Volvo 940 location of Bosch O2 sensor not found in front of catalytic converter on Volvo 940

Some Volvo 940 owners report experiencing difficulties locating the Bosch O2 sensor, which is typically situated in front of the catalytic converter. However, some owners find that due to aftermarket modifications or specific vehicle configurations, the sensor may be positioned differently than expected. This deviation can be attributed to changes made by previous owners or unique specifications of the vehicle. If the Bosch O2 sensor is not found in its usual location, it may be necessary to investigate alternative placements based on the individual circumstances of the Volvo 940.
