P0141 on a Honda: Causes, Fixes & Repair Cost

🟢 Low severity · drivable

Safe to drive; this code only affects how fast the oxygen sensor warms up, not how the car runs.

What P0141 means on a Honda

On a Honda, P0141 means the heater circuit inside the bank 1 downstream oxygen sensor (sensor 2) has failed. The heater just warms the sensor up faster after a cold start, so the car still drives normally, but the sensor reads slowly until it heats up on its own.

Is P0141 common on Hondas?

P0141 shows up on Hondas with higher mileage, often on Civic, Accord, CR-V, and Pilot models. Honda oxygen sensors wear out as the miles add up, and the heater element is the part that fails first. Connector corrosion near the exhaust is a less common cause.

Commonly reported on: Civic, Accord, CR-V, Pilot.

Symptoms

Check engine light is on
No change in how the car drives
Failed emissions test
Slightly higher fuel use until the sensor warms up

Common causes

most common: Heater element burned out inside the oxygen sensor
common: Corroded or damaged wiring near the sensor
less common: Blown O2 sensor heater fuse
rare: Bad ground in the heater circuit

How to fix it

Fix	DIY?	Typical cost
Replace the bank 1 downstream oxygen sensor	Yes	$80–190
Repair the sensor wiring or connector	Mechanic	$100–250
Replace the O2 sensor heater fuse	Yes	$5–15
