P0141: O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
What this check-engine code means in plain English, what usually causes it, and what a fix typically costs.
What P0141 means
This code means the heated oxygen sensor (O2 sensor) located after the catalytic converter on Bank 1 has a problem with its internal heater circuit. The heater helps the sensor reach operating temperature quickly so it can monitor exhaust gases and catalytic converter efficiency. The engine computer detected that the heater circuit is not working properly.
What causes P0141?
Is P0141 safe to drive?
You can continue driving with this code as it does not affect immediate safety or drivability. However, the vehicle may use slightly more fuel and will likely fail an emissions test. Address it within a few weeks to prevent potential catalytic converter monitoring issues.
P0141 repair cost
Industry-average estimates. Cost depends on whether only the sensor needs replacement or if wiring repair is also required, plus labor access difficulty.
