DTC P2195-19: A/F (O2) Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1 Circuit Current Above Threshold; DTC P2195-24: A/F (O2) Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1 Signal Stuck High; DTC P2196-18: A/F (O2) Sensor Signal Biased/Stuck Rich Bank 1 Sensor 1 Circuit Current Below Threshold; DTC P2196-23: A/F (O2) Sensor Signal Biased/Stuck Rich Bank 1 Sensor 1 Signal Stuck Low [10/2022 - 11/2023]: Description
WARNING: This page is about a different variant/trim than selected.
Refer to DTC P0030-12.
Refer to DESCRIPTION
HINT:
Although the DTC titles say O2 sensor, these DTCs relate to the air fuel ratio sensor (sensor 1).
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P2195-19 | A/F (O2) Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1 Circuit Current Above Threshold | While the fuel-cut operation is performed (during vehicle deceleration), the air fuel ratio sensor (sensor 1) current is 2.2 mA or more for 3 seconds (2 trip detection logic). |

HINT:
- When any of these DTCs are stored, check the air fuel ratio sensor (sensor 1) current output by entering the following menus on the GTS: Powertrain / Engine / Data List / A/F (O2) Sensor Current B1S1.
- Short-term fuel trim values can also be read using the GTS.
- If an air fuel ratio sensor (sensor 1) malfunction is detected, the ECM will store a DTC.
