My check engine light just came on so i ran it and it is coming up with code P2180. Does anyone have any idea what this might be?

 

Neither one of my code lists has it.

 

The car is a 2003 and after the code it said "system to rich off idle speed (bank 2)"

 

Direct from VADIS for your code P2180= Volvo Code ECM-271A

Diagnostic trouble code(DTC) information

The control module receives information from the heated oxygen sensor (HO2S) about the fuel / air mixture when idling at both the lower and upper part-load range. If the fuel / air mixture deviates from A=1, the short-term fuel trim will compensate for this by adjusting the injection time so that A= 1 is achieved. When the short-term fuel trim makes an adjustment, the integrator median must be adjusted by the long-term trim. Diagnostic trouble code (DTC) ECM-271A will be stored when the long-term trim must be adjusted to almost maximum in the lower part load area.

Substitute value: None

Possible source

Upper limit:
-intake air leakage
-exhaust system air leakage
-low fuel pressure
-defective heated oxygen sensor (HO2S)

Lower limit:
-intake air leakage
-high fuel pressure
-leaking injectors
-defective mass airflow (MAP) sensor
-contaminated engine oil -oil level too high
-defective heated oxygen sensor (HO2S) Fault symptom
