Are you sure that you need to replace the knock sensor. I have a 1996 G-20. It had 3 check engine codes. #1 was knock sensor, #2 was Egr valve, #3 was O2 sensor. I performed some testing and then replaced the EGR and canister control solenoid. It is located on the back side of the engine and is somewhat accessible from below. After it was replaced all 3 codes cleared within one week. A new unit was $100 from the dealer. It is possible to repair the old one if you are technically and financially inclined. step 1 test egr valve and the vacuum valve attached to it. step 2 remove the Egr and canister control solenoid valve. Test it by blowing air through it and then applying 12 volts to the solenoid. If the air flow does not change it is stuck. Replace or repair it.
i need to locate knock sensor on a 2000 infiniti g20
How to replace starter on a 95 G20 infiniti?
in the distributor
The 1994 infiniti G20 does not have a timing belt, thus you can't replace it even if you want to. The G20 has a timing chain and does not need changing ever!

Remove the vacuum hose from the sensor. Pull the sensor out of the air cleaner housing. Insert the new sensor into the air cleaner housing and attach the vacuum hose.
