P0141 on a Volvo: Causes, Fixes & Repair Cost

🟢 Low severity · drivable

The car remains drivable because the heater only affects sensor warm-up speed, not engine performance.

What P0141 means on a Volvo

On a Volvo, P0141 points to a failed heater circuit in the bank 1 downstream oxygen sensor. The rear sensor tracks converter performance and doesn't control fuel, so the Volvo keeps running normally with the light on.

Is P0141 common on Volvos?

Higher-mileage Volvos like the S60, XC60, and XC90 develop this code as the rear sensor heater ages. Volvo uses Bosch-style oxygen sensors, and the part can be pricier than on mainstream brands.

Commonly reported on: S60, XC60, XC90, V70.

Symptoms

Check engine light is on
Emissions test may fail
Slightly reduced fuel economy
No drivability problems

Common causes

most common: Heater element burned out inside the rear sensor
common: Blown oxygen sensor heater fuse
common: Damaged wiring or connector near the sensor
less common: Corrosion in the sensor connector
