Advanced Diagnostics - DTC P2197: Front Air/Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) Signal Stuck Lean
General Description
When the front air/fuel ratio (A/F) sensor (bank 2, sensor 1) is properly connected to the engine wire harness, but it is not installed in the exhaust pipe, the feedback is not done properly even if the front A/F sensor is active after starting the engine. Thus, the exhaust emissions increase. When the front A/F sensor output stays out of the normal range after the front A/F sensor becomes active, the powertrain control module (PCM) detects that the front A/F sensor is not properly installed and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type, OBD Status
Enable Conditions
Malfunction Threshold
The front A/F sensor (bank 2, sensor 1) output voltage is 3.37 V or more for at least 7.0 seconds.
Driving Pattern
Start the engine, and let it idle for at least 2 minutes.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
