damper position to the air
conditioning amplifier. The air conditioning amplifier activates the motor
(normal or reverse) based on
these signals to move the air inlet control damper to the appropriate pos ...
Catalyst system efficiency below threshold (bank 1)
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 ...
