센스를 바꾸고 나서는 O2 code는 나오지 않고 OBDII 코드가 P1123만 나왔습니다. 현대 서비스 사이트에서 찾아보니 체크 할 것이 한두개가 아니네요.
딜러에서 처음에 제시한 것이 에어쪽과 퓨얼쪽을 크린하고 옥시전 센스바꾸고 pcsv 바꾸는데 $1000 을 제시했는데 이것 저것 전부 다하면 어딜 가도 그 정도 나오것 같네요.
AUTO ZONE 에서는 MASS AIR 라고 이야기 했는데 그건또 뭔지. 인스펙션만 아니면 그냥 고치지 않고 타고 다닐텐데.

Fuel Trim Additive Air System Too Rich
Fuel Trim Additive Air System Too Lean
Long Term Fuel Trim Multipicative System Too Rich
Long Term Fuel Trim Multipicative System Too LeanDESCRIPTION
The air/fuel control system, in addition to a number of sensors, includes the following components and systems:
Intake air system.
Exhaust system.
Evaporative emissions control system (includes purge control solenoid valve).
Fuel injectors.
Fuel pressure regulator.
Fuel pump.For the air/fuel ratio to be within limits, all of the sensors, components and systems associated with the air/fuel control system must function within normal parameters.
FAILURE CONDITIONS
(FOR SHORT-TERM FUEL TRIM)
The ECM will set a code and the Malfunction Indicator Lamp (MIL) will turn on if the short-term fuel trim value goes 10% to 15% rich [for P1123] or if the short-term fuel trim additive value is less than 0.4 milliseconds, or 10% to 15% lean [for P1124] for 30 seconds during two driving cycles when the following conditions are met:ECM is in closed loop operation.
Engine speed is below 1000 RPM.
Engine coolant temperature is above 158°F (70°C).
Canister purge system is not operating.
Mass air flow is less than 7.5 g/s [for P1123] or 5.5 g/s [for P1124].(FOR LONG-TERM FUEL TRIM)
The ECM will set a code and the Malfunction Indicator Lamp (MIL) will turn on if the long-term multiplicative value is less than 77% for 30 seconds [for P1127] or if the long-term fuel trim value goes to 10% to 15% lean [for P1128] for 30 seconds during two driving cycles when the following conditions are met:Engine load exceeds 1.8 milliseconds.
ECM is in closed loop operation [for P1127].
Engine coolant temperature is above 158°F (70°C).
Canister purge system is not operating.
Mass air flow is less than or 5.5 g/s.
Engine speed is below 1000 RPM [for P1128].TEST PROCEDURE
