Monitor description
The ecm uses sensors mounted in front of and behind the three-way catalytic
converter (twc) to
monitor its efficiency.
The first sensor, the air-fuel ratio (a/f) sensor, sends pre-catalyst
information to the ecm. The second
sensor, the heated oxygen (ho2) sensor, se ...

Pressure sensor circuit
Description
This dtc is output when the refrigerant pressure is either extremely low
(0.19 Mpa [2.0 Kgf/cm2, 28 psi]
or less) or extremely high (3.14 Mpa [32.0 Kgf/cm2, 455 psi] or more). The air
conditioning pressure
sensor, which is installed on the pipe of the high pressure side, detec ...
