Signs You Need A New Sensor
Check engine light often signals a bad oxygen sensor. It may flash or stay on constantly. This light warns that the sensor is not working well.
Fuel efficiency drops because the sensor sends wrong data to the engine. This causes more fuel to burn, which wastes money and fuel.
Failed emissions test happens when the sensor cannot control exhaust gases properly. This causes more pollution and may stop your car from passing the test.
