A/F (O2) Sensor Signal Biased/Stuck Lean Bank 1 Sensor 2 Circuit Current Above Threshold |

P227118 |
A/F (O2) Sensor Signal Biased/Stuck Rich Bank 1 Sensor 2 Circuit Current Below Threshold |
While the fuel-cut operation is performed (during vehicle deceleration), the air fuel ratio sensor (sensor 2) current is less than 7.5 mA for 0.5 seconds or more (2 trip detection logic). |
|

DTC stored |
|
HINT:
- When any of these DTCs are stored, check the air fuel ratio sensor (sensor 2) current output by entering the following menus on the Techstream: Powertrain / Engine / Data List / A/F (O2) Sensor Current B1S2.
- Short-term fuel trim values can also be read using the Techstream.
- If an air fuel ratio sensor (sensor 2) malfunction is detected, the ECM will store a DTC.
MONITOR DESCRIPTION
A rich air fuel mixture causes a low air fuel ratio sensor (sensor 2) current, and a lean air fuel mixture causes a high air fuel ratio sensor (sensor 2) current. Therefore, the sensor output becomes low during acceleration, and it becomes high during deceleration with the throttle valve fully closed. The ECM monitors the air fuel ratio sensor (sensor 2) current during fuel-cut and detects any abnormal current values.
If the air fuel ratio sensor (sensor 2) output is 33.13 mA or more for 0.5 seconds or more of cumulative time, the ECM interprets this as a malfunction of the air fuel ratio sensor (sensor 2) and stores DTC P227019 (stuck on high side). If the air fuel ratio sensor (sensor 2) output is less than 7.5 mA for 0.5 seconds or more of cumulative time, the ECM stores DTC P227118 (stuck on low side).

CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
HINT:
- Sensor 1 refers to the sensor closest to the engine assembly.
- Sensor 2 refers to the sensor farthest away from the engine assembly.
