GF07.04-P-6100V O2 Sensors, Component Description
O2 sensors upstream TWC, location
The O2 sensors upstream TWC are bolted into the exhaust pipe upstream of the catalytic convertors.
Task of the O2 sensors upstream TWC
The O2 sensors upstream TWC (control sensors) are designed as wideband oxygen sensors and detect the residual oxygen content in the exhaust gas for
the following tasks:
-
Lambda control
-
Self-adaptation of mixture formation
-
Function chain tests.
