The oxygen sensor is located on the upper portion of the exhaust manifold near the back bank of cylinders on your van. A special socket is required to remove it without damage. Go to the Related Link for more information.
it is the upper stream o2 sensor before the convertor
It"s located on the rear manifold, between the firewall and the engine for the upper oxygen sensor(b1s1), and between the catalyst converter and the resonator for the second oxygen sensor (b1s2), between the pipe and the floor.
All oxygen sensors on all vehicles are on either the exhaust manifold or the upper end of the head-pipe.
the sensor is under the upper intake.it is easier to remove upper intake then look to your right in back of lower intake
the o2 sensor is located at the left side of the engine towards radiator and is the upper o2.
get the truck up on some ramps. Just behind where the two exhaust pipes "Y" together, you'll see it.Screws in from the upper side (near the floorboard) down.
Just unscrew it and replace the wiring. The upper oxygen sensor is on the exhaust manifold, close to the headpipe. The replacement sensors are often plug compatible, but others must be spliced in to the old wiring. If you end up with that, refer to the instruction to figure out where the wires go.
There is a slot on the upper side of the sensor. Just put a screw driver in it and and pull up and it should slide out.
The 1996 GTP has two oxygen sensors one upper, one lower, the upper is on the down pipe (just below the crossover from the exhaust manifolds (not easy to reach) Try from below.-be careful. the other oxygen sensor is about half way down the exhaust pipe, close to the catalytic converter. The bank one sensor is probably the cam timing sensor, it is on the front bank cam carrier close to the thermostat housing.(on the cam carrier.) You will need a special socket to remove the oxygen sensors- don't damage the pig tail during installation and don't touch the tip-you may screw up the readings. Good luck.
Bank 1 is the upper oxygen sensor(s) before the catalyst (catalytic converter) bank 2 is the oxygen sensor after the catalyst (catalytic converter)
