The oxygen sensor in a car does not start operating properly until the car has warmed up. The car's engine control module, or ECM, monitors this and measures how long the sensor takes to start working. It knows this based on factory information and the temperature of the coolant in the vehicle. If the oxygen sensor is taking longer than it should to start operating, it reports the trouble code P0141. Replacing the oxygen sensor is a common fix for this problem. Often the engine light comes on and the car's fuel economy is not what it should be, meaning it consumes more fuel.
This code appears in a range of different cars, including Acura, Audi, BMW, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Honda, Hummer, Hyundai, Infiniti, Isuzu, Jeep, Kia, Lexus, Mazda, Mercedes-Benz, Mitsubishi, Pontiac, Nissan Saturn, Scion, Toyota and Volkswagen.Learn more about Computer Help
