Code: P2196
Fault Location:
Oxygen (Lambda) Sensor (O2S) 1, Bank 1/Heated Oxygen Sensor (HO2S) 1 (G39), Bank 1 - Signal Stuck Rich
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Excessive Fuel Consumption.
Vacuum leaks.
Wiring/Connector(s).
Oxygen (Lambda) sensor (O2S).
Heated Oxygen Sensor (HO2S) 1 (G39).
Fuel pressure.
Injectors.
Air intake restricted.
Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Read Measuring Value Blocks (MVB).
Description:
The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The Engine Control Module (ECM) adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.
