Can't find the sensors? 900

I have a 91 740 so I assume yours is similiar. O2 sensor is in the exhaust line near the cat. Look for a large spark plug looking device with a wire that runs up to a connection on the firewall. Knock sensor is bolted to the block under about intake runner #2. The temp sensor is right beside it on the left. You can find photos in the FAQ. THe AM sensor if I understand what you're asking is in the large bellows like hose that runs from the air cleaner to the throttle body. I think it is the air temperature sensor in newer cars.
