P0141 Chevrolet - will I need to replace the o2 sensor?

Question

If a code p0141 came up will I need to replace the o2 sensor?

Answer 1

Hi there

In most cases the heated O2 sensor is the problem and will need to be replaced. Occasionally it can be the wiring to the sensor which is usually what is tested prior to replacing the sensor, but most common issue is the sensor itself.
