Rear Heated Oxygen Sensor (HO2S)

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

The rear heated oxygen sensor (HO2S) operates with the same signal characteristics as previously, but has gained more importance for controlling the fuel/air mixture. The rear heated oxygen sensor (HO2S) has been moved forward nearer to the front heated oxygen sensor (HO2S), just in front of the metal monolith in the catalytic converter.
