There is a problem with the heating element on the front, or pre-catalytic converter oxygen sensor.
What P0141 really means:
What are the symptoms a P0141 code?
We might not notice any change in the performance of the car. Normal operating temperature for an oxygen sensor will be around 600 degrees fahrenheit, whereas exhaust gas temperatures will be higher than this when the car has warmed up. Of course, the oxygen sensor will not work at peak performance, and you might see a dip in fuel economy. Carbon and other deposits will build up at a faster rate in the engine and in the catalytic converter. Oxygen sensors, when working well, help the engine run at peak efficiency.
What is the severity of a P0141 code?
What repairs are needed to resolve a P0141 code?
Replacing the front oxygen sensors. Though you will not be stranded on the side of the road, remember that the car is not running as efficiently, which will lead to more significant problems (and more money) down the road. Carbon build up in the engine and deposits on the catalytic converter could cost you far more money than even the most expensive sensors.
What’s the cost to resolve a P0141 code?
- Estimated Cost for Part(s)= $150-350
- Estimated Labor Cost = $50-300 (depending on vehicle type)
- Estimated Total Cost = $200-$650
