Bank 1 is the side where #1 cylinder is. Unfortunately it is the one at the back by the firewall.
Sensor one is the one just before the pre-cat (actually it is just in the front of it). It monitors air/fuel ratio just before the exhaust goes in to the pre-cat. Sensor 2 would be the one on the far side of the pre-cat as sensor 2 monitors the exhaust after it goes thru the pre-cat. http://www.justanswer.com/uploads/eb...-29_124239.png THE FOLLOWING IS A PIC I TOOK OF THE FRONT ONE ---- SENSOR CLOSEST TO YOU IS SENSOR 1 http://i1049.photobucket.com/albums/...Pre-CatO2s.jpg http://i1049.photobucket.com/albums/...J/SAM_2174.jpg The sensor you want is the one in the exhaust pipe of the engine cylinder bank that has #1 cylinder in it, as you face the engine with the hood open the cylinder bank u want is the rear bank, u will need to jack the car up and get under it to remove the sensor, u may also need a special socket to remove it, the sensor is the one that is before the catalytic converter. part number is: DENSO Part # 2344068 REAR; Before Catalyst |
