Diagnostic Trouble Code
P2195 - Lack of HO2S-11. Switch, Sensor Indicates Lean

Descriptions: A Heated Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

Check the wiring leading to the first O2 sensor located in the exhaust stream. The O2 sensor may have been damaged or worn to the point where it may need replacement.

Is the code reader showing fault code P2195?

If not, could you please post back with the correct code?
