Answer 2

i depends on if its sensor and bank 1 or sensor and bank 2, sensor and bank 1 is in front of the catalytic converter whereas sensor and bank 2 are behind the catalytic converter. just look for the sensor sticking out of the exaust, disconnect and resolder wiring all you really need is a crescent and a soldering iron. i just went through this with my 2001 Mitsubishi eclipse spyder.

Answer 3

the o2 sensor is located in the exhaust system, protuding from the catalytic converter. to replace the sensor u need a sensor socket of the rite size (they usually all only come in one size). Its a socket with a slot cut out of it for the wires to fit by when loosening the sensor. Its prolly easier to remove the whole exhaust system out since its only held by elastic bands, but u can do it with it attached as well. Loosen sensor with sensor socket, remove and replace. Oh and one more thing, remember to do this when the car hasn't been started for at least an hour or two otherwise that exhaust will scold u bad.

To change the O2 sensor in a Volvo 240 DL, locate the sensor under the car near the exhaust manifold. Disconnect the electrical connector and use an O2 sensor socket to loosen and remove the sensor. Install the new sensor by tightening it to the proper torque specification and reconnecting the electrical connector.
