It depends on which sensor, O2/camshaft,etc. The O2 sensor is a straight metal sensor that is screwed into the exhaust. There is an upstream/bank1-sensor1 or down stream/bank1-sensor2 after the catalytic converter. A camshaft sensor is an L shaped, usually black sensor that is installed into the head closest to the firewall(bank1).
