will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen sto ...
P0172 fuel injection system function
DTC Description
DTC DETECTION LOGIC
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture
ratio can be brought closely to the
theoretical mixture ratio based on the mixture ratio feedback signal from the
A/F sensors 1. The ECM calculates
the necessary compensation to corr ...
