hey guys,
I just finished the rest of my exhaust the other day and my check engine light came back on even though i replaced all the o2 sensors ( i replaced all three because the ses gave me a o2 code). anyway i pull the code again and i get 0702 which is Three Way Catalyst (right bank). I have no clue as to what that means? So as usual i need help wit this, cause i have absolutly no clue as to wat it means.
Thanks,
Will

 

anyone have any info on this?

 

0702
Diagnostic Trouble Code 0702 points to a problem with the three-way Catalytic Converter.

The Cat is one of the principal components of the emissions control system. The Engine Control Module monitors the signals from the two front Oxygen Sensors and the one rear Oxygen Sensor. The signal frequency of each sensor indicates something about the condition of that sensor. A comparison of the frequency of the front sensors with the rear sensor indicates something about the condition of the Cat.

This malfunction was detected when the ratio of the signal frequency from the right bank front Oxygen Sensor to the signal frequency of the rear Oxygen Sensor exceeded a critical threshold value. This indicates that the Cat does not have enough oxygen storage capacity. The right cylinder bank is also called the rear bank. It is cylinders 1,3,5. Possible causes of this DTC include ...
- Three-way catalyst
- Exhaust tube
- Intake air leaks
- Fuel injectors
- Spark plugs
- Ignition timing
