To replace the O2 sensor in a Volvo S70, first, ensure the engine is cool and disconnect the negative battery terminal. Locate the O2 sensor, which is typically found on the exhaust manifold or in the exhaust pipe. Use a socket wrench to unscrew the old sensor, then install the new sensor by threading it in and tightening it securely. Finally, reconnect the battery terminal and clear any error codes if necessary.
Upstream O2 sensor is located on the first muffler pipe coming out of the engine. This sensor can be found after you open the whood and look directly behind the engine. The sensor is connected to a wire and will end on electric connection to your computer.
To replace the O2 sensor on a 1993 Volvo 240, first, locate the sensor, which is typically found on the exhaust manifold or downpipe. Disconnect the electrical connector and use an O2 sensor socket or wrench to unscrew the old sensor. Install the new sensor by threading it into the same location, tightening it securely, and then reconnecting the electrical connector. Finally, start the engine and check for any error codes or issues.
All this work is done from under the car. There are two sensors on the S70. One is called the upstream( located higher up on the exhaust manifold) and the other would be the downstream. They are located on the exhaust pipe prior to the cat. converter. Unscrew the sensor (need to borrow a special tool) and follow the wire up around the engine to a small connector. Be sure to use anti-seize grease around the threads of the new O2 sensor(s). rcal13a@yahoo.com

Yes, a 1989 Volvo 740 can run without an O2 sensor, but it may not perform optimally. The absence of the O2 sensor can lead to increased fuel consumption and higher emissions, as the engine management system relies on it to adjust the air-fuel mixture. Additionally, you may experience rough idling or decreased engine performance. It's advisable to replace or fix the sensor for better efficiency and compliance with emission regulations.
