GF07.04-P-6100KE Component Description Of The O2 Sensor
- up to model year 08
Component Identification
The O2 sensor upstream of the catalytic converter is located upstream of the firewall catalytic converter and the O2 sensor downstream of the catalytic
converter is located downstream of the firewall catalytic converter.
Task
The O2 detect the residual oxygen share in the exhaust and transmit corresponding voltage signals to the ME control unit (N3/10).
O2 sensor upstream of TWC (slave sensor):
^
Closed-loop mixture control
^
Self-adaptation of mixture formation
^
Function chain test
O2 sensor downstream of TWC (master sensor):
^
Two-sensor control
^
Monitoring of the catalytic converter effect
