P0141 on Honda: Causes, Symptoms and Fix Cost
Quick Answer
Safe to drive (short-term)
P0141 on a Honda 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.

- Low · Emissions
- Typical repair cost, all makes
- €1-€370
Connect a standard OBD2 adapter (Bluetooth LE on iPhone) to your Honda and Skanyx tells you what P0141 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Honda models that log P0141.
Honda Civic
2006-2021
The Civic hatchback sold in Europe from 2006 to 2011 used the 1.8 litre R18A petrol engine, and the tenth generation (2016 to 2021) offers the 1.5 litre turbo L15B7. Measure the heater's resistance and compare it with the specification for your sensor before replacing the sensor.

What causes P0141 on a Honda?
Beyond the generic causes listed on the main P0141 page, these are the patterns noted for Honda models:
Open or shorted heater element in the downstream sensor
: Honda Civic
Damaged wiring or connector at the downstream sensor
: Honda Civic
How to diagnose P0141 on a Honda with OBD2
- 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
