O2 Sensors before cat
The O2 sensors upstream of TWC are bolted into the exhaust pipe upstream of firewall catalytic converter.
Task
The O2 sensors upstream of TWC (control sensors) detect the residual oxygen content in exhaust gas for the following tasks:
-
Lambda control
-
Self-adjustment of mixture formation
-
Function chain tests
The O2 sensors upstream of TWC are insulated as voltage free and designed as a planar (flat) wideband oxygen sensors.
The active sensor ceramic consists of a gas permeable ceramic body made of zirconium dioxide. The inner protective tube with several slots protects the
