P0130 A/F SENSOR 1
P0130 A/F SENSOR 1
DescriptionINFOID:0000000005398360
The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sen-
sor. The sensor element of the
A/F sensor 1 is composed an elec-
trode layer, which transports ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range.
The exhaust gas components diffuse through the diffusion layer at
the sensor cell. An electrode layer is applied voltage, and this current
relative oxygen density in lean. Also this current relative hydrocar-
bon density in rich.
Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this
electrode layer of current. In additi on, a heater is integrated in the
sensor to ensure the required operating temperature of about 800° C
(1,472° F).
DTC LogicINFOID:0000000005398361
DTC DETECTION LOGIC
To judge the malfunction, the diagnosis checks that t he A/F signal computed by ECM from the A/F sensor 1
signal fluctuates according to fuel feedback control.
