P0141 means the heater circuit in your Bank 1 downstream (post-catalyst) oxygen sensor has failed. The heater brings the sensor to operating temperature quickly after a cold start. Without it, the sensor takes several minutes to warm up naturally from exhaust heat.

What does P0141 mean on a Volkswagen?
Volkswagen Golf
2005-2024VW uses Bosch sensors as OEM on most Golf models. The EA888 engine's downstream sensor can be tight to access due to the subframe. On TSI models, oil consumption issues can contaminate sensors prematurely, so check oil consumption if replacing sensors frequently.
What causes P0141 on a Volkswagen?
Beyond the generic causes listed on the main P0141 page, these are the Volkswagen-specific patterns we see most often:
Volkswagen GolfBosch sensor heater degradation at 90,000+ km
Volkswagen GolfOil contamination from EA888 oil consumption fouling the heater element
How to diagnose P0141 on a Volkswagen with OBD2
Follow these steps to pinpoint the root cause of P0141:
- Check for multiple heater codes (P0135, P0155, P0161). Multiple codes suggest a shared fuse or wiring issue, not individual sensor failures
- Check the O2 sensor heater fuse in the fuse box. Replace if blown and monitor for recurrence
- Unplug the Bank 1 Sensor 2 connector and measure heater resistance with a multimeter. Healthy: 2-15 ohms. Open circuit (infinite): burned-out heater. Under 1 ohm: short circuit
- Inspect the sensor connector for corrosion, bent pins, or water intrusion
- Trace wiring from connector toward ECU, checking for chafing or damage against heat shields or exhaust components
How much does P0141 cost to fix on a Volkswagen? (EUR)
Estimated repair costs on a Volkswagen (Volkswagen parts and labour typically run 15% above the average for this code).
Prices estimated as of May 2026. Costs vary by region, vehicle, and shop.

FAQ: P0141 on Volkswagen
Can I drive with P0141?
Yes, completely safe. The heater only affects how quickly the sensor reaches operating temperature. Once warm, it works normally. You'll use slightly more fuel during the first few minutes after a cold start.
What is the most common fix for P0141?
Replacing the downstream oxygen sensor on Bank 1. The heater element burns out over time and cannot be repaired separately. Costs 110-270 euros on most vehicles.
Can a blown fuse cause P0141?
Yes. O2 sensor heaters share a fuse. If it blows, you'll see multiple heater codes at once (P0141, P0135, P0155, P0161). Check the fuse before buying a new sensor.
How long do oxygen sensors last?
Most last 80,000-150,000 km. The heater element is typically the first component to fail. Oil contamination and rich running shorten sensor life.
