Details of the Ford p2197 OBD Code
The Ford P2197 code indicates a lean condition in bank 2 of the engine.
Ford OBD code P2197 means that the O2 sensor signal stuck lean in bank 2. This code is triggered by the Engine Control Module (ECM) when the downstream O2 sensor in bank 2 consistently reads a lean air/fuel mixture for an extended period.
This indicates that there is an imbalance in the airfuel ratio in that bank of cylinders.
The ECM uses this information to adjust the fuel mixture to maintain proper combustion.
Mechanic’s Tech Notes
Troubleshooting information for Ford code P2197 related to a lean mixture in bank 2.
To diagnose and fix OBDII code P2197 on a Ford, start by checking the oxygen sensor (Bank 2 Sensor 1) for proper operation.
Use a voltmeter to test the sensor’s voltage output and ensure it fluctuates correctly.
Inspect the sensor wiring for any damage or corrosion.
Next, check for vacuum leaks in the intake system, which can cause a lean condition.
Use a smoke machine or propane enrichment method to identify leaks.
Additionally, verify the fuel pressure to ensure it meets specifications.
If all checks out, consider cleaning the MAF sensor and throttle body to improve airfuel mixture accuracy.
