPER IN PLACE. Disconnect the battery neg terminal again, for a couple of minutes (to clear the code). Reconnect neg battery terminal and with the jumper between the connector and the knock sensor still in place, start the car. If no 'check engine' light within 20-30 seconds, let car continue to run for a few minutes. If still no light, it's the connector that is bad. It could be the pigtail, or the sensor connector itself. I repaired mine without changing the sensor.
