CEL 0114 Fuel INJ Sys Right bank:rich
Ok so this is the issue or code i am having,
this is all the info i could find... im not quite sure what the EVAP CVCV
is, or how to bench test it, i do know how to use ohm meters and volt meters, is there a certain amount of resistance this should have or what not?
i jsut got this CEL last nite, and would like to get on top of it before i cause anymore problems..any help would be great...

0114
Diagnostic Trouble Code 0114 indicates a problem with the fuel management system on the right cylinder bank. The right bank is also called the rear bank. It is cylinders 1,3,5.
The Front Heated Oxygen Sensor for the right bank sent signals to the Engine Control Module indicating an excessively rich fuel mixture. The ECM attempted to correct this problem by directing the fuel injectors to supply less gasoline. Further signals from the Oxygen Sensor indicate that the attempt to correct the rich mixture condition was unsuccessful, and the fuel mixture continues to be too rich.
Possible causes include ...
- Intake air leaks
- Defective Front Heated Oxygen Sensor
- Fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow Sensor
Before tackling anything involving DTC 0114, I would bench test the EVAP CVCV first. It probably needs replacement. Then I would reset the ECU and see if the light comes back indicating you are still running rich on the rear cylinder bank. Most likely, the 0114 will be an Oxygen Sensor if replacing the EVAP CVCV didn't resolve everything..

The CVCV is the EVAP Canister Vent Control Valve. What year max do you have? If your ECU isn't faulty, then the screw method will both check and clear codes.
EDIT: I see you have a '99.
