You can keep driving. Get it checked when convenient.

Can I drive with P0141?

Yes, you can keep driving. Post-catalytic sensor heater is burned out; usually safe to drive for a short time, but get it checked to drive for a short time, but get it checked.

What does P0141 mean?

P0141 stands for O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).

  • Check engine light illuminated
  • Slightly increased tailpipe emissions during the first 3 minutes of warm-up
  • Normal engine performance once warmed up

How much does it cost to fix?

Repair costs for code P0141 depend on the specific underlying root cause, ranging from simple DIY checks to component replacement. The table below lists the most common causes and rough price ranges in USD:

  • Burned out heater coil inside the sensor
    $70-$190 common
  • Blown downstream O2 heater fuse
    $5-$15 common

    $20-$50 possible
  • Melted harness touching the exhaust pipe
    $35-$90 rare

What to do next

About this code

Code P0141 is one of the most benign check engine codes. It simply indicates that the electric heating element inside the rear oxygen sensor has burned out. Once the car is driven for a few miles, the catalytic converter gets scorching hot anyway, warming the sensor naturally. You can continue driving without damaging your vehicle.
