O2 Sensor Signal Stuck Lean Bank 1 Sensor 1
P2195 is an OBD-II generic code for the engine control module (ECM) detecting the O2 sensor signal stuck lean for bank 1 sensor 1. The engine has tried to lean out a rich condition and failed.
The engine control module is getting a signal from the bank 1 sensor 1 it is overly rich in that side of the engine and has tried to lean the mixture out to its limit causing the code to be set.
The Check Engine Light will be illuminated and the code is set in ECM memory as a fault.
The engine may be running rough, rich, and misfiring.
Scans and documents the code in the ECM to check the freeze frame data for failure
Checks for any intake vacuum leaks or intake hose leaks between the mass air sensor and the throttle body
Checks for excessive fuel pressure
Checks the codes to see if only one or both sides of the engine are running rich
Checks the fuel injectors to see if one is leaking or stuck open
Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired
Failing to clear the ECM codes after the codes are fixed
Failing to check the air filter for damage, allowing air to enter the intake unmetered by the mass air sensor
Code P2195 is an indication that the ECM is getting a signal to go lean from the O2 sensor and has tried to lean out the mixture to its limit and the system is still too rich.
Code P2195 is for only one of the O2 sensors and may be accompanied with other O2 sensor codes if the problem is causing the entire engine to run rich like excessive fuel pressure or mass air sensor or tube problems.
