Bank 1 sensor 2 were is location of oxygen sensor on 1996 grand am 4 cylinder?
That would be the sensor after the catalytic convertor.
If it is anything like the '96 Grand Am, it is located under a cover between the engine and firewall. The cover has 3 bolts in it. Remove the bolts and the cover and you will find the O2 sensor (front - the other is just after the catalytic converter.) You will need a 7/8" wrench to remove the part.
There are two O2 sensors on a 2005 Grand Caravan and are located as follows: On 2.4 L four-cylinder engines, the upstream oxygen sensor is located on top of the exhaust manifold, above the flange. On 3.3L/3.8L V6 engines, the upstream sensor is located on top of the rear exhaust manifold, above the flange. The downstream oxygen sensor is located on the side of the catalytic converter on all models.
