Frequently Asked Questions
What does P0061 mean?
P0061 indicates the heater resistance in the Bank 2 Sensor 3 oxygen sensor is outside the normal range, typically due to a degrading heater element.
Is P0061 common?
P0061 is relatively uncommon since only vehicles with multiple catalytic converters per bank have a Sensor 3 position. It is mostly seen on V6 and V8 engines.
How urgent is P0061?
P0061 is low severity and does not require immediate repair. However, it will cause an emissions test failure if active.
