EC-1120
[YD (WITH EURO-OBD)]
DTC P0130 A/F SENSOR 1
DTC P0130 A/F SENSOR 1 PFP:22693
Component Description BBS002J8
Air fuel ratio (A/F) sensor 1(1) is installed on the downstream of Oxi-
dation Catalyst with DPF. A/F sensor 1 measures the oxygen level in
the exhaust gas and converts it into a voltage signal. A/F sensor 1
sends the signal to ECM. Based on the signal from A/F sensor 1
ECM calculates the air fuel mixture ratio. ECM uses the calculated
ratio for the DPF regeneration control.
A heater is integrated in A/F sensor 1 to ensure the required operat-
ing temperature.
CONSULT-II Reference Value in Data Monitor Mode BBS002MA
Specification data are reference values.
On Board Diagnosis Logic BBS002J9
