there are two of them one is one the header if front of the engine behind the radiator the other is on the top side of the catalytic convertor this is the one that usually goes bad it is like a spark plug with wires on it un plug the wires then unscrew the sensor put in the new one and plug it up

the O2 Sensor Should be on top of your exhaust manifold

9 time out of 10, the heater circuit internal to the sensor has failed. Replace the sensor.

The oxygen sensor is usually located on the exhaust system. You should find it just after the exhaust manifold and just ahead of the ctalytic converter...Don the Juan.

The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter

Use a 7/8" O2S wrench, socket, or crow's foot to unscrew the sensor, then put a new one in.

To change an O2 sensor you need to disconnect the wiring harness from the sensor. Use an O2 sensor socket and ratchet set to remove the old sensor and replace with the new one.

Remove the vacuum hose from the O2 sensor. Remove the wiring harness. Remove the O2 sensor retaining screws. Reverse the process to install the new O2 sensor.

Downstream O2 sensor is an O2 sensor after the catalytic converter. Upstream O2 sensor is an O2 sensor before the catalytic converter.

The O2 sensor provides necesary information to the computer. If the vehicle is burning too much fuel there will be insufficient O2 in the exhaust. If there is too MUCH O2 in the exhaust there is a possibility that the vehicle is not performing properly and also the possibility that you will burn valves, although your EGR valve should prevent that. Periodic replacement of your O2 sensor is just good maintenance and helps with good fuel economy.

usually bank 1 is the bank with # 1 cylinder in it and sensor # 1 is the front o2 sensor(usually in the manifold). You will need a O2 sensor socket or a 22mm wrench or deep socket.
